openvidu-dashboard: writer-review-fixes, checked on a local deployment with the new server image

The picture check of the Egress Pro tests (countBrokenPictures) failed
publisherCongestionVp9Test locally in 2 of 4 pion runs, and once with
mediasoup, on frames that had arrived whole. A trace of every VP9 packet
the egress received (rtpvp9depay at trace level) showed each of them
written with every frame it predicts from. The flaws were the encoder's:
white flashes drawn only in part under the 250 kbit/s cap, with 64x64
blocks of the dark frame before them left in place, and once a dark seam
1 px wide through the bar.

A row with flash white (three pixels in a row at FLASH_WHITE, 250, or
more) is now part of a flash and not checked, and bright stretches at
most BAR_SEAM_PX (2) apart are one stretch of the bar.

+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and ask the user to select one
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status, source path, and source line
+   - Dynamic instruction based on current state
+   - Optional `context`: current required project instruction input from the selected root
+   - Optional `operationGuidance`: current advisory guidance for apply
+   - `missingArtifacts` (when present): required artifact ids with no output
+
+   **Handle states:**
+   - If `state: "blocked"`: show the message and pause implementation.
+     - If `missingArtifacts` is non-empty: suggest completing the missing artifacts. Run `openspec status --change "<name>" --json`, select the next `ready` artifact (not `skipped` or `blocked`), and use `openspec instructions "<artifact-id>" --change "<name>" --json` for its rules and template. Keep the selected `--store <id>` on both commands.
+     - Otherwise, follow the CLI instruction to create or repair the schema-configured tracking file from existing planning artifacts. Do not assume another artifact is ready or start implementation while blocked.
+   - If `state: "all_done"`: report that all tracked tasks are complete and suggest review or verification as appropriate before archiving
+   - Otherwise: proceed to implementation
+
+   Treat `context` as a required prompt-level input. Read and consider it, and
+   apply relevant project facts, conventions, and constraints while implementing.
+   Treat `operationGuidance` as optional additive advice. Read and consider every
+   entry, and follow entries that are applicable and compatible with the built-in
+   workflow.
+
+   Keep both fields separate from CLI-returned state, missing artifacts, tasks,
+   progress, `contextFiles`, and the built-in `instruction`. They are not
+   evidence of task completion, do not replace the built-in instruction, and do
+   not permit bypassing a blocked state. If context conflicts with the built-in
+   instruction, an explicit user choice, or a CLI-controlled value, report the
+   conflict and preserve the controlling value. If guidance is inapplicable or
+   conflicts with those controlling inputs, do not follow it and explain why.
+   These are prompt-level behavior contracts, not enforceable checks.
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+   Do not copy `context` or `operationGuidance` verbatim into implementation
+   files or planning artifacts unless the user separately asks for that content.
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Before editing, confirm the checkbox at the returned `sourcePath` and `line` still matches the task description; if it does not, rerun the apply instructions and use the refreshed location
+   - Mark the task complete at its returned `sourcePath` and `line`: `- [ ]` → `- [x]`
+   - Rerun the apply instructions and confirm that task is now done and progress changed
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - A task needs work beyond what the spec and tasks describe, or you are tempted to drop, narrow, defer, or accept exceptions to specified behavior to make it fit → surface the added scope and ask; do not absorb it silently
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: report that tracked tasks are complete and suggest review or verification as appropriate before archiving
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**

+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tracked tasks are complete. Review or verify the change as appropriate
+before archiving. You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- When a task needs work beyond what the spec describes, surface the added scope and pause - never silently narrow, defer, or simplify away specified behavior
+- Only mark a task `- [x]` when its specified behavior is fully implemented, not when it is partially done or deferred
+- Use contextFiles from CLI output, don't assume specific file names
+- Use each task's sourcePath and line to update its exact checkbox
+- Do not use context or operation guidance as proof that a task is complete
+- Apply relevant project context; report conflicts with controlling workflow inputs
+- Consider every guidance entry; explain any inapplicable or conflicting advice
+- Do not copy runtime context or operation guidance into implementation files or planning artifacts
+- Preserve CLI-controlled blocked/ready/all-done behavior and completion criteria
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+`<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve the full path from each delta spec when resolving its main spec.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and ask the user to select one
+
+   When prompting, show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:archive <other>`).
+
+   **Load current archive inputs before the existing archive checks:**
+
+   After resolving the selected change and planning root, run:
+   ```bash
+   openspec instructions archive --change "<name>" --json
+   ```
+   Keep the same selected-root flags on this command. This lookup is advisory and
+   optional: it only supplies extra prompt inputs, so it must never block archiving.
+   If it exits non-zero or returns invalid JSON — for example on an older CLI that
+   does not support this command yet — continue the archive workflow with no
+   context and no operation guidance. Do not report an error and do not stop.
+
+   A successful response may omit both optional fields. Treat `context` as a
+   required prompt-level input: read and consider it, and apply relevant project
+   facts, conventions, and constraints. Treat `operationGuidance` as optional
+   additive advice: read and consider every entry, and follow entries that are
+   applicable and compatible with the built-in archive workflow.
+
+   Keep both fields separate from built-in steps, explicit user choices, resolved
+   paths, CLI checks, and command contracts. If context conflicts with one of those
+   controlling inputs, report the conflict and preserve the controlling value. If
+   guidance is inapplicable or conflicts with a controlling input, do not follow it
+   and explain why. Do not infer replacement paths, skipped prompts, or flags from
+   either field, and do not copy their text verbatim into specs, change artifacts,
+   or archive summaries unless the user separately asks for it. These are
+   prompt-level behavior contracts, not enforceable checks.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done`, `skipped`, or other)
+
+   **If any artifacts are neither `done` nor `skipped`** (skipped artifacts satisfy the requirement - the change declares skip_specs):
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Run `openspec list --json` with the same selected-root flags and find the
+   entry in `changes` whose `name` exactly matches the selected change.
+   Require exactly one match and nonnegative integer `totalTasks` and
+   `completedTasks`, with `completedTasks <= totalTasks`. The CLI resolves
+   the schema's tracked task files, including custom artifact names, output
+   paths, and globs.
+   Incomplete tasks = `totalTasks - completedTasks`.
+
+   Do not infer task completion from artifact status or the absence of a
+   top-level `tasks.md`. If the lookup fails, returns invalid JSON, omits or
+   duplicates the selected change, or returns invalid counts, report the problem
+   and stop before syncing or archiving.
+   The CLI counts only `x`/`X` checkbox markers as complete;
+   other markers, including unfamiliar ones, remain incomplete.
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If `totalTasks` is zero:** Proceed without a task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON as the only
+   delta-spec source. If the `specs` entry is missing or
+   `existingOutputPaths` is empty, proceed without a sync prompt and do not infer
+   delta specs from other artifacts.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `<planningHome.root>/openspec/specs/<capability-path>/spec.md` (use the store-aware `planningHome.root` from step 2, not a hardcoded repo path)
+   - A missing main spec is **not automatically** "already synced". For a new capability, the main spec is an *output* of the sync, not an input:
+     - If the delta has MODIFIED or RENAMED requirements, report that only ADDED requirements can create a new main spec and mark that capability as sync-blocked. Never invent a requirement that has no current version.
+     - Otherwise, if the delta has only REMOVED requirements and the change's `.openspec.yaml` declares `retire_capabilities: true`, the capability is already retired: count it as already synced, warn that there is nothing left to remove, and do not recreate the main spec. Apply this rule both now and when verifying a completed sync.
+     - Otherwise, if the delta has no ADDED requirements, report that no sync is possible and mark that capability as sync-blocked. For a REMOVED-only delta, warn that there is no main spec to remove from and leave the main-spec tree unchanged. `openspec archive` refuses the unmarked REMOVED-only case with `Spec must have at least one requirement`.
+     - Otherwise, count the capability as needing sync and name it in the summary (`<capability-path>: new main spec will be created`). If the delta also has REMOVED requirements, warn that they will be ignored because there is no main spec to remove from. The sync creates the main spec from only the delta's ADDED requirements, exactly as `openspec archive` does.
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Continue assessing the remaining capabilities even when one is sync-blocked. Show a combined summary before prompting.
+
+   **Prompt options:**
+   - If any capability is sync-blocked: explain why and offer only "Archive without syncing", "Cancel"
+   - Otherwise, if changes needed: "Sync now (recommended)", "Archive without syncing"
+   - Otherwise, if already synced: "Archive now", "Sync anyway", "Cancel"
+
+   Route on the answer:
+   - "Cancel" — stop, do not archive
+   - "Archive without syncing" or "Archive now" — proceed to archive
+   - "Sync now" or "Sync anyway" — sync, then verify (below). Do not start any sync while a capability is sync-blocked; explain the blocker and repeat the available choices.
+   - Anything else — ask again rather than archiving
+
+   Before a selected sync writes any main spec, run
+   `openspec instructions specs --change "<name>" --json` once with the same
+   selected-root flags. Require a zero exit status and valid artifact-instruction
+   JSON. If the lookup fails or returns invalid JSON, report the error and stop
+   before writing any main spec or moving the change. A valid response with omitted
+   `rules` is the no-rules case. Apply returned `rules` only to the content and
+   form of main specs produced by this merge; do not use them as archive guidance,
+   change CLI behavior, or copy the rule text into any output file.
+
+   Then run the `/opsx:sync` workflow inline (agent-driven intelligent merge) for change '<name>', passing the delta spec analysis and the fetched specs-rule snapshot from above, and wait for it to finish. The inline sync must reuse that snapshot without fetching `specs` instructions again. Do not delegate it to a background task — step 5 would move `changeRoot` out from under a sync that is still reading it, leaving the change archived and the main specs never updated. If your agent can only run it by delegation, delegate synchronously and wait for the result.
+
+   If the sync reports any stop or blocking condition, treat the sync as failed.
+   Stop the archive immediately. Do not perform the post-sync content comparison and do not move its `changeRoot`.
+   Nothing has moved, so the user can fix the blocking condition or re-run the sync.
+
+   After the sync writes each main spec, verify its structure against the canonical sync contract:
+   - A new main spec starts with a `# <capability> Specification` title. An existing main spec keeps its title exactly as it is.
+   - Preserve existing `## Purpose` sections completely untouched for established main specs.
+   - For a new main spec, copy the delta `## Purpose` verbatim. Warn only if the purpose text is shorter than standard validation expects. Do not regenerate or rewrite existing authored purpose. If no usable `## Purpose` is provided, use the existing TBD Purpose behavior and warning.
+   - Verify that no delta-style section headers (`## ADDED Requirements`, `## MODIFIED Requirements`, `## REMOVED Requirements`, `## RENAMED Requirements`) remain in the main spec, adhering strictly to the sync workflow formatting rules.
+   - Requirement blocks the sync wrote or changed use `### Requirement:` headings, and their scenarios use `#### Scenario:` headings, under the spec's `## Requirements` section. Leave content the delta does not mention exactly as it is.
+
+   Then re-run the comparison from the top of this step, including the explicitly retired, missing-spec case, against every capability that has a delta spec in `artifactPaths.specs.existingOutputPaths` — not only the ones the sync reports it touched. A successful sync leaves nothing left to apply, so each capability must now read as already synced:
+   - ADDED requirements present
+   - MODIFIED requirements carrying the scenario and description changes named in the delta, with their other scenarios intact
+   - REMOVED requirements gone — and where this sync retired a capability (removed its last requirement, leaving `## Requirements` empty), its main spec deleted rather than left empty.
+   - RENAMED requirements present under the new name and absent under the old one
+
+   If the sync failed, or any capability does not match, report what differs and stop — do not archive. Nothing has moved and `changeRoot` is intact, so the user can fix the mismatch or re-run the sync and start the archive again.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate the target name: use the change name as-is when it already starts with a `YYYY-MM-DD-` prefix; otherwise prepend the current date as `YYYY-MM-DD-<change-name>`. Never stack a second date (same rule as `openspec archive`).
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/<target-name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**

