Subject: [PATCH] feat: initial OpenSpec skills + /opsx commands for ZCode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Port of @fission-ai/openspec@1.4.1 workflow templates into ZCode-native
skills and slash commands.

- 11 skills (skills/openspec-*/SKILL.md): auto-trigger + /skill force-load
- 11 commands (commands/opsx/*.md): /opsx:explore, /opsx:propose, /opsx:apply,
  /opsx:sync, /opsx:archive, /opsx:new, /opsx:continue, /opsx:ff, /opsx:verify,
  /opsx:bulk-archive, /opsx:onboard
- install.sh / install.ps1 (idempotent, copies to ~/.zcode/)
- uninstall.sh / uninstall.ps1
- README.md with command table, install/update/uninstall, upstream mapping

Skill instruction text is ported verbatim from the upstream
get…SkillTemplate().instructions fields, with three ZCode adaptations:
1. /opsx:<cmd> cross-refs inside skill bodies → /skill openspec-<name>
2. Task tool → Agent tool (one occurrence in openspec-archive-change)
3. Source-version comment header in each SKILL.md

+# openspec-zcode
+
+[OpenSpec](https://github.com/Fission-AI/openspec) spec-driven development (SDD) skills and `/opsx:*` slash commands for the **ZCode** harness.
+
+This repo ports the 11 OpenSpec workflow commands (the `/opsx:*` family) into ZCode-native **skills** (auto-triggering instructions) plus matching **slash commands** (so you can type `/opsx:propose` in chat, exactly like in Claude Code or Cursor).
+
+The skills are thin steering wrappers around the **OpenSpec CLI** (`@fission-ai/openspec`), which remains the engine for artifact-dependency resolution, schema handling, and path resolution. You need the CLI installed and a project initialized with `openspec init`.
+
+## What you get
+
+- **11 skills** (`openspec-*`) — full workflow instructions, auto-triggered by intent or force-loaded via `/skill openspec-<name>`.
+- **11 slash commands** (`/opsx:*`) — thin wrappers that mount the matching skill and pass `$ARGUMENTS` through.
+
+| `/opsx` command | Skill | Purpose |
+|---|---|---|
+| `/opsx:explore` | `openspec-explore` | Thinking partner — investigate, brainstorm, clarify. No implementation. |
+| `/opsx:propose` | `openspec-propose` | Create a change + generate all artifacts (proposal/specs/design/tasks) in one step. |
+| `/opsx:apply` | `openspec-apply-change` | Work through `tasks.md`, writing code and checking off items. |
+| `/opsx:sync` | `openspec-sync-specs` | Merge a change's delta specs into main specs without archiving. |
+| `/opsx:archive` | `openspec-archive-change` | Finalize a change: completion check, optional sync, move to archive. |
+| `/opsx:new` | `openspec-new-change` | Scaffold a new change folder and show the first artifact template, then stop. |
+| `/opsx:continue` | `openspec-continue-change` | Create the next single ready artifact. |
+| `/opsx:ff` | `openspec-ff-change` | Fast-forward: create all planning artifacts in dependency order at once. |
+| `/opsx:verify` | `openspec-verify-change` | Validate implementation (Completeness/Correctness/Coherence). |
+| `/opsx:bulk-archive` | `openspec-bulk-archive-change` | Archive multiple changes at once with cross-change conflict resolution. |
+| `/opsx:onboard` | `openspec-onboard` | Guided end-to-end tutorial on a real task in your codebase. |
+
+## Prerequisites
+
+1. **Node.js 18+** and npm.
+2. **OpenSpec CLI**, installed globally:
+   ```bash
+   npm install -g @fission-ai/openspec
+   openspec --version   # should print e.g. 1.4.1
+   ```
+3. **A project initialized with OpenSpec** (run once per repo):
+   ```bash
+   cd /path/to/your/project
+   openspec init
+   ```
+   This creates `openspec/config.yaml`, `openspec/specs/`, and `openspec/changes/`.
+4. **ZCode** (this harness).
+
+## Install
+
+### Linux / macOS / Git Bash on Windows
+
+```bash
+git clone https://gts.meratalk.online/keboss/openspec-zcode.git
+cd openspec-zcode
+./install.sh
+```
+
+### Native Windows (PowerShell)
+
+```powershell
+git clone https://gts.meratalk.online/keboss/openspec-zcode.git
+cd openspec-zcode
+.\install.ps1
+```
+
+Both scripts copy:
+- `skills/openspec-*` → `~/.zcode/skills/openspec-*/`
+- `commands/opsx/*.md` → `~/.zcode/commands/opsx/*.md`
+
+Override the target directory with `ZCODE_HOME`:
+
+```bash
+ZCODE_HOME=/custom/path ./install.sh
+# PowerShell: $env:ZCODE_HOME = "C:\custom\path"; .\install.ps1
+```
+
+**Restart ZCode** (or start a new session) after installing so it re-scans the skills and commands directories.
+
+## Update
+
+```bash
+cd openspec-zcode
+git pull
+./install.sh      # or .\install.ps1
+```
+
+The install scripts are idempotent — re-running overwrites existing copies cleanly.
+
+## Uninstall
+
+```bash
+./uninstall.sh     # or .\uninstall.ps1
+```
+
+Removes `~/.zcode/skills/openspec-*/` and `~/.zcode/commands/opsx/*.md`. Leaves the rest of your ZCode config untouched.
+
+## Usage
+
+Open ZCode in any project with `openspec/` initialized. Two ways to invoke:
+
+**Slash commands** (explicit, like the upstream OpenSpec UX):
+```
+/opsx:propose add-realtime-presence
+/opsx:apply add-realtime-presence
+/opsx:archive add-realtime-presence
+```
+
+**Skills** (auto-trigger by intent, or force-load):
+```
+/skill openspec-propose
+"Let's think through the auth redesign"   → auto-triggers openspec-explore
+```
+
+## Layout
+
+```
+openspec-zcode/
+├── skills/
+│   └── openspec-{explore,propose,apply-change,sync-specs,archive-change,
+│                  new-change,continue-change,ff-change,verify-change,