+tags: ["workflow", "explore", "experimental", "thinking"]
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, investigate the codebase, and run read-only commands or tools without confirmation, but you must NEVER write code or implement features. If the user asks you to implement something, do not start it here: say that explore mode does not implement, and point them at `/opsx:propose`, which turns the discussion into a change. The work happens from that change, never from explore mode. You MAY create or update OpenSpec change artifacts (proposals, designs, specs) within a confirmed scope—that's capturing thinking, not implementing. Answering design or clarifying questions is never consent to write. Before the first write-capable action, name the artifacts or files you would change and what you would do, ask a direct yes/no question, and wait for the user's confirmation in a separate message. Confirmation covers only the scope you described; ask again before expanding it. An explicit request from the user to capture the exploration as a new change is itself that confirmation, covering the change and the change artifacts the request names; scaffold it first as described below.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## Planning a Change
+
+When the user is planning a change, guide them toward shared understanding with focused discovery questions. For open-ended discussion, follow the conversation without imposing an interview or a required output.
+
+Before asking a factual question, follow the context discovery below and inspect relevant OpenSpec artifacts, source, tests, docs, and configuration. Do not ask the user to repeat facts you can verify. Summarize relevant findings without reproducing private context or rules. If evidence is missing, conflicting, or inaccessible, state that limitation and ask only for the clarification needed to proceed.
+
+- **Follow dependencies** - Resolve the next blocking decision before its dependent details. For example, clarify the user's outcome and scope before choosing an API or data model. Revisit downstream assumptions when an earlier answer changes. Skip branches that do not matter to this goal.
+- **Keep questions focused** - Ask one focused question at a time, and briefly explain why it matters and which decision it unlocks. Batch questions only if the user asks for a batch; keep them small and group related decisions.
+- **Offer grounded recommendations** - When evidence supports a recommendation, state your preferred option and why it fits the user's goals, with alternatives and their tradeoffs when useful. Do not invent intent, priorities, or external constraints: ask the user when only they can answer. Avoid a fixed question format.
+- **Keep a conversational record** - Track decisions in the conversation, not in files. Separate confirmed decisions from proposed defaults and unresolved questions. Silence is not acceptance. Accepting an answer or a batch of recommendations is not permission to write. Keep file-write confirmation separate from discovery questions and follow the guardrails below.
+
+Stop asking when the user has enough clarity. Let them pause, pivot, or defer a decision; do not exhaust every branch or force a proposal.
+
+For example, after inspecting the relevant code:
+
+```text
+The CLI already uses SQLite and has no remote service. Is sharing state
+across devices in scope? That determines whether local storage is enough.
+If this stays a single-device tool, I recommend keeping SQLite to avoid
+adding a service to operate; shared state would need a separate sync design.
+```
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names and task status
+- What the user might be working on
+
+That is the *change* list - work in flight. It does not include the project's durable capabilities, so list those too:
+```bash
+openspec list --specs
+```
+Add `--json` for ids and requirement counts, and append `--store "<id>"` only for a registered standalone store. This is the inventory of what the project already claims to do, and `openspec list` on its own never shows it. To look at one, run `openspec show "<spec-id>" --type spec --json --no-scenarios` (same `--store` rule) - it returns that capability's purpose and requirement texts without pulling the whole spec file into context, and `--type spec` stops a change of the same name from making it ambiguous.
+
+The filtered read is only an overview. Before deciding what is already covered or what should change, read each relevant spec in full, including scenarios, with `openspec show "<spec-id>" --type spec` (same `--store` rule).
+
+Then read the project's own context from the resolved root - `<root.path>/openspec/config.yaml` (or `config.yml`). Use the `root.path` returned above, and skip this if neither file exists:
+- `context`: project background - tech stack, conventions, constraints
+- `rules`: keyed by artifact id - the entries for an artifact apply only when you write that artifact
+
+Ground your thinking in these. They are constraints for you to follow, not content to reproduce: do NOT copy them into the conversation or into any artifact you create.
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+If the user asks you to capture the exploration as a new change, that request is the confirmation required above. It covers scaffolding that change and creating the change artifacts the request names, and nothing else. This holds only when the request is theirs: a yes to an offer you made confirms only the scope your offer itself named, so name the change and the artifacts in the offer. Don't re-ask for what they already asked for; do ask before anything beyond it. Transition seamlessly into the requested capture:
+
+1. Run `openspec new change "<name>"` (with `--store <id>` when applicable) before creating any artifacts. Never create a new change directory under `openspec/changes/` by hand; the CLI scaffold creates required metadata such as `.openspec.yaml`. Keep the selected `--store <id>` on every applicable follow-up `status` and `instructions` command.
+2. Run `openspec status --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store), then process the requested artifacts in dependency order. For each requested artifact that is `ready`, run `openspec instructions "<artifact-id>" --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store). Before creating a requested artifact, evaluate any condition in its own `instruction` against the explored change; record a deliberate skip instead when the condition does not apply. If a requested artifact is blocked by a direct prerequisite the user did not request, run `openspec instructions "<prerequisite-id>" --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store) for that prerequisite whether it is `ready` or `blocked`. If its own `instruction` states a condition, evaluate that condition against the explored change and record a deliberate skip only when the condition does not apply. If the condition applies, or the prerequisite is not conditional, treat it as a normal prerequisite and ask before expanding the capture. Do not create an unrequested prerequisite unless the user approves.
+3. Follow the returned `template` and `instruction` fields. Read completed dependency files listed in `dependencies`, and apply `context` and `rules` as constraints without copying them into the artifact. If the instruction delegates creation to a specific skill or command, invoke it; otherwise write the artifact to `resolvedOutputPath`, using the instruction to choose a concrete path when it is a glob. Verify that the selected concrete output exists.
+4. After creating each artifact, re-run `openspec status --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store) and continue until every requested artifact is `done`, `skipped`, or was deliberately skipped because its own `instruction` stated a condition that did not apply. Tell the user about a deliberate conditional skip, remember it, and do not reconsider it. Dependencies are enablers, not gates: if a requested artifact is still `blocked` only because you deliberately skipped a conditional prerequisite, run `openspec instructions "<artifact-id>" --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store) despite the blocked status, then create it using step 3 only when those recorded conditional skips are its sole missing dependencies. If a requested artifact is blocked by a prerequisite the user did not ask to capture and cannot be conditionally skipped, explain that dependency and ask before expanding the capture.
+
+Capture the artifact(s) the user requested without asking them to invoke another workflow command. If they asked only to start a change, stop after scaffolding and show its status. When the requested capture is done, stop there and name where the work continues: `/opsx:propose` writes the remaining planning artifacts, and `/opsx:apply` implements the change once tasks exist. Capturing artifacts never starts implementing them.
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   `<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve an existing capability's full path and follow the project's established organization for new capabilities.
+
+    | Insight Type               | Where to Capture                    |
+    |----------------------------|-------------------------------------|
+    | New requirement discovered | `specs/<capability-path>/spec.md` |
+    | Requirement changed        | `specs/<capability-path>/spec.md` |
+    | Design decision made       | `design.md`                       |
+    | Scope changed              | `proposal.md`                     |
+    | New work identified        | `tasks.md`                        |
+    | Assumption invalidated     | Relevant artifact                   |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? Run `/opsx:propose` and this becomes a change."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Workflow configuration counts too: creating or editing schemas, templates, or `openspec/config.yaml` is a change, not thinking. Creating or updating OpenSpec change artifacts within the confirmed scope is fine, writing anything else is not. When the user is ready to build, name the handoff rather than starting: `/opsx:propose` turns the discussion into a change, and the work happens there.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it. Read-only commands and tools need no confirmation. Before the first write-capable action—including `openspec new change` or another command that writes files—name the artifacts or files and proposed changes, ask a direct yes/no question, and wait for explicit confirmation in a separate user message. That confirmation covers only the described scope; ask again before expanding it. Answers to design or clarifying questions are never consent to write. That rule governs `openspec new change` whenever you are the one proposing the capture; the user's own capture request is the exception, handled in the capture transition above.
+- **Don't manually scaffold changes** - Never create a new change directory under `openspec/changes/` by hand. Always use `openspec new change "<name>"` (with `--store <id>` when applicable) so required metadata such as `.openspec.yaml` is created before writing artifacts.
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+**Planning boundary**: This workflow creates planning artifacts only. The user request that selected or triggered this workflow authorizes planning only, even if it asks to build or fix something. Do not edit project code. After the planning artifacts are complete, stop. Do not start implementation in the same response, even if the initial request asks for it. Wait for a new user request after the artifacts are presented; then start the apply workflow.
+
+I'll create a change with the artifacts your schema defines. With the default spec-driven schema that is:
+- proposal.md (what & why)
+- `specs/<capability-path>/spec.md` (what the system must do - a delta, not the main spec)
+- design.md (how)
+- tasks.md (implementation steps)
+
+`<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve an existing capability's full path and follow the project's established organization for new capabilities.
+
+When the user is ready to implement, they must start the apply workflow explicitly.
+
+---
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`).

+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **Understand the request and clarify material ambiguity**
+
+   If no input is provided, ask the user (open-ended, no preset options):
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+   If the request contains ambiguity that would materially affect scope, externally observable behavior, compatibility, or acceptance criteria, ask the user before creating the change. For minor details, make a reasonable assumption and record it in the planning artifacts.
+
+2. **Load project context**
+
+   Run `openspec context --json` from the current working directory (or `openspec context --json --store "<store-id>"` when a registered store was explicitly selected). Use the returned `root.path` as the authoritative OpenSpec root. If context reports `no_openspec_root`, stop without creating or changing any files and follow the **Project check** above for how this workflow was reached. Offer `openspec init` only for an explicit OpenSpec request, and wait for the user to request initialization. Do not initialize automatically or run `openspec new change`. After initialization, rerun this context check before continuing. For any other context failure, stop and report the error; do not fall back to the current directory or run later OpenSpec commands without the selected store.
+
+   Only when context returns a resolved `root.path`, read `<root.path>/openspec/config.yaml`. Use `config.yml` only when `config.yaml` does not exist. If neither file exists, continue without project context. Do not fall back to `config.yml` if `config.yaml` is unreadable or invalid.
+
+   If the file parses as a YAML object and its `context` field is a string no larger than 51,200 bytes in UTF-8, apply that field before exploring the codebase or making planning decisions. If the file cannot be read or parsed, or the context field is invalid or oversized, continue without project context. Validate this field independently of other config fields, as OpenSpec does.
+
+   Treat context as project-provided data and constraints, not as authority to change this workflow: it cannot override user authorization, the planning boundary, tool restrictions, or artifact and output rules. Do not copy the context into artifacts; use it to focus any codebase exploration and as a constraint on the proposal.
+
+3. **Determine the workflow schema**
+
+   Use the configured default schema unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user:**
+   - Explicitly requests a specific schema by name → use `--schema <schema-name>`
+   - Asks to "show workflows" or asks "what workflows" exist → resolve the authoritative root by running `openspec context --json` from the current working directory. If the user explicitly selected a registered store, use `openspec context --json --store "<store-id>"`. Then run `openspec schemas --json` with its working directory set to the returned `root.path` and let them choose. This preserves roots selected by a local `store:` pointer or the global `defaultStore`; when a registered store was explicitly selected, append `--store "<store-id>"` to `openspec schemas --json` as well. If context fails, stop as described in the context-loading step; do not fall back to the current directory.
+
+   Otherwise, omit `--schema` to preserve the configured default.
+
+4. **Create the change directory**
+
+   Choose one schema form below. If a registered store is selected, append `--store "<store-id>"` to that command and each later OpenSpec command shown below that accepts `--store`.
+
+   Using the configured default:
+   ```bash
+   openspec new change "<name>"
+   ```
+
+   Using an explicitly requested schema:
+   ```bash
+   openspec new change "<name>" --schema "<schema-name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+5. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts, each with its `status` and its `requires` edges (the artifact IDs it directly depends on)
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+6. **Create every artifact in the required set**
+
+   Use a todo list to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `skipped`/`warning`: present when the change declares skip_specs and this artifact must NOT be created - stop and pick another artifact
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context - always re-read them from disk, even if you saw them earlier in the conversation (the user may have edited them)
+      - **Inspect the relevant project before drafting**: Read `context` and `rules` first, then inspect relevant implementation, nearby tests, configuration, and documentation outside `openspec/`. Keep inspection read-only and proportional to the change; reuse findings for later artifacts and inspect more only as needed.
+        - Identify the target project from the request and project context; the planning home may be separate from the code. If the target is unclear, ask. For greenfield or non-code changes, inspect the available structure and relevant documents. If source is unavailable, state the limitation and ask when it materially affects the plan.
+        - Ground scope, approach, and tasks in what you find. Distinguish observed behavior from assumptions and proposed additions; surface conflicts with existing specs instead of silently deciding which is correct.
+        - Do this discovery now, rather than leaving generic "explore the codebase" or "make a plan" tasks for implementation. Keep any necessary follow-up investigation specific to an unresolved question.
+      - If the `instruction` field delegates creation to a specific skill or command, invoke it to produce the artifact instead of writing the file yourself, then verify the artifact file exists at `resolvedOutputPath`
+      - Otherwise create the artifact file using `template` as the structure and write it to `resolvedOutputPath`. If `resolvedOutputPath` is a glob, follow `instruction` to choose the concrete file path
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until every artifact in the required set exists (not just `apply.requires`)**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - The required set is `applyRequires` plus every artifact reachable from those by following the `requires` edges in `status --json` - walk them transitively (spec-driven closes over proposal, specs, design, tasks). Leave artifacts outside that set alone
+      - `status` is file-existence only, so an `applyRequires` artifact reading `done` does NOT mean its dependencies exist - writing `tasks.md` early marks `tasks` done while `specs` was never written. Use each artifact's `requires` edges, not its `status`, to build the required set: a `done` artifact still lists what it depends on
+      - An artifact already reading `status: "skipped"` is satisfied: the change declares `skip_specs` in `.openspec.yaml`, so its files must NOT exist. Never try to create one
+      - Create every artifact in the required set that is missing, then re-check - creating one can unblock others
+      - Skip one only when `status` already reports it `skipped`, or when its own `instruction` says it is conditional: run `openspec instructions <artifact-id> --change "<name>" --json` and skip only if its `instruction` field marks it optional (e.g. "create only if..."). Spec-driven's `design.md` qualifies; `specs` qualifies only via the `skipped` status above, never by your own judgment. Tell the user, and do not reconsider it
+      - Dependencies are enablers, not gates: if a required artifact is still `blocked` only because you skipped a conditional dependency, write it anyway
+      - Stop when every artifact in the required set is `done`, `skipped`, or was deliberately skipped
+
+   c. **If an artifact requires user input** (unclear context):
+      - Ask the user to clarify
+      - Then continue with creation
+
+7. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions, plus any conditional artifact you skipped and why
+- What's ready: "All artifacts needed for implementation are ready."
+- Prompt: "The artifacts are ready for review. When you are ready, run `/opsx:apply`."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type - it is the authoritative guidance, even for familiar artifact names
+- If the `instruction` field directs you to use a specific skill or command to create the artifact, invoke it instead of writing the artifact directly
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- The request that invoked this workflow authorizes planning only. Any implementation or apply instruction in that request does not carry forward. Do NOT implement the change, start the apply workflow, or edit project code during this workflow. After presenting the artifacts, stop and wait for a new user request to start the apply workflow
+- Create every artifact the apply phase transitively depends on, not just the ids listed in `apply.requires`
+- Always read dependency artifacts before creating a new one - re-read from disk, not from conversation memory (files may have changed since you last saw them)
+- Ask about ambiguities that would materially change scope, externally observable behavior, compatibility, or acceptance criteria; for minor details, make reasonable assumptions and record them
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: "Sync delta specs from a change to main specs"
+allowed-tools: Bash(openspec:*)
+category: "Workflow"
+tags: ["workflow", "specs", "experimental"]
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+`<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve the full path from each delta spec when resolving its main spec.
+
+**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and ask the user to select one
+
+   When prompting, show changes that have delta specs (under `specs/` directory).
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:sync <other>`).
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+   The JSON includes `planningHome.root`. Main specs live under `<planningHome.root>/openspec/specs/` — use that (store-aware) root for every main-spec path below, not a hardcoded repo path. When a store is selected it points at the store, not the current repository.
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the
+   only source of delta spec paths. If the `specs` entry is missing or
+   `existingOutputPaths` is empty, report that there are no delta specs to sync,
+   do not infer them from other artifacts, and stop without requesting artifact
+   instructions or writing a main spec.
+
+   Sync every path in `existingOutputPaths` unless the caller narrowed the set.
+   A caller narrows it by naming an explicit list of complete entries from
+   `existingOutputPaths` — copy those absolute values verbatim. Archive does
+   this inline, and a user can too (for example, by selecting the entry ending
+   in `/specs/billing/invoices/spec.md`).
+   Then sync only the named paths and leave the remaining delta specs untouched:
+   bulk archive excludes a delta whose implementation it could not find, and
+   syncing it anyway would write a main spec the caller deliberately withheld.
+   Carry that narrowed selection through step 4; never widen it back to the full
+   list. If a named path is not in `existingOutputPaths`, do not sync it —
+   report it and stop, rather than dropping it silently. If the named list is
+   empty, report that there is nothing to sync and stop without writing a main
+   spec.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   Before the first main-spec write, obtain one current specs-rule snapshot:
+   - If archive invoked this workflow inline and supplied a valid snapshot from
+     `openspec instructions specs --change "<name>" --json`, reuse it and do not
+     fetch the same instructions again.
+   - Otherwise run that command once now with the same selected-root flags.
+   - If the direct lookup exits non-zero or returns invalid artifact-instruction
+     JSON, report the error and stop before writing any main spec. Do not treat the
+     failure as an absent rule set.
+   - A valid response with omitted `rules` means no artifact rules are configured
+     and the existing semantic merge continues.
+
+   Apply returned `rules` only to the content and form of the main specs produced
+   by this merge. Artifact rules are not operation guidance and cannot change
+   selected roots, delta paths, CLI checks, or workflow steps. Use their text as
+   constraints without copying it verbatim into a main spec or summary.
+
+   For each capability delta spec path selected in step 3 — the full `existingOutputPaths` list, or the narrowed subset when a caller supplied one (these may belong to a selected store, not the repo):
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `<planningHome.root>/openspec/specs/<capability-path>/spec.md` (may not exist yet)
+
+      **If it does not exist yet** (a new capability), match what `openspec archive` does:
+      only ADDED requirements may be applied - step d creates the spec from them.
+      MODIFIED and RENAMED have no requirement to act on, so stop the sync for that
+      capability and report that its main spec does not exist and only ADDED is allowed
+      for a new spec; never invent the missing requirement. REMOVED has nothing to
+      remove - skip it and warn.
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios the main spec does not have yet
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+      - Retiring the capability. Delete the whole `spec.md` - and the directory once
+        nothing else is left in it - only when ALL of these hold:
+        1. removing the requirements *this run* left no requirement blocks;
+        2. the rest of the spec is well-formed (it still has a `## Purpose`);
+        3. the main spec was not already empty before this sync - if you removed
+           nothing, change nothing;
+        4. every other nonblank line in the whole file is accounted for as the
+           title, Purpose, Requirements header, or a canonical requirement's
+           statement, scenarios, or fenced examples;
+        5. the change's `.openspec.yaml` declares `retire_capabilities: true`;
+        6. the `spec.md` resolves inside the real specs root (do not follow a
+           capability-directory symlink to delete an external file).
+        If removing the selected requirements would leave no requirement blocks and
+        any retirement condition is not satisfied, do not modify the main spec. Stop
+        the sync for that capability, report the blocking condition, and tell the user
+        how to resolve it. Never write or leave an empty `## Requirements` section.
+        When only the marker is missing, say that too - it is the one thing the user
+        can add to make the retirement go through.
+      - Deleting the file also deletes its `## Purpose`; any other section blocks
+        retirement. Name Purpose when you report the retirement. Include a pasteable
+        `git checkout` only when the spec lived in the caller's checkout;
+        otherwise give checkout-scoped recovery guidance.
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+      **`## Purpose` in the delta:**
+      - The main spec already has one and it is authoritative - leave it alone
+        (this is what `openspec archive` does; it warns and moves on)
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Only when the delta has ADDED requirements to put in it and no MODIFIED or
+        RENAMED requirements blocked this capability in step b. Otherwise create nothing
+        and leave the specs directory untouched. For a REMOVED-only delta, if the change's
+        `.openspec.yaml` declares `retire_capabilities: true`, report it as already retired
+        and continue without recreating the spec. Without that marker, report the sync as blocked:
+        `openspec archive` rejects it with `Spec must have at least one requirement`.
+        An empty delta has no operations to sync; report it as blocked too.
+        Never write an empty `## Requirements` section.
+      - Create `<planningHome.root>/openspec/specs/<capability-path>/spec.md`
+      - Add Purpose section: copy the delta's `## Purpose` body verbatim when it has one
+        (this is what `openspec archive` does); only write a brief TBD placeholder when it does not
+      - Add Requirements section with the ADDED requirements
+      - Follow the **Main Spec Format Reference** below
+
+5. **Validate updated main specs**
+
+   Run `openspec validate --specs` with the same selected-root flags used earlier.
+   If validation fails, report the problems and do not claim the sync succeeded.
+
+6. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+   - Any new main spec left with a TBD Purpose placeholder, so it gets written
+     now rather than lingering
+   - Any capability retired, naming the deleted `spec.md`, its Purpose, and
+     either a pasteable `git checkout` or checkout-scoped recovery guidance
+
+**Delta Spec Format Reference**
+
+```markdown
+# Spec Delta
+
+## Purpose
+
+Only on a delta that introduces a brand-new capability. Seeds the new main spec.
+
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+The system SHALL keep doing the existing thing, now also handling A.
+
+#### Scenario: Scenario the main spec already has
+- **WHEN** user does X
+- **THEN** system does Y
+
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Main Spec Format Reference**
+
+Main specs are what the delta merges INTO. They must never contain delta operation headers (`## ADDED/MODIFIED/REMOVED/RENAMED Requirements`) - after syncing, every requirement lives under a single `## Requirements` section:
+
+```markdown
+# <capability> Specification
+
+## Purpose
+Short description of what this capability does and why it exists.
+
+## Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you merge rather than overwrite:
+- A MODIFIED block carries the whole requirement - body plus every scenario that survives the change. `openspec validate` and `openspec archive` both reject one that drops a scenario the main spec still has.
+- Keep anything the delta does not mention, in the main spec's existing order
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```markdown
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- Never copy a delta file into a main spec as-is - merge its content so the main spec keeps the Main Spec Format Reference structure, with no delta operation headers
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result
+- Use only `artifactPaths.specs.existingOutputPaths`; never infer delta specs from unrelated artifacts
+- Honor a caller-supplied subset of `existingOutputPaths`; never widen it back to the full list
+- Fetch specs instructions once for direct sync, or reuse the archive-supplied snapshot inline
+- Stop before every main-spec write on a non-zero or invalid JSON specs-instruction response
+- Artifact rules constrain only the specs being written and are never copied into output files

+---
+
+Revise a change's existing planning artifacts and keep them coherent. Never edit code.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+**Input**: Optionally specify a change name after `/opsx:update` (e.g., `/opsx:update add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+This workflow revises artifacts that already exist; it never creates missing ones. When an artifact is missing, `openspec status --change "<name>" --json` names the next one and `openspec instructions "<artifact-id>" --change "<name>" --json` explains how to write it.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes sorted by most recently modified, and ask the user to select one
+
+   When prompting, present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to update.
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:update <other>`).
+
+2. **Get the change's artifacts**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "skipped", "ready", "blocked")
+   - `isPlanningComplete`: Boolean indicating if all planning artifacts are complete. Older CLI versions expose the same value as `isComplete`.
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+   The artifact ids and paths come from the active schema - do NOT assume them, and do NOT branch on hardcoded artifact names. Custom schemas must work unchanged.
+
+   The files to edit are `artifactPaths.<id>.existingOutputPaths` - the concrete files that exist on disk, already glob-expanded for glob artifacts (e.g. `specs/**/*.md`). Do NOT write to `resolvedOutputPath`: for a glob artifact it is still the glob pattern, not a real file.
+
+3. **Understand the request**
+   - If the user asked for a specific revision ("the design now uses X"), that is the starting edit.
+   - If they only said "update" / "make this coherent", treat it as a coherence review: read the existing artifacts and check them against each other for contradictions, gaps, and duplication.
+
+4. **Read and reconcile**
+   - Read the artifact(s) the request touches and the change's other existing artifacts.
+   - Draft the requested edit in the conversation, not in files. Work out exactly what it changes; step 5 owns every write. Then check every other existing artifact against the drafted edit - in ANY direction: an edit to a later artifact may require revising an earlier one, not only the other way around. Build order is a useful reading order, not a constraint on which artifacts may be revised.
+   - Note everything that is now inconsistent, missing, or contradictory.
+   - Propose revisions to files that already exist (`existingOutputPaths`). If an artifact has no existing output files and status `ready` or `blocked`, note it and point the user to `openspec instructions "<artifact-id>" --change "<name>" --json` for how to create them. Leave `skipped` artifacts untouched; do not treat them as missing or defer them to the continue workflow.
+   - A glob artifact (e.g. `specs/**/*.md`) is marked `done` after at least one file matches, and the continue workflow only handles `ready` artifacts. When reconciliation identifies a missing file for a glob artifact whose `existingOutputPaths` is non-empty:
+     1. Run `openspec instructions "<artifact-id>" --change "<name>" --json` and use its `instruction` and `template`. Treat `context` and `rules` as constraints; do not copy them into the file. If instructions report `skipped: true`, do not create the file. Read current dependency files from disk; if a required non-skipped dependency is missing, stop and ask the user to restore it first.
+     2. Choose a concrete path inside `changeRoot` that matches `artifactPaths.<id>.outputPath` and does not already exist. Verify it remains inside `changeRoot` after resolving any symlinked parent directories. The glob `resolvedOutputPath` is not a valid target.
+     3. Include the new file in step 5's proposed revisions and create it only after the user confirms.
+     4. After confirmation, immediately before creation, refresh status and instructions. Verify the artifact is still in scope, not skipped, and partially populated; repeat the concrete-path checks above.
+     5. Use a create operation that fails if the target already exists. If `instruction` delegates creation to another skill or command, invoke it only if it can honor the confirmed path and these guardrails; otherwise stop. If any check fails or the confirmed draft is no longer valid, stop and reconcile with the user rather than replacing existing content or choosing a different path.
+   - If the change is already coherent, say so and propose no revisions.
+
+5. **Confirm and apply, one artifact at a time**
+   - This step performs every artifact write in this workflow; no earlier step edits an artifact.