+
+## How it maps to upstream OpenSpec
+
+Upstream OpenSpec (`@fission-ai/openspec`) ships per-AI-tool installers that generate two artifacts per command: a skill file and a command file. The table of supported tools (Claude Code, Cursor, Codex, Windsurf, …) lives in the upstream `docs/supported-tools.md`. This repo adds the **ZCode** entry to that matrix:
+
+| Artifact | ZCode path |
+|---|---|
+| Skills | `~/.zcode/skills/openspec-<name>/SKILL.md` |
+| Commands | `~/.zcode/commands/opsx/<name>.md` → `/opsx:<name>` |
+
+The skill bodies are ported verbatim from `@fission-ai/openspec@1.4.1` (`dist/core/templates/workflows/*.js`, the `instructions` field of each `get…SkillTemplate()`), with three minimal adaptations for the ZCode harness:
+
+1. Cross-references inside skill bodies: `/opsx:<cmd>` → `/skill openspec-<name>` (the slash commands themselves keep `/opsx:*`).
+2. `Task tool (subagent_type: "general-purpose")` → `Agent tool (subagent_type: "general-purpose")` (one occurrence, in `openspec-archive-change`).
+3. A source-comment header in each `SKILL.md` recording the upstream version for future re-syncs.
+
+Everything else — all `openspec … --json` CLI calls, all `AskUserQuestion tool` / `TodoWrite tool` references (both exist natively in ZCode), all artifact dependency logic — is unchanged, because the OpenSpec CLI remains the engine.
+
+## Re-syncing after an OpenSpec upgrade
+
+When `@fission-ai/openspec` releases a new version and you want the latest skill instructions:
+
+1. `npm install -g @fission-ai/openspec@latest`
+2. Re-extract the `instructions` field of each `get…SkillTemplate()` from the new `dist/core/templates/workflows/*.js`.
+3. Re-apply the three adaptations above.
+4. Bump the version comment in each `SKILL.md` header.
+5. `./install.sh` to redeploy.
+
+The skill names and command names are stable across versions; only the instruction text changes.
+
+## License
+
+The skill instruction text is ported from `@fission-ai/openspec` (MIT licensed). Everything else in this repo is provided under MIT as well.