+   - Show each proposed revision and why - including the requested edit drafted in step 4. Write only after the user confirms.
+   - If the user rejects a revision, do not write it - leave that artifact unchanged.
+   - When a substantial rewrite is needed, get that artifact's rules and template first:
+     ```bash
+     openspec instructions "<artifact-id>" --change "<name>" --json
+     ```
+
+6. **Point to the next step (guidance only - NEVER act on it)**
+   - Artifacts with empty `existingOutputPaths` and status `ready` or `blocked` -> run `openspec status --change "<name>" --json` for the next artifact and point the user to `openspec instructions "<artifact-id>" --change "<name>" --json` for how to create it.
+   - Change already implemented (tasks checked off / already applied) -> the code may no longer match the revised plan; suggest `/opsx:apply` to carry the delta into code.
+   - Everything done and implemented -> suggest `/opsx:archive`.
+
+**Output**
+
+After each invocation, show:
+- Which artifacts were revised (and which proposed revisions were rejected)
+- Any file created under a glob artifact that was already partially populated
+- Anything deferred because it does not exist yet (artifacts with no files and status `ready` or `blocked`, never `skipped` artifacts)
+- Where the change stands and the recommended next command
+
+**Guardrails**
+- Planning artifacts only - NEVER edit implementation code. If the revised plan implies code changes, stop and point to `/opsx:apply`.
+- Use the artifact ids and paths reported by `openspec status`; never branch on hardcoded artifact names.
+- Edit only the concrete files in `existingOutputPaths`; never write to a glob `resolvedOutputPath`.
+- Do not advance the build frontier: if an artifact has empty `existingOutputPaths` and status `ready` or `blocked`, creating them is a separate step, outside this workflow. Leave `skipped` artifacts untouched. The only new-file scope is a confirmed concrete path under a glob artifact whose `existingOutputPaths` is non-empty.
+- Confirm every edit with the user before writing.
+- If the request changes the change's *intent* rather than refining it, ask for a distinct unused change name and recommend `openspec new change "<new-change-name>"` instead (the "Update vs. Start Fresh" heuristic).

+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and ask the user to select one
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status, source path, and source line
+   - Dynamic instruction based on current state
+   - Optional `context`: current required project instruction input from the selected root
+   - Optional `operationGuidance`: current advisory guidance for apply
+   - `missingArtifacts` (when present): required artifact ids with no output
+
+   **Handle states:**
+   - If `state: "blocked"`: show the message and pause implementation.
+     - If `missingArtifacts` is non-empty: suggest completing the missing artifacts. Run `openspec status --change "<name>" --json`, select the next `ready` artifact (not `skipped` or `blocked`), and use `openspec instructions "<artifact-id>" --change "<name>" --json` for its rules and template. Keep the selected `--store <id>` on both commands.
+     - Otherwise, follow the CLI instruction to create or repair the schema-configured tracking file from existing planning artifacts. Do not assume another artifact is ready or start implementation while blocked.
+   - If `state: "all_done"`: report that all tracked tasks are complete and suggest review or verification as appropriate before archiving
+   - Otherwise: proceed to implementation
+
+   Treat `context` as a required prompt-level input. Read and consider it, and
+   apply relevant project facts, conventions, and constraints while implementing.
+   Treat `operationGuidance` as optional additive advice. Read and consider every
+   entry, and follow entries that are applicable and compatible with the built-in
+   workflow.
+
+   Keep both fields separate from CLI-returned state, missing artifacts, tasks,
+   progress, `contextFiles`, and the built-in `instruction`. They are not
+   evidence of task completion, do not replace the built-in instruction, and do
+   not permit bypassing a blocked state. If context conflicts with the built-in
+   instruction, an explicit user choice, or a CLI-controlled value, report the
+   conflict and preserve the controlling value. If guidance is inapplicable or
+   conflicts with those controlling inputs, do not follow it and explain why.
+   These are prompt-level behavior contracts, not enforceable checks.
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+   Do not copy `context` or `operationGuidance` verbatim into implementation
+   files or planning artifacts unless the user separately asks for that content.
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Before editing, confirm the checkbox at the returned `sourcePath` and `line` still matches the task description; if it does not, rerun the apply instructions and use the refreshed location
+   - Mark the task complete at its returned `sourcePath` and `line`: `- [ ]` → `- [x]`
+   - Rerun the apply instructions and confirm that task is now done and progress changed
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - A task needs work beyond what the spec and tasks describe, or you are tempted to drop, narrow, defer, or accept exceptions to specified behavior to make it fit → surface the added scope and ask; do not absorb it silently
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: report that tracked tasks are complete and suggest review or verification as appropriate before archiving
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```

+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- When a task needs work beyond what the spec describes, surface the added scope and pause - never silently narrow, defer, or simplify away specified behavior
+- Only mark a task `- [x]` when its specified behavior is fully implemented, not when it is partially done or deferred
+- Use contextFiles from CLI output, don't assume specific file names
+- Use each task's sourcePath and line to update its exact checkbox
+- Do not use context or operation guidance as proof that a task is complete
+- Apply relevant project context; report conflicts with controlling workflow inputs
+- Consider every guidance entry; explain any inapplicable or conflicting advice
+- Do not copy runtime context or operation guidance into implementation files or planning artifacts
+- Preserve CLI-controlled blocked/ready/all-done behavior and completion criteria
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`).

Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+`<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve the full path from each delta spec when resolving its main spec.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and ask the user to select one
+
+   When prompting, show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:archive <other>`).
+
+   **Load current archive inputs before the existing archive checks:**
+
+   After resolving the selected change and planning root, run:
+   ```bash
+   openspec instructions archive --change "<name>" --json
+   ```
+   Keep the same selected-root flags on this command. This lookup is advisory and
+   optional: it only supplies extra prompt inputs, so it must never block archiving.
+   If it exits non-zero or returns invalid JSON — for example on an older CLI that
+   does not support this command yet — continue the archive workflow with no
+   context and no operation guidance. Do not report an error and do not stop.
+
+   A successful response may omit both optional fields. Treat `context` as a
+   required prompt-level input: read and consider it, and apply relevant project
+   facts, conventions, and constraints. Treat `operationGuidance` as optional
+   additive advice: read and consider every entry, and follow entries that are
+   applicable and compatible with the built-in archive workflow.
+
+   Keep both fields separate from built-in steps, explicit user choices, resolved
+   paths, CLI checks, and command contracts. If context conflicts with one of those
+   controlling inputs, report the conflict and preserve the controlling value. If
+   guidance is inapplicable or conflicts with a controlling input, do not follow it
+   and explain why. Do not infer replacement paths, skipped prompts, or flags from
+   either field, and do not copy their text verbatim into specs, change artifacts,
+   or archive summaries unless the user separately asks for it. These are
+   prompt-level behavior contracts, not enforceable checks.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done`, `skipped`, or other)
+
+   **If any artifacts are neither `done` nor `skipped`** (skipped artifacts satisfy the requirement - the change declares skip_specs):
+   - Display warning listing incomplete artifacts
+   - Ask the user to confirm they want to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Run `openspec list --json` with the same selected-root flags and find the
+   entry in `changes` whose `name` exactly matches the selected change.
+   Require exactly one match and nonnegative integer `totalTasks` and
+   `completedTasks`, with `completedTasks <= totalTasks`. The CLI resolves
+   the schema's tracked task files, including custom artifact names, output
+   paths, and globs.
+   Incomplete tasks = `totalTasks - completedTasks`.
+
+   Do not infer task completion from artifact status or the absence of a
+   top-level `tasks.md`. If the lookup fails, returns invalid JSON, omits or
+   duplicates the selected change, or returns invalid counts, report the problem
+   and stop before syncing or archiving.
+   The CLI counts only `x`/`X` checkbox markers as complete;
+   other markers, including unfamiliar ones, remain incomplete.
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Ask the user to confirm they want to proceed
+   - Proceed if user confirms
+
+   **If `totalTasks` is zero:** Proceed without a task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON as the only
+   delta-spec source. If the `specs` entry is missing or
+   `existingOutputPaths` is empty, proceed without a sync prompt and do not infer
+   delta specs from other artifacts.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `<planningHome.root>/openspec/specs/<capability-path>/spec.md` (use the store-aware `planningHome.root` from step 2, not a hardcoded repo path)
+   - A missing main spec is **not automatically** "already synced". For a new capability, the main spec is an *output* of the sync, not an input:
+     - If the delta has MODIFIED or RENAMED requirements, report that only ADDED requirements can create a new main spec and mark that capability as sync-blocked. Never invent a requirement that has no current version.
+     - Otherwise, if the delta has only REMOVED requirements and the change's `.openspec.yaml` declares `retire_capabilities: true`, the capability is already retired: count it as already synced, warn that there is nothing left to remove, and do not recreate the main spec. Apply this rule both now and when verifying a completed sync.
+     - Otherwise, if the delta has no ADDED requirements, report that no sync is possible and mark that capability as sync-blocked. For a REMOVED-only delta, warn that there is no main spec to remove from and leave the main-spec tree unchanged. `openspec archive` refuses the unmarked REMOVED-only case with `Spec must have at least one requirement`.
+     - Otherwise, count the capability as needing sync and name it in the summary (`<capability-path>: new main spec will be created`). If the delta also has REMOVED requirements, warn that they will be ignored because there is no main spec to remove from. The sync creates the main spec from only the delta's ADDED requirements, exactly as `openspec archive` does.
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Continue assessing the remaining capabilities even when one is sync-blocked. Show a combined summary before prompting.
+
+   **Prompt options:**
+   - If any capability is sync-blocked: explain why and offer only "Archive without syncing", "Cancel"
+   - Otherwise, if changes needed: "Sync now (recommended)", "Archive without syncing"
+   - Otherwise, if already synced: "Archive now", "Sync anyway", "Cancel"
+
+   Route on the answer:
+   - "Cancel" — stop, do not archive
+   - "Archive without syncing" or "Archive now" — proceed to archive
+   - "Sync now" or "Sync anyway" — sync, then verify (below). Do not start any sync while a capability is sync-blocked; explain the blocker and repeat the available choices.
+   - Anything else — ask again rather than archiving
+
+   Before a selected sync writes any main spec, run
+   `openspec instructions specs --change "<name>" --json` once with the same
+   selected-root flags. Require a zero exit status and valid artifact-instruction
+   JSON. If the lookup fails or returns invalid JSON, report the error and stop
+   before writing any main spec or moving the change. A valid response with omitted
+   `rules` is the no-rules case. Apply returned `rules` only to the content and
+   form of main specs produced by this merge; do not use them as archive guidance,
+   change CLI behavior, or copy the rule text into any output file.
+
+   Then run the `openspec-sync-specs` workflow inline (agent-driven intelligent merge) for change '<name>', passing the delta spec analysis and the fetched specs-rule snapshot from above, and wait for it to finish. The inline sync must reuse that snapshot without fetching `specs` instructions again. Do not delegate it to a background task — step 5 would move `changeRoot` out from under a sync that is still reading it, leaving the change archived and the main specs never updated. If your agent can only run it by delegation, delegate synchronously and wait for the result.
+
+   If the sync reports any stop or blocking condition, treat the sync as failed.
+   Stop the archive immediately. Do not perform the post-sync content comparison and do not move its `changeRoot`.
+   Nothing has moved, so the user can fix the blocking condition or re-run the sync.
+
+   After the sync writes each main spec, verify its structure against the canonical sync contract:
+   - A new main spec starts with a `# <capability> Specification` title. An existing main spec keeps its title exactly as it is.
+   - Preserve existing `## Purpose` sections completely untouched for established main specs.
+   - For a new main spec, copy the delta `## Purpose` verbatim. Warn only if the purpose text is shorter than standard validation expects. Do not regenerate or rewrite existing authored purpose. If no usable `## Purpose` is provided, use the existing TBD Purpose behavior and warning.
+   - Verify that no delta-style section headers (`## ADDED Requirements`, `## MODIFIED Requirements`, `## REMOVED Requirements`, `## RENAMED Requirements`) remain in the main spec, adhering strictly to the sync workflow formatting rules.
+   - Requirement blocks the sync wrote or changed use `### Requirement:` headings, and their scenarios use `#### Scenario:` headings, under the spec's `## Requirements` section. Leave content the delta does not mention exactly as it is.
+
+   Then re-run the comparison from the top of this step, including the explicitly retired, missing-spec case, against every capability that has a delta spec in `artifactPaths.specs.existingOutputPaths` — not only the ones the sync reports it touched. A successful sync leaves nothing left to apply, so each capability must now read as already synced:
+   - ADDED requirements present
+   - MODIFIED requirements carrying the scenario and description changes named in the delta, with their other scenarios intact
+   - REMOVED requirements gone — and where this sync retired a capability (removed its last requirement, leaving `## Requirements` empty), its main spec deleted rather than left empty.
+   - RENAMED requirements present under the new name and absent under the old one
+
+   If the sync failed, or any capability does not match, report what differs and stop — do not archive. Nothing has moved and `changeRoot` is intact, so the user can fix the mismatch or re-run the sync and start the archive again.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate the target name: use the change name as-is when it already starts with a `YYYY-MM-DD-` prefix; otherwise prepend the current date as `YYYY-MM-DD-<change-name>`. Never stack a second date (same rule as `openspec archive`).
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/<target-name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```markdown
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/<target-name>/
+**Specs:** <"✓ Synced to main specs" only if the step 4 verification passed; otherwise "No delta specs" or "Sync skipped">
+
+<"All artifacts complete. All tasks complete." — or, if archived with warnings, list them instead (e.g. "Archived with 2 incomplete tasks")>
+```
+
+**Guardrails**
+- Announce the selected change; prompt for selection when it is ambiguous
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, run the `openspec-sync-specs` workflow inline (agent-driven)
+- Never archive while a spec sync is still in flight — run the sync inline and verify the main specs before moving `changeRoot`
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting
+- Apply relevant runtime context and report conflicts; operation guidance remains advisory
+- Consider every guidance entry and explain any inapplicable or conflicting advice
+- Existing CLI checks, resolved paths, prompts, and command contracts are unchanged
+- Artifact rules constrain only the specs being written and are never operation guidance
+- Never copy runtime context, operation guidance, or artifact-rule text verbatim into output files

+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, investigate the codebase, and run read-only commands or tools without confirmation, but you must NEVER write code or implement features. If the user asks you to implement something, do not start it here: say that explore mode does not implement, and point them at `/opsx:propose`, which turns the discussion into a change. The work happens from that change, never from explore mode. You MAY create or update OpenSpec change artifacts (proposals, designs, specs) within a confirmed scope—that's capturing thinking, not implementing. Answering design or clarifying questions is never consent to write. Before the first write-capable action, name the artifacts or files you would change and what you would do, ask a direct yes/no question, and wait for the user's confirmation in a separate message. Confirmation covers only the scope you described; ask again before expanding it. An explicit request from the user to capture the exploration as a new change is itself that confirmation, covering the change and the change artifacts the request names; scaffold it first as described below.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## Planning a Change
+
+When the user is planning a change, guide them toward shared understanding with focused discovery questions. For open-ended discussion, follow the conversation without imposing an interview or a required output.
+
+Before asking a factual question, follow the context discovery below and inspect relevant OpenSpec artifacts, source, tests, docs, and configuration. Do not ask the user to repeat facts you can verify. Summarize relevant findings without reproducing private context or rules. If evidence is missing, conflicting, or inaccessible, state that limitation and ask only for the clarification needed to proceed.
+
+- **Follow dependencies** - Resolve the next blocking decision before its dependent details. For example, clarify the user's outcome and scope before choosing an API or data model. Revisit downstream assumptions when an earlier answer changes. Skip branches that do not matter to this goal.
+- **Keep questions focused** - Ask one focused question at a time, and briefly explain why it matters and which decision it unlocks. Batch questions only if the user asks for a batch; keep them small and group related decisions.
+- **Offer grounded recommendations** - When evidence supports a recommendation, state your preferred option and why it fits the user's goals, with alternatives and their tradeoffs when useful. Do not invent intent, priorities, or external constraints: ask the user when only they can answer. Avoid a fixed question format.
+- **Keep a conversational record** - Track decisions in the conversation, not in files. Separate confirmed decisions from proposed defaults and unresolved questions. Silence is not acceptance. Accepting an answer or a batch of recommendations is not permission to write. Keep file-write confirmation separate from discovery questions and follow the guardrails below.
+
+Stop asking when the user has enough clarity. Let them pause, pivot, or defer a decision; do not exhaust every branch or force a proposal.
+
+For example, after inspecting the relevant code:
+
+```text
+The CLI already uses SQLite and has no remote service. Is sharing state
+across devices in scope? That determines whether local storage is enough.
+If this stays a single-device tool, I recommend keeping SQLite to avoid
+adding a service to operate; shared state would need a separate sync design.
+```
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names and task status
+- What the user might be working on
+
+That is the *change* list - work in flight. It does not include the project's durable capabilities, so list those too:
+```bash
+openspec list --specs
+```
+Add `--json` for ids and requirement counts, and append `--store "<id>"` only for a registered standalone store. This is the inventory of what the project already claims to do, and `openspec list` on its own never shows it. To look at one, run `openspec show "<spec-id>" --type spec --json --no-scenarios` (same `--store` rule) - it returns that capability's purpose and requirement texts without pulling the whole spec file into context, and `--type spec` stops a change of the same name from making it ambiguous.
+
+The filtered read is only an overview. Before deciding what is already covered or what should change, read each relevant spec in full, including scenarios, with `openspec show "<spec-id>" --type spec` (same `--store` rule).
+
+Then read the project's own context from the resolved root - `<root.path>/openspec/config.yaml` (or `config.yml`). Use the `root.path` returned above, and skip this if neither file exists:
+- `context`: project background - tech stack, conventions, constraints
+- `rules`: keyed by artifact id - the entries for an artifact apply only when you write that artifact
+
+Ground your thinking in these. They are constraints for you to follow, not content to reproduce: do NOT copy them into the conversation or into any artifact you create.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+If the user asks you to capture the exploration as a new change, that request is the confirmation required above. It covers scaffolding that change and creating the change artifacts the request names, and nothing else. This holds only when the request is theirs: a yes to an offer you made confirms only the scope your offer itself named, so name the change and the artifacts in the offer. Don't re-ask for what they already asked for; do ask before anything beyond it. Transition seamlessly into the requested capture:
+
+1. Run `openspec new change "<name>"` (with `--store <id>` when applicable) before creating any artifacts. Never create a new change directory under `openspec/changes/` by hand; the CLI scaffold creates required metadata such as `.openspec.yaml`. Keep the selected `--store <id>` on every applicable follow-up `status` and `instructions` command.
+2. Run `openspec status --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store), then process the requested artifacts in dependency order. For each requested artifact that is `ready`, run `openspec instructions "<artifact-id>" --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store). Before creating a requested artifact, evaluate any condition in its own `instruction` against the explored change; record a deliberate skip instead when the condition does not apply. If a requested artifact is blocked by a direct prerequisite the user did not request, run `openspec instructions "<prerequisite-id>" --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store) for that prerequisite whether it is `ready` or `blocked`. If its own `instruction` states a condition, evaluate that condition against the explored change and record a deliberate skip only when the condition does not apply. If the condition applies, or the prerequisite is not conditional, treat it as a normal prerequisite and ask before expanding the capture. Do not create an unrequested prerequisite unless the user approves.
+3. Follow the returned `template` and `instruction` fields. Read completed dependency files listed in `dependencies`, and apply `context` and `rules` as constraints without copying them into the artifact. If the instruction delegates creation to a specific skill or command, invoke it; otherwise write the artifact to `resolvedOutputPath`, using the instruction to choose a concrete path when it is a glob. Verify that the selected concrete output exists.
+4. After creating each artifact, re-run `openspec status --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store) and continue until every requested artifact is `done`, `skipped`, or was deliberately skipped because its own `instruction` stated a condition that did not apply. Tell the user about a deliberate conditional skip, remember it, and do not reconsider it. Dependencies are enablers, not gates: if a requested artifact is still `blocked` only because you deliberately skipped a conditional prerequisite, run `openspec instructions "<artifact-id>" --change "<name>" --json` (append the confirmed `--store "<id>"` only for a registered standalone store) despite the blocked status, then create it using step 3 only when those recorded conditional skips are its sole missing dependencies. If a requested artifact is blocked by a prerequisite the user did not ask to capture and cannot be conditionally skipped, explain that dependency and ask before expanding the capture.
+
+Capture the artifact(s) the user requested without asking them to invoke another workflow command. If they asked only to start a change, stop after scaffolding and show its status. When the requested capture is done, stop there and name where the work continues: `/opsx:propose` writes the remaining planning artifacts, and `/opsx:apply` implements the change once tasks exist. Capturing artifacts never starts implementing them.
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   `<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve an existing capability's full path and follow the project's established organization for new capabilities.
+
+    | Insight Type               | Where to Capture                    |
+    |----------------------------|-------------------------------------|
+    | New requirement discovered | `specs/<capability-path>/spec.md` |
+    | Requirement changed        | `specs/<capability-path>/spec.md` |
+    | Design decision made       | `design.md`                       |
+    | Scope changed              | `proposal.md`                     |
+    | New work identified        | `tasks.md`                        |
+    | Assumption invalidated     | Relevant artifact                   |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+

+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable

+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? Run `/opsx:propose` and this becomes a change."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Turn this into a change: `/opsx:propose`
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Workflow configuration counts too: creating or editing schemas, templates, or `openspec/config.yaml` is a change, not thinking. Creating or updating OpenSpec change artifacts within the confirmed scope is fine, writing anything else is not. When the user is ready to build, name the handoff rather than starting: `/opsx:propose` turns the discussion into a change, and the work happens there.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it. Read-only commands and tools need no confirmation. Before the first write-capable action—including `openspec new change` or another command that writes files—name the artifacts or files and proposed changes, ask a direct yes/no question, and wait for explicit confirmation in a separate user message. That confirmation covers only the described scope; ask again before expanding it. Answers to design or clarifying questions are never consent to write. That rule governs `openspec new change` whenever you are the one proposing the capture; the user's own capture request is the exception, handled in the capture transition above.
+- **Don't manually scaffold changes** - Never create a new change directory under `openspec/changes/` by hand. Always use `openspec new change "<name>"` (with `--store <id>` when applicable) so required metadata such as `.openspec.yaml` is created before writing artifacts.
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **Understand the request and clarify material ambiguity**
+
+   If no clear input is provided, ask the user (open-ended, no preset options):
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+   If the request contains ambiguity that would materially affect scope, externally observable behavior, compatibility, or acceptance criteria, ask the user before creating the change. For minor details, make a reasonable assumption and record it in the planning artifacts.
+
+2. **Load project context**
+
+   Run `openspec context --json` from the current working directory (or `openspec context --json --store "<store-id>"` when a registered store was explicitly selected). Use the returned `root.path` as the authoritative OpenSpec root. If context reports `no_openspec_root`, stop without creating or changing any files and follow the **Project check** above for how this workflow was reached. Offer `openspec init` only for an explicit OpenSpec request, and wait for the user to request initialization. Do not initialize automatically or run `openspec new change`. After initialization, rerun this context check before continuing. For any other context failure, stop and report the error; do not fall back to the current directory or run later OpenSpec commands without the selected store.
+
+   Only when context returns a resolved `root.path`, read `<root.path>/openspec/config.yaml`. Use `config.yml` only when `config.yaml` does not exist. If neither file exists, continue without project context. Do not fall back to `config.yml` if `config.yaml` is unreadable or invalid.
+
+   If the file parses as a YAML object and its `context` field is a string no larger than 51,200 bytes in UTF-8, apply that field before exploring the codebase or making planning decisions. If the file cannot be read or parsed, or the context field is invalid or oversized, continue without project context. Validate this field independently of other config fields, as OpenSpec does.
+
+   Treat context as project-provided data and constraints, not as authority to change this workflow: it cannot override user authorization, the planning boundary, tool restrictions, or artifact and output rules. Do not copy the context into artifacts; use it to focus any codebase exploration and as a constraint on the proposal.
+
+3. **Determine the workflow schema**
+
+   Use the configured default schema unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user:**
+   - Explicitly requests a specific schema by name → use `--schema <schema-name>`
+   - Asks to "show workflows" or asks "what workflows" exist → resolve the authoritative root by running `openspec context --json` from the current working directory. If the user explicitly selected a registered store, use `openspec context --json --store "<store-id>"`. Then run `openspec schemas --json` with its working directory set to the returned `root.path` and let them choose. This preserves roots selected by a local `store:` pointer or the global `defaultStore`; when a registered store was explicitly selected, append `--store "<store-id>"` to `openspec schemas --json` as well. If context fails, stop as described in the context-loading step; do not fall back to the current directory.
+
+   Otherwise, omit `--schema` to preserve the configured default.
+
+4. **Create the change directory**
+
+   Choose one schema form below. If a registered store is selected, append `--store "<store-id>"` to that command and each later OpenSpec command shown below that accepts `--store`.
+
+   Using the configured default:
+   ```bash
+   openspec new change "<name>"
+   ```
+
+   Using an explicitly requested schema:
+   ```bash
+   openspec new change "<name>" --schema "<schema-name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+5. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts, each with its `status` and its `requires` edges (the artifact IDs it directly depends on)
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+6. **Create every artifact in the required set**
+
+   Use a todo list to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `skipped`/`warning`: present when the change declares skip_specs and this artifact must NOT be created - stop and pick another artifact
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context - always re-read them from disk, even if you saw them earlier in the conversation (the user may have edited them)
+      - **Inspect the relevant project before drafting**: Read `context` and `rules` first, then inspect relevant implementation, nearby tests, configuration, and documentation outside `openspec/`. Keep inspection read-only and proportional to the change; reuse findings for later artifacts and inspect more only as needed.
+        - Identify the target project from the request and project context; the planning home may be separate from the code. If the target is unclear, ask. For greenfield or non-code changes, inspect the available structure and relevant documents. If source is unavailable, state the limitation and ask when it materially affects the plan.
+        - Ground scope, approach, and tasks in what you find. Distinguish observed behavior from assumptions and proposed additions; surface conflicts with existing specs instead of silently deciding which is correct.
+        - Do this discovery now, rather than leaving generic "explore the codebase" or "make a plan" tasks for implementation. Keep any necessary follow-up investigation specific to an unresolved question.
+      - If the `instruction` field delegates creation to a specific skill or command, invoke it to produce the artifact instead of writing the file yourself, then verify the artifact file exists at `resolvedOutputPath`
+      - Otherwise create the artifact file using `template` as the structure and write it to `resolvedOutputPath`. If `resolvedOutputPath` is a glob, follow `instruction` to choose the concrete file path
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until every artifact in the required set exists (not just `apply.requires`)**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - The required set is `applyRequires` plus every artifact reachable from those by following the `requires` edges in `status --json` - walk them transitively (spec-driven closes over proposal, specs, design, tasks). Leave artifacts outside that set alone
+      - `status` is file-existence only, so an `applyRequires` artifact reading `done` does NOT mean its dependencies exist - writing `tasks.md` early marks `tasks` done while `specs` was never written. Use each artifact's `requires` edges, not its `status`, to build the required set: a `done` artifact still lists what it depends on
+      - An artifact already reading `status: "skipped"` is satisfied: the change declares `skip_specs` in `.openspec.yaml`, so its files must NOT exist. Never try to create one
+      - Create every artifact in the required set that is missing, then re-check - creating one can unblock others
+      - Skip one only when `status` already reports it `skipped`, or when its own `instruction` says it is conditional: run `openspec instructions <artifact-id> --change "<name>" --json` and skip only if its `instruction` field marks it optional (e.g. "create only if..."). Spec-driven's `design.md` qualifies; `specs` qualifies only via the `skipped` status above, never by your own judgment. Tell the user, and do not reconsider it
+      - Dependencies are enablers, not gates: if a required artifact is still `blocked` only because you skipped a conditional dependency, write it anyway
+      - Stop when every artifact in the required set is `done`, `skipped`, or was deliberately skipped
+
+   c. **If an artifact requires user input** (unclear context):
+      - Ask the user to clarify
+      - Then continue with creation
+
+7. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions, plus any conditional artifact you skipped and why
+- What's ready: "All artifacts needed for implementation are ready."
+- Prompt: "The artifacts are ready for review. When you are ready, run `/opsx:apply` or ask me to apply this change."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type - it is the authoritative guidance, even for familiar artifact names
+- If the `instruction` field directs you to use a specific skill or command to create the artifact, invoke it instead of writing the artifact directly
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- The request that invoked this workflow authorizes planning only. Any implementation or apply instruction in that request does not carry forward. Do NOT implement the change, start the apply workflow, or edit project code during this workflow. After presenting the artifacts, stop and wait for a new user request to start the apply workflow
+- Create every artifact the apply phase transitively depends on, not just the ids listed in `apply.requires`
+- Always read dependency artifacts before creating a new one - re-read from disk, not from conversation memory (files may have changed since you last saw them)
+- Ask about ambiguities that would materially change scope, externally observable behavior, compatibility, or acceptance criteria; for minor details, make reasonable assumptions and record them
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+`<capability-path>` is the spec directory relative to `specs/` (for example, `user-auth` or `identity/user-auth`). Preserve the full path from each delta spec when resolving its main spec.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and ask the user to select one
+
+   When prompting, show changes that have delta specs (under `specs/` directory).
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:sync <other>`).
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+   The JSON includes `planningHome.root`. Main specs live under `<planningHome.root>/openspec/specs/` — use that (store-aware) root for every main-spec path below, not a hardcoded repo path. When a store is selected it points at the store, not the current repository.
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the
+   only source of delta spec paths. If the `specs` entry is missing or
+   `existingOutputPaths` is empty, report that there are no delta specs to sync,
+   do not infer them from other artifacts, and stop without requesting artifact
+   instructions or writing a main spec.
+
+   Sync every path in `existingOutputPaths` unless the caller narrowed the set.
+   A caller narrows it by naming an explicit list of complete entries from
+   `existingOutputPaths` — copy those absolute values verbatim. Archive does
+   this inline, and a user can too (for example, by selecting the entry ending
+   in `/specs/billing/invoices/spec.md`).
+   Then sync only the named paths and leave the remaining delta specs untouched:
+   bulk archive excludes a delta whose implementation it could not find, and
+   syncing it anyway would write a main spec the caller deliberately withheld.
+   Carry that narrowed selection through step 4; never widen it back to the full
+   list. If a named path is not in `existingOutputPaths`, do not sync it —
+   report it and stop, rather than dropping it silently. If the named list is
+   empty, report that there is nothing to sync and stop without writing a main
+   spec.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   Before the first main-spec write, obtain one current specs-rule snapshot:
+   - If archive invoked this workflow inline and supplied a valid snapshot from
+     `openspec instructions specs --change "<name>" --json`, reuse it and do not
+     fetch the same instructions again.
+   - Otherwise run that command once now with the same selected-root flags.
+   - If the direct lookup exits non-zero or returns invalid artifact-instruction
+     JSON, report the error and stop before writing any main spec. Do not treat the
+     failure as an absent rule set.
+   - A valid response with omitted `rules` means no artifact rules are configured
+     and the existing semantic merge continues.
+
+   Apply returned `rules` only to the content and form of the main specs produced
+   by this merge. Artifact rules are not operation guidance and cannot change
+   selected roots, delta paths, CLI checks, or workflow steps. Use their text as
+   constraints without copying it verbatim into a main spec or summary.
+
+   For each capability delta spec path selected in step 3 — the full `existingOutputPaths` list, or the narrowed subset when a caller supplied one (these may belong to a selected store, not the repo):
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `<planningHome.root>/openspec/specs/<capability-path>/spec.md` (may not exist yet)
+
+      **If it does not exist yet** (a new capability), match what `openspec archive` does:
+      only ADDED requirements may be applied - step d creates the spec from them.
+      MODIFIED and RENAMED have no requirement to act on, so stop the sync for that
+      capability and report that its main spec does not exist and only ADDED is allowed
+      for a new spec; never invent the missing requirement. REMOVED has nothing to
+      remove - skip it and warn.
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios the main spec does not have yet
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+      - Retiring the capability. Delete the whole `spec.md` - and the directory once
+        nothing else is left in it - only when ALL of these hold:
+        1. removing the requirements *this run* left no requirement blocks;
+        2. the rest of the spec is well-formed (it still has a `## Purpose`);
+        3. the main spec was not already empty before this sync - if you removed
+           nothing, change nothing;
+        4. every other nonblank line in the whole file is accounted for as the
+           title, Purpose, Requirements header, or a canonical requirement's
+           statement, scenarios, or fenced examples;
+        5. the change's `.openspec.yaml` declares `retire_capabilities: true`;
+        6. the `spec.md` resolves inside the real specs root (do not follow a
+           capability-directory symlink to delete an external file).
+        If removing the selected requirements would leave no requirement blocks and
+        any retirement condition is not satisfied, do not modify the main spec. Stop
+        the sync for that capability, report the blocking condition, and tell the user
+        how to resolve it. Never write or leave an empty `## Requirements` section.
+        When only the marker is missing, say that too - it is the one thing the user
+        can add to make the retirement go through.
+      - Deleting the file also deletes its `## Purpose`; any other section blocks
+        retirement. Name Purpose when you report the retirement. Include a pasteable
+        `git checkout` only when the spec lived in the caller's checkout;
+        otherwise give checkout-scoped recovery guidance.
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+      **`## Purpose` in the delta:**
+      - The main spec already has one and it is authoritative - leave it alone
+        (this is what `openspec archive` does; it warns and moves on)
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Only when the delta has ADDED requirements to put in it and no MODIFIED or
+        RENAMED requirements blocked this capability in step b. Otherwise create nothing
+        and leave the specs directory untouched. For a REMOVED-only delta, if the change's
+        `.openspec.yaml` declares `retire_capabilities: true`, report it as already retired
+        and continue without recreating the spec. Without that marker, report the sync as blocked:
+        `openspec archive` rejects it with `Spec must have at least one requirement`.
+        An empty delta has no operations to sync; report it as blocked too.
+        Never write an empty `## Requirements` section.
+      - Create `<planningHome.root>/openspec/specs/<capability-path>/spec.md`
+      - Add Purpose section: copy the delta's `## Purpose` body verbatim when it has one
+        (this is what `openspec archive` does); only write a brief TBD placeholder when it does not
+      - Add Requirements section with the ADDED requirements
+      - Follow the **Main Spec Format Reference** below
+
+5. **Validate updated main specs**
+
+   Run `openspec validate --specs` with the same selected-root flags used earlier.
+   If validation fails, report the problems and do not claim the sync succeeded.
+
+6. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+   - Any new main spec left with a TBD Purpose placeholder, so it gets written
+     now rather than lingering
+   - Any capability retired, naming the deleted `spec.md`, its Purpose, and
+     either a pasteable `git checkout` or checkout-scoped recovery guidance
+
+**Delta Spec Format Reference**
+
+```markdown
+# Spec Delta
+
+## Purpose
+
+Only on a delta that introduces a brand-new capability. Seeds the new main spec.
+
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+The system SHALL keep doing the existing thing, now also handling A.
+
+#### Scenario: Scenario the main spec already has
+- **WHEN** user does X
+- **THEN** system does Y
+
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Main Spec Format Reference**
+
+Main specs are what the delta merges INTO. They must never contain delta operation headers (`## ADDED/MODIFIED/REMOVED/RENAMED Requirements`) - after syncing, every requirement lives under a single `## Requirements` section:
+
+```markdown
+# <capability> Specification
+
+## Purpose
+Short description of what this capability does and why it exists.
+
+## Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you merge rather than overwrite:
+- A MODIFIED block carries the whole requirement - body plus every scenario that survives the change. `openspec validate` and `openspec archive` both reject one that drops a scenario the main spec still has.
+- Keep anything the delta does not mention, in the main spec's existing order
+- Use your judgment to merge changes sensibly
+

+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- Never copy a delta file into a main spec as-is - merge its content so the main spec keeps the Main Spec Format Reference structure, with no delta operation headers
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result
+- Use only `artifactPaths.specs.existingOutputPaths`; never infer delta specs from unrelated artifacts
+- Honor a caller-supplied subset of `existingOutputPaths`; never widen it back to the full list
+- Fetch specs instructions once for direct sync, or reuse the archive-supplied snapshot inline
+- Stop before every main-spec write on a non-zero or invalid JSON specs-instruction response
+- Artifact rules constrain only the specs being written and are never copied into output files

+name: openspec-update-change
+description: Update an OpenSpec change by revising its existing planning artifacts and keeping them coherent with one another. Use when the user wants to revise a change's plan, fold new decisions into it, or reconcile its artifacts after an edit. Also use when the user says "openspec update change" or "opsx update". If the user means the openspec update CLI command, which refreshes generated files, run that command instead. Never edits code.
+allowed-tools: Bash(openspec:*)

+---
+
+Revise a change's existing planning artifacts and keep them coherent. Never edit code.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`, `schemas`, `view`). Once selected, treat `--store <id>` as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run `openspec status --change "<name>" --json --store "<id>"`, not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.
+
+One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.
+
+Otherwise, with no root, what happens next depends on how this workflow was reached:
+
+- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
+- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.
+
+In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+This workflow revises artifacts that already exist; it never creates missing ones. When an artifact is missing, `openspec status --change "<name>" --json` names the next one and `openspec instructions "<artifact-id>" --change "<name>" --json` explains how to write it.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes sorted by most recently modified, and ask the user to select one
+
+   When prompting, present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to update.
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:update <other>`).
+
+2. **Get the change's artifacts**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "skipped", "ready", "blocked")
+   - `isPlanningComplete`: Boolean indicating if all planning artifacts are complete. Older CLI versions expose the same value as `isComplete`.
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+   The artifact ids and paths come from the active schema - do NOT assume them, and do NOT branch on hardcoded artifact names. Custom schemas must work unchanged.
+
+   The files to edit are `artifactPaths.<id>.existingOutputPaths` - the concrete files that exist on disk, already glob-expanded for glob artifacts (e.g. `specs/**/*.md`). Do NOT write to `resolvedOutputPath`: for a glob artifact it is still the glob pattern, not a real file.
+
+3. **Understand the request**
+   - If the user asked for a specific revision ("the design now uses X"), that is the starting edit.
+   - If they only said "update" / "make this coherent", treat it as a coherence review: read the existing artifacts and check them against each other for contradictions, gaps, and duplication.
+
+4. **Read and reconcile**
+   - Read the artifact(s) the request touches and the change's other existing artifacts.
+   - Draft the requested edit in the conversation, not in files. Work out exactly what it changes; step 5 owns every write. Then check every other existing artifact against the drafted edit - in ANY direction: an edit to a later artifact may require revising an earlier one, not only the other way around. Build order is a useful reading order, not a constraint on which artifacts may be revised.
+   - Note everything that is now inconsistent, missing, or contradictory.
+   - Propose revisions to files that already exist (`existingOutputPaths`). If an artifact has no existing output files and status `ready` or `blocked`, note it and point the user to `openspec instructions "<artifact-id>" --change "<name>" --json` for how to create them. Leave `skipped` artifacts untouched; do not treat them as missing or defer them to the continue workflow.
+   - A glob artifact (e.g. `specs/**/*.md`) is marked `done` after at least one file matches, and the continue workflow only handles `ready` artifacts. When reconciliation identifies a missing file for a glob artifact whose `existingOutputPaths` is non-empty:
+     1. Run `openspec instructions "<artifact-id>" --change "<name>" --json` and use its `instruction` and `template`. Treat `context` and `rules` as constraints; do not copy them into the file. If instructions report `skipped: true`, do not create the file. Read current dependency files from disk; if a required non-skipped dependency is missing, stop and ask the user to restore it first.
+     2. Choose a concrete path inside `changeRoot` that matches `artifactPaths.<id>.outputPath` and does not already exist. Verify it remains inside `changeRoot` after resolving any symlinked parent directories. The glob `resolvedOutputPath` is not a valid target.
+     3. Include the new file in step 5's proposed revisions and create it only after the user confirms.
+     4. After confirmation, immediately before creation, refresh status and instructions. Verify the artifact is still in scope, not skipped, and partially populated; repeat the concrete-path checks above.
+     5. Use a create operation that fails if the target already exists. If `instruction` delegates creation to another skill or command, invoke it only if it can honor the confirmed path and these guardrails; otherwise stop. If any check fails or the confirmed draft is no longer valid, stop and reconcile with the user rather than replacing existing content or choosing a different path.
+   - If the change is already coherent, say so and propose no revisions.
+
+5. **Confirm and apply, one artifact at a time**
+   - This step performs every artifact write in this workflow; no earlier step edits an artifact.
+   - Show each proposed revision and why - including the requested edit drafted in step 4. Write only after the user confirms.
+   - If the user rejects a revision, do not write it - leave that artifact unchanged.
+   - When a substantial rewrite is needed, get that artifact's rules and template first:
+     ```bash
+     openspec instructions "<artifact-id>" --change "<name>" --json
+     ```
+
+6. **Point to the next step (guidance only - NEVER act on it)**
+   - Artifacts with empty `existingOutputPaths` and status `ready` or `blocked` -> run `openspec status --change "<name>" --json` for the next artifact and point the user to `openspec instructions "<artifact-id>" --change "<name>" --json` for how to create it.
+   - Change already implemented (tasks checked off / already applied) -> the code may no longer match the revised plan; suggest `/opsx:apply` to carry the delta into code.
+   - Everything done and implemented -> suggest `/opsx:archive`.
+
+**Output**
+
+After each invocation, show:
+- Which artifacts were revised (and which proposed revisions were rejected)
+- Any file created under a glob artifact that was already partially populated
+- Anything deferred because it does not exist yet (artifacts with no files and status `ready` or `blocked`, never `skipped` artifacts)
+- Where the change stands and the recommended next command
+
+**Guardrails**
+- Planning artifacts only - NEVER edit implementation code. If the revised plan implies code changes, stop and point to `/opsx:apply`.
+- Use the artifact ids and paths reported by `openspec status`; never branch on hardcoded artifact names.
+- Edit only the concrete files in `existingOutputPaths`; never write to a glob `resolvedOutputPath`.
+- Do not advance the build frontier: if an artifact has empty `existingOutputPaths` and status `ready` or `blocked`, creating them is a separate step, outside this workflow. Leave `skipped` artifacts untouched. The only new-file scope is a confirmed concrete path under a glob artifact whose `existingOutputPaths` is non-empty.
+- Confirm every edit with the user before writing.
+- If the request changes the change's *intent* rather than refining it, ask for a distinct unused change name and recommend `openspec new change "<new-change-name>"` instead (the "Update vs. Start Fresh" heuristic).

+# OpenVidu Dashboard
+
+Admin web application bundled with every OpenVidu deployment: live monitoring and usage analytics of rooms,
+participants, tracks, egress and ingress, read from the MongoDB analytics database written by the OpenVidu server
+(`openvidu-livekit`, `openvidu/analytics/`). This workspace is the Community edition (**CE**, `dashboard-ce/`); the
+commercial PRO edition extends its packages from a workspace of its own. `README.md` covers commands, the image,
+configuration variables and exit codes.
+
+## Working rules
+
+1. Code, comments, specs, README, CHANGELOG and commit messages are in English. Comments only for non-obvious
+   constraints; never narrate history or the conversation in code or docs.
+2. Before adding or upgrading a library, check its latest stable version on npm (`npm view <pkg> version`) and its
+   current API through Context7. Versions are pinned exactly; a dependency used by several packages goes once in the
+   `catalog` of `pnpm-workspace.yaml`; install scripts stay disabled except those listed in `allowBuilds`.
+3. When something is ambiguous, infeasible or unexpected, stop and ask the owner instead of deciding.
+4. Run `./dashboard.sh check` before reporting work as done. Suites that need Docker cannot run from a bare checkout:
+   say so instead of reporting a pass.
+5. Keep the `AGENTS.md` files current in the same change as the command, path or convention they describe. Each
+   `CLAUDE.md` is a symlink to the `AGENTS.md` beside it.
+
+## Spec-driven workflow (OpenSpec)
+
+- `openspec/specs/<capability>/spec.md` describe the current behaviour and are its source of truth; project context and
+  per-artifact rules live in `openspec/config.yaml`.
+- `/opsx:propose <name>` → owner review → `/opsx:apply` → `/opsx:archive`; no implementation without an approved
+  change. Decisions go to the change's `design.md`, project-wide ones also to the `context` of `openspec/config.yaml`.
+- Archiving syncs the delta specs into `openspec/specs` and deletes the change folder (no archive copy), in a commit
+  "openvidu-dashboard: archive <name>, keep only the specs". `./dashboard.sh spec-validate` must pass.
+- Start Claude Code sessions from this directory so the OpenSpec skills and `/opsx:*` commands load.
+
+## Layout
+
+| Path                                | Contents                                                                     | Agent notes |
+| ----------------------------------- | ---------------------------------------------------------------------------- | ----------- |
+| `dashboard-ce/typings`              | Contract shared by backend, frontend and the writer; API types               | `README.md` |
+| `dashboard-ce/backend`              | Express 5 REST API; serves the built SPA                                     | `AGENTS.md` |
+| `dashboard-ce/frontend`             | Thin CE application and, in `projects/dashboard-ui`, the library with all UI | `AGENTS.md` |
+| `dashboard-ce/e2e`                  | Playwright tests against the built applications                              | `AGENTS.md` |
+| `dashboard-ce/docker`               | Image and its smoke test                                                     | `AGENTS.md` |
+| `dashboard-ce/tools/data-generator` | Contract-valid analytics data for tests and the local demo                   | `README.md` |
+| `openspec/`                         | Specs and in-progress changes                                                |             |
+
+Build order: `typings` → `backend` → `dashboard-ui` → `frontend`. Workspace packages are consumed from their TypeScript
+sources through the `source` export condition, so type checking, linting and tests need no build; the runtime uses
+`dist`.
+
+## Commands
+
+Everything runs through `./dashboard.sh` (what CI calls; `help` lists every command, any accepts `--skip-install`):
+`check` (lint, format check, typecheck, spec validation, unit tests), `test-integration` (Docker), `e2e`,
+`contract-check <openvidu-livekit>`, `build-image ce`, `smoke-image ce`, `dev` (backend and frontend development
+servers against openvidu-local-deployment; README "Development") and `demo ce`: a local demo on generated data
+(http://localhost:4200, `admin` / `admin`; MongoDB container `openvidu-dashboard-demo-mongo` on port 27018;
+`DASHBOARD_DEMO_KEEP_DATA=true` reuses the data of a running container).
+
+Node 24 and pnpm through Corepack. Node stays on 24 until OpenVidu Meet moves to 26; TypeScript stays on 6 until the
+Angular toolchain supports 7. Prettier: tabs, width 120, single quotes, no trailing commas; ESLint fails on warnings.
+
+CI (`.github/workflows/openvidu-dashboard-ci.yml` of the `openvidu` repository, jobs `checks`, `unit`, `integration`,
+`contract`, `e2e`) runs every job on `ubuntu-latest`, with actions pinned to commit SHAs. The image is built and
+published by `docker-release.yaml` in openvidu-deployment.
+
+## Edition model
+
+- Backend: CE exports `startDashboard(options)`; an extending edition calls it with a `configure(container)` that
+  rebinds DI tokens and registers its routes over the CE locks, and with `startupHooks` that run before it listens.
+- UI: every CE page and building block lives in the `dashboard-ui` library; the applications only compose routes. An
+  extending edition adds its pages over locked CE routes and fills explicit seams (see the library README). Keep seams
+  open in CE (injectable services, route configs, content projection) and never put logic in the shells.
+- `GET /api/v1/info` reports the edition and its features. CE shows PRO features locked, never hidden; PRO API routes
+  answer `403 PRO_FEATURE` in CE.
+
+## Data contract
+
+- The contract lives in `dashboard-ce/typings` (see its README): sources in `contract/`, generated `schema/` and
+  `fixtures/` (never edited by hand), vendored by the writer, schema version checked by both sides at startup.
+- Adding or changing a field is one change covering the writer projector, typings, the legacy migration mapping, the
+  collection validator and tests on both sides; `./dashboard.sh contract-check` verifies it end to end.
+- No secrets in the analytics database. Participant counters count STANDARD sessions; the other kinds are services.
+

+
+## 3.10.0 (unreleased)
+
+### Upgrade notes
+
+- The first start after the upgrade migrates the existing analytics data in the background; the dashboard shows the
+  progress. Legacy `events` is renamed `legacy_events` and expires with its TTL; `active_entities` and `last_alive` are
+  removed.
+- `ADMIN_USERNAME` and `ADMIN_PASSWORD` are required: the dashboard no longer starts with built-in credentials.
+- `LOG_LEVEL` defaults to `info` instead of `debug`, and `SERVER_PORT` to `5000` (the port every installer sets)
+  instead of `3000`.
+- The image runs as uid 1000: mounted configuration and certificate authority files must be readable by that user.
+- Client IP addresses are no longer stored by default; set `openvidu.analytics.anonymize_ip: false` to store them.
+- The analytics data and the dashboard require MongoDB: on Amazon DocumentDB the server starts with analytics disabled
+  and logs why.
+
+### Breaking changes
+
+- The server no longer writes the legacy `stats`, `active_entities` and `last_alive` collections nor events in the
+  legacy document shape, and its Redis analytics sink is removed.
+- The API moves to `/api/v1`; the unversioned routes and `POST /api/login` are removed.
+
+### Deprecated
+
+- `openvidu.analytics.expiration`: mapped to `retention.events` and `retention.stats`, which replace it.
+- `openvidu.analytics.fixer_interval`: replaced by `openvidu.analytics.reconciler.interval`.
+
+### Added
+
+#### UI
+
+- Overview page with live counters of rooms, participants, publishers, egress, ingress and agents linked to their
+  lists, today's figures, recent rooms, the data pipeline health (writer and nodes reporting) and stale-data notices.
+- Participants page with live refresh: active participants, sessions in range and active services; search participant
+  sessions by identity or SID, filter by kind (standard participants by default), status, room and publishers, sort by
+  join, leave and duration, and see the sources each session published.
+- Agents page listing agent sessions with a live counter and the agent sessions of the range, searchable by identity
+  and sortable by join, leave and duration.
+- One time range for every page, with presets, custom ranges and any time zone; the range picker warns while the start
+  of the range predates the retention of the page's data.
+- Every list, chart and detail view is reproducible from its URL; Back restores filters, sort and page, and the time
+  zone picked in the range picker or the header zone chip applies to every page of the session.
+- Global search, and one search box with hints on every list: an exact ID shows its entity whatever the range and
+  filters, and Enter opens it. Empty lists offer Clear filters and Widen range, and an unknown ID says so.
+- Server status banners on every page: no analytics data received, schema and migration progress; they follow the
+  server even with auto-refresh off, and the connectivity and no-data banners appear only after two bad results in a
+  row.
+- A LIVE label that reads paused while auto-refresh is off and stale when data stops arriving, judged with the writer's
+  batch interval.
+- Info icons next to tiles, cards, charts and columns explain the terms they show, such as participant sessions and
+  unique identities; they open on hover, keyboard focus or a tap.
+- Settings page with viewer preferences (any time zone as the default) and an About tab with the OpenVidu version, the
+  migration progress while it runs, the retention per data class and the storage.
+- PRO features appear locked in CE with a short explanation and a link.
+
+#### Data
+
+- New analytics data model: one document per room session, participant session, published track, subscription,
+  egress, ingress and ingress session, plus raw events, statistics time series and 5-minute, hourly and daily rollups
+  (API calls by method, ingress sessions by input type), with a schema version that the server and the dashboard check
+  at startup.
+- The server writes the analytics model in idempotent per-node batches, with a retention per data class.
+- `openvidu.analytics` options `retention` (per data class, in days: `events`, `stats`, `tracks` and `rollups_5min`
+  7 days, `entities` 90 days, `rollups_hourly` 400 days and `rollups_daily`, unlimited unless set), `stats_detail`,
+  `anonymize_ip`, `store_metadata`, `events.store_types`, `queue` and `validation_action`.
+- Legacy analytics data is migrated to the new model automatically.
+- Versioned API under `/api/v1`: rooms, participants and agents, egress and ingress lists with their summaries, sorted
+  by metrics (durations, end times, counters) within a range limit reported by `GET /api/v1/info`; an exact ID always
+  finds its entity whatever the range and filters, and active rooms and participants carry a `stale` flag.
+- Analytics API: `/api/v1/analytics/series`, `/breakdowns`, `/summary` and `/export.csv`, read from the rollup
+  collections.
+- Overview API: `GET /api/v1/overview` with live counters, today's totals and recent rooms.
+- Status API: `GET /api/v1/status` with the schema status, migration progress, writer health and the writer's batch
+  interval, from which the writer, node and stale-data windows widen for slow batches.
+- API reference outside production: an OpenAPI 3.1 document at `/api/v1/docs/openapi.json` and a browsable page at
+  `/api/v1/docs`, with operation IDs, described parameters and every error response.
+
+#### Deployment
+
+- The CE dashboard is open source, in `openvidu-dashboard/` of the OpenVidu repository, with its image build and tests.
+- `openvidu.analytics.migration.*` settings control the migration.
+- Analytics durations accept days (`7d`, `1d12h`), and the server refuses to start on a retention above the MongoDB TTL
+  limit, an entity retention under 2 days or a daily rollup retention shorter than the hourly one, naming the key.
+- The server logs a warning when a full analytics queue drops entries, at most once per queue and batch interval.
+- `DATABASE_TLS_CA_FILE` trusts a private certificate authority for external MongoDB services.
+- The dashboard refuses to start (exit code 3) against an OpenVidu server whose analytics schema is older than it
+  supports, and reports a newer or uninitialized schema in `GET /api/v1/info`.
+- The image declares a Docker `HEALTHCHECK`, through the `healthcheck` argument of the backend entry.
+- `GET /api/v1/health` and `GET /api/v1/ready` probes.
+- Login is rate limited per IP (10 failed attempts per 15 minutes).
+- Settings `DASHBOARD_JWT_SECRET`, `DASHBOARD_REFRESH_TOKEN_TTL`, `DASHBOARD_COOKIE_SECURE`, `DASHBOARD_TRUST_PROXY`,

+
+### Improved
+
+#### UI
+
+- Sign-in sessions survive page reloads and expire after 7 days without use, with no credential or access token
+  stored in the browser.
+- The shell works at every screen size, with the OpenVidu version, the edition badge and documentation links at the
+  bottom of the sidenav.
+- The Rooms list covers any range instead of the active rooms and those closed in the last 28 days, with status, name
+  or SID and feature filters, sorts by start, end, duration, unique identities and active participants, summary tiles
+  and live refresh.
+- Egress and ingress get a list each instead of one shared page. Egress: searchable by room name or egress ID, with
+  type, status and room filters and sorts by start, end and duration. Ingress: the ingresses created, used or
+  publishing in the range, searchable by name or ID, with input type and status filters and sorts by creation, total
+  duration, sessions and last session. Both with summary tiles and live refresh.
+- Analytics covers any range instead of four fixed periods, loads on demand and exports CSV, with rooms, participants,
+  client, data transferred, egress and ingress (with the input type) sections; every series of a chart has its own
+  colour, and a section without data shrinks to its "No data in this range" message.
+- Auto-refresh offers one interval for every live view; a page that cannot refresh now, such as an ended room, shows
+  why on the disabled interval control.
+- Tables show every selected column and scroll sideways when they do not fit, turn into cards only on phones, keep
+  their rows while they refresh and show skeletons only before their first data.
+- Enum values read as friendly labels, durations count up live and charts update in place; every time-series chart
+  names its bucket and time zone.
+- Light and dark themes meet WCAG AA, with self-hosted fonts and icons.
+
+#### Data
+
+- Participant counts, sessions, minutes, unique identities and client breakdowns count standard participants only;
+  egress, ingress, agent and SIP sessions are counted apart, by kind.
+- Participants, tracks and subscriptions left by a crashed or stopped server node are closed within 2 minutes, and
+  their rooms with the last of their sessions once LiveKit's dead node cleanup released them, with an end time accurate
+  to 30 s (`openvidu.analytics.reconciler` options `enabled`, `interval` and `max_closures_per_run`); a recording lost
+  with its node is reported as failed.
+- Analytics events and statistics queued in a node are written before it stops on a graceful shutdown.
+- Credentials are never stored in the analytics database; metadata is stored only with `store_metadata`, and client
+  IP addresses are left out unless `anonymize_ip: false`.

+# OpenVidu Dashboard
+
+Web application bundled with every OpenVidu deployment that gives administrators live monitoring and usage
+analytics of rooms, participants, tracks, egress and ingress. It reads the MongoDB analytics database written
+by the OpenVidu server (`openvidu-livekit`).
+
+This workspace holds the Community edition (CE, `dashboard-ce/`). OpenVidu PRO deployments run a commercial edition
+built on these packages, whose features CE shows locked.
+

+
+## Requirements
+
+- Node.js 24 (see `.node-version`)
+- pnpm, enabled through Corepack (`corepack enable`); the version is pinned by `packageManager` in
+  `package.json`
+
+## Browser support
+
+Current Chrome, Edge, Firefox and Safari: the theme needs CSS `light-dark()` (Chrome and Edge 123, Firefox 120,
+Safari 17.5).
+
+## Commands
+
+All tasks run through `./dashboard.sh`:
+
+```bash
+./dashboard.sh install            # install dependencies
+./dashboard.sh check              # lint + format check + type check + spec validation + unit tests
+./dashboard.sh dev                # backend and frontend dev servers against openvidu-local-deployment
+./dashboard.sh demo ce            # local demo on generated data: http://localhost:4200, admin / admin
+./dashboard.sh test-integration   # integration tests against MongoDB (Docker required)
+./dashboard.sh e2e                # build the application and run the Playwright tests
+./dashboard.sh build-image ce     # build openvidu/openvidu-dashboard:dev
+./dashboard.sh smoke-image ce     # smoke test and size budget of that image
+./dashboard.sh contract-check ../openvidu-livekit   # data model contract check against the writer
+./dashboard.sh help               # list every command
+```
+
+## Development
+
+`./dashboard.sh dev` runs the backend and frontend development servers against the MongoDB of an
+[openvidu-local-deployment](https://github.com/OpenVidu/openvidu-local-deployment) running on this machine, both
+reloading on changes: http://localhost:4200, `admin` / `admin`. Ctrl+C stops both. Without a deployment,
+`./dashboard.sh demo ce` runs the same servers on generated data instead.
+
+- Before starting, it checks the configuration and that MongoDB answers, and says what to do when it does not.
+- The backend reads `dashboard-ce/backend/dev.env`, the defaults for the local deployment. A git-ignored
+  `dashboard-ce/backend/.env` overrides them, and the environment overrides both, for example
+  `DATABASE_URL` for another MongoDB or `LOG_LEVEL=debug`. The deployment's replica set advertises its member
+  as `mongo:27017`, which only Docker resolves, so a URL from the host needs `directConnection=true`.
+- `DASHBOARD_DEV_PORT` (default 4200) and `DASHBOARD_DEV_BACKEND_PORT` (default 5000) move the servers, for
+  example off port 5000 where macOS runs AirPlay.
+- The deployment needs a 3.10 OpenVidu server: data appears once it writes the analytics database, and an
+  older writer schema stops the check.
+
+## Container image
+
+`openvidu/openvidu-dashboard`, built from `dashboard-ce/docker/Dockerfile` on `node:24-trixie-slim`
+(`node dist/server.js`).
+
+- The build context is this directory. `IMAGE_TAG` (default `dev`) and `BASE_HREF` (default `/`; deployments use
+  `/dashboard/`) apply.
+- The image runs as uid 1000 and writes nothing to disk; mounted files (`DASHBOARD_CONFIG_PATH`,
+  `DATABASE_TLS_CA_FILE`) must be readable by that user. The container listens on `SERVER_PORT` (5000) and its
+  `HEALTHCHECK` requests `GET /api/healthcheck` on that port.
+- `./dashboard.sh smoke-image ce` checks `MONGO_ENABLED=false`, health, `GET /api/healthcheck`, `HEAD /`, uid 1000,
+  `SERVER_PORT`, `docker stop` and the 300 MB size budget.
+
+## Configuration
+
+Environment variables, optionally loaded from the file at `DASHBOARD_CONFIG_PATH` (the environment wins). New names
+start with `DASHBOARD_`, or `DATABASE_` for database connection settings; the others keep their 3.9 meaning.

+# Backend (`@openvidu-dashboard/backend`)
+
+Express 5, Inversify, Zod and the official `mongodb` driver; TypeScript 6 strict ESM, relative imports end in `.js`.
+Behaviour is specified in `openspec/specs/*-api`, `api-conventions`, `auth`, `status-api` and `editions-info`.
+
+## Structure
+
+- `src/lifecycle/startup.ts`: `startDashboard(options)` reads the configuration, connects to MongoDB, applies the
+  writer schema gate, builds the container, calls `configure` and the startup hooks, then listens. Exit codes go
+  through `Shutdown.run(code)`.
+- `src/di/container.ts`: `buildContainer()` binds the CE services and extension tokens and registers the CE routes.
+  `TOKENS` (`src/di/tokens.ts`) are bound with `toResolvedValue` factories, without decorators, so esbuild and Vitest
+  need no metadata.
+- Routes are declared once in the `RouteRegistry` (`src/api/route-registry.ts`): method, path under `/api/v1`, edition,
+  `feature` of a PRO route, a unique `operationId` (camelCase, verb first: `listRooms`, `getRoomsSummary`), tags
+  declared first with `registry.tag(name, description)`, security (`public`, `bearer`, `optional-bearer`, plus
+  `refreshCookie` for the auth routes), Zod schemas of params, query, body and responses, and the handler. It drives
+  validation, authentication and the OpenAPI document (`src/api/openapi.ts`, only when `NODE_ENV` is not `production`).
+- OpenAPI rules, enforced by `test/integration/openapi-document.test.ts` through `documentationIssues()`
+  (`test/support/openapi-checks.ts`): every parameter has a description (`.meta({ description })`; the generator lifts
+  one set before `.default()` or `.optional()`), comma-separated lists use `csvParam()` or an array `override`, errors
+  without a schema get `ApiError`, `400` and `401` are added from the input and the security, and a response only one
+  edition answers carries `edition`.
+- PRO routes are only locks here: `registry.lock({ method, path, feature })` answers `403 PRO_FEATURE` after
+  authentication and stays out of the OpenAPI document. An edition that extends CE registers the full definition in the
+  lock's place (mount order kept) and swaps a CE route for its extension with `registry.replace()`; a `pro` startup
+  that leaves a lock without a definition exits with code 1, naming it.
+- Extension tokens that `configure` can rebind: `Features`, `AnalyticsCatalogue` (metrics and dimensions the
+  analytics endpoints compute) and `OverviewExtension` (extra overview fields, merged before the `ETag`). A
+  `configure` that throws stops the startup with code 1.
+- A resource slice is `src/<resource>/`: `*-schemas.ts` (Zod), `*-query.ts` (pure filter builders), `*-repository.ts`
+  (MongoDB), `*-service.ts` (paging, mapping), `*-responses.ts` (OpenAPI response schemas, checked against the mappers
+  in unit tests) and `*-routes.ts` (`register<Resource>Routes`: the CE routes and the locks of the PRO ones).
+- Zod schemas live here because typings has no runtime dependencies; typings declares the matching types in
+  `src/api/`. Errors use `{ error: { code, message, details? } }` with `ErrorCode`.
+- Shared query pieces in `src/api/`: `rangedQuery(now, shape)` for ranged queries (relative grammar resolved at parse
+  time) and `optionalRangeQuery(now, shape)` when the bounds are optional, `pageQuery()` for keyset pages on an index
+  ending in `_id`, `indexOrderedPage()` when the index does not order by `_id`, and `rankedPage()` with
+  `assertRankedRange()` (`src/api/ranked.ts`) for metric sorts ranked in memory at the cursor's `asOf`. Calendar math in
+  a time zone uses date-fns and `@date-fns/tz`.
+- `src/stats/stats-mode.ts`: `StatsModeReader` reads the writer's `stats_detail` for `GET /info`.
+- `src/analytics/` answers from the rollup collections only: `analytics-planner.ts` picks the granularity, source
+  collection and bucket grid, `analytics-counters.ts` folds the documents in process with the definitions of the
+  catalogue, `AnalyticsCache` keeps the folds of completed documents and `AnalyticsFeatureGate` rejects PRO metrics,
+  dimensions and node scopes on CE.
+- `src/status/freshness.ts` marks active rooms and participants `stale` with the backend clock, from the typings
+  `freshnessWindows()`.
+- `src/index.ts` exports what an extending backend builds on: the startup, tokens and registry, the generic query,
+  cursor, response and freshness pieces, and the list pieces that entity details extend.
+- Exact identifiers (`RM_`, `PA_`, `EG_`, `IN_`, `TR_`) are matched with `ENTITY_ID_PATTERNS`, `isEntityId()` and
+  `entityIdKind()` from typings.
+- Configuration variables are new `DASHBOARD_*`, or `DATABASE_*` for database connection settings; legacy names keep
+  their 3.9 meaning (`src/config/variables.ts`, unit-tested). The README lists them all.
+- `scripts/dev.ts` (exported as `@openvidu-dashboard/backend/dev`) serves `./dashboard.sh dev`: `loadDevEnv()` (the
+  environment, then `.env`, then `dev.env`; `scripts/dev-preload.ts` for `tsx watch --import`) and
+  `checkDevConfig()` (`scripts/dev-check.ts`). `dev.env` holds the openvidu-local-deployment defaults; never give
+  `src/` defaults for required variables, since a deployment must fail when they are missing.
+
+## Rules
+
+- Repositories own the queries. Every list, detail and time-series query is backed by an index and asserted with
+  `expectIndexBacked` (`test/support/query-plan.ts`: no COLLSCAN above 1 000 documents, bounded `totalDocsExamined`).
+
+## Tests
+
+- Unit tests: Vitest (`pnpm test`).
+- Integration tests: `test/integration/`, Vitest projects `integration` and `integration-plans` (the `*query-plan`
+  suites, run after the rest so their data generation does not skew the latency budgets). `test/support/` starts a
+  replica set with Testcontainers on `openvidu/mongodb:8.0.29-r1` (the official `mongo:8.0` refuses Linux kernels 6.19
+  and newer), or uses `DASHBOARD_TEST_MONGO_URI`; `DASHBOARD_TEST_MONGO_IMAGE` overrides the image. Through pnpm
+  without Docker the suites report themselves skipped; `./dashboard.sh test-integration` fails instead.
+- They also need `openssl` (test CA of the TLS case) and build the package to run `dist/server.js` as a process.
+  `test/support/boot.ts` starts the dashboard in-process on a fresh database with a controllable clock.
+- `test/support/` is exported to the suites of extending packages as `@openvidu-dashboard/backend/testing` (source
+  only, never in `dist`), and the MongoDB global setup as `@openvidu-dashboard/backend/testing/global-mongo`.
+- Query-plan suites generate data with `dashboard-ce/tools/data-generator` and report the p95 of their budget. Design
+  figures come from scenario M over 7 days on a MongoDB with room for it, run alone:
+
+  ```bash
+  DASHBOARD_TEST_MONGO_URI=<uri> ROOMS_PLAN_SCENARIO=M ROOMS_PLAN_DAYS=7 ROOMS_PLAN_REPORT=<file> \
+    pnpm --filter @openvidu-dashboard/backend exec vitest run --project integration-plans \
+    test/integration/rooms-query-plan.test.ts
+  ```

+\`Authorization: Bearer <token>\`, and sets the \`${REFRESH_COOKIE}\` cookie, scoped to the auth endpoints;
+\`POST /api/v1/auth/refresh\` exchanges that cookie for a new access token.
+
+**Time ranges.** \`from\` and \`to\` take an ISO 8601 instant with an offset or a relative expression (\`now\`,
+\`now-<n>m|h|d\`, \`now/d\`, \`now/M\`), resolved in the IANA time zone \`tz\` (default \`UTC\`).
+
+**Pagination.** Lists return \`items\`, the opaque cursors \`nextCursor\` and \`prevCursor\`, and \`total\`. Pass a
+cursor back unchanged with the same filters; \`limit\` sets the page size.
+
+**Errors.** Every error answers \`{ error: { code, message, details? } }\` (\`ApiError\`); a \`400\` lists the invalid
+parameters in \`details.issues\`.
+
+**Conditional requests.** A response with an \`ETag\` answers \`304\` to a matching \`If-None-Match\`.
+
+**Request IDs.** Every response carries \`X-Request-Id\`: the one the request sent, or a generated one.
+
+**Versioning.** Additive changes (new endpoints, optional parameters, response fields and enum values) stay in \`v1\`;
+clients ignore unknown fields and enum values.`;