+
+Implement tasks from an OpenSpec change.
+
+**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 use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/skill openspec-apply-change <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
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+   **Workspace guard:** If status JSON reports `actionContext.mode: "workspace-planning"` and `allowedEditRoots` is empty, explain that full workspace apply is not supported in this slice. Treat linked repos and folders as read-only context, ask the user to select an affected area through an explicit implementation workflow, and STOP before editing files.
+
+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
+
+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
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - 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: suggest archive
+   - 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**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**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
+- Use contextFiles from CLI output, don't assume specific file names
+
+**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.
+
+**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. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+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` or other)
+
+   If status reports `actionContext.mode: "workspace-planning"`, explain that workspace archive is not supported in this slice and STOP. Do not move workspace changes into repo-local archives or edit linked repos.
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Agent tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **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/YYYY-MM-DD-<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**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- 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, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Archive multiple completed changes at once. Use when archiving several parallel changes, batch-archive multiple OpenSpec changes, or finalize several completed changes together with cross-change spec conflict resolution.
+---
+
+<!-- Source: @fission-ai/openspec@1.4.1, dist/core/templates/workflows/bulk-archive-change.js
+     Ported for ZCode harness. Requires openspec CLI (npm i -g @fission-ai/openspec).
+     Slash command: /opsx:bulk-archive   Force-load: /skill openspec-bulk-archive-change -->
+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName`, `artifacts`, `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`
+      - Note which artifacts are `done` vs other states
+
+      If any selected change reports `actionContext.mode: "workspace-planning"`, explain that workspace bulk archive is not supported in this slice and STOP before syncing specs or moving changes. Do not fall back to repo-local paths or edit linked repos.
+
+   b. **Task completion** - Read `artifactPaths.tasks.existingOutputPaths` from status JSON
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `artifactPaths.specs.existingOutputPaths` from status JSON
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change              | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
+   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
+   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
+   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:
+      ```bash
+      mkdir -p "<planningHome.changesDir>/archive"
+      mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+      ```
+
+   c. **Track outcome** for each change:
+      - Success: archived successfully
+      - Failed: error during archive (record error)
+      - Skipped: user chose not to archive (if applicable)
+
+9. **Display summary**
+
+   Show final results:
+
+   ```
+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
+   - project-config -> archive/2026-01-19-project-config/
+   - add-oauth -> archive/2026-01-19-add-oauth/
+
+   Skipped 1 change:
+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Create a new change to get started.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+Continue working on a change by creating the next artifact.
+
+**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. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - 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 continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```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", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change or archive it."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `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
+     - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the `resolvedOutputPath` specified in instructions. If it is a glob pattern, choose the concrete file path using the schema instruction and workspace planning context
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file

+name: openspec-explore
+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change, brainstorm approaches, investigate the codebase, compare options, or sharpen a fuzzy idea before committing to a direction.
+---
+
+<!-- Source: @fission-ai/openspec@1.4.1, dist/core/templates/workflows/explore.js
+     Ported for ZCode harness. Requires openspec CLI (npm i -g @fission-ai/openspec).
+     Slash command: /opsx:explore   Force-load: /skill openspec-explore -->
+
+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, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**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.
+
+---
+
+## 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
+
+---
+
+## 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, schemas, and status
+- What the user might be working on
+
+### 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
+
+### 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**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/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)
+
+---

+
+     Want to update the design to reflect this?
+     Or add a spike task to investigate?
+```
+
+**User wants to compare options:**
+```
+User: Should we use Postgres or SQLite?
+

+```
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **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):
+- Create a change proposal
+- 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. Creating OpenSpec artifacts is fine, writing application code is not.
+- **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
+- **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

+
+Fast-forward through artifact creation - generate everything needed to start implementation in one go.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "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.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI.
+
+3. **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 with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** 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
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **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
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/skill openspec-apply-change` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- 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**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, suggest continuing that change instead
+- Verify each artifact file exists after writing before proceeding to next

+
+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "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.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change in the planning home resolved by the CLI.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Use the returned `planningHome`, `changeRoot`, `artifactPaths`, and `nextSteps` instead of assuming repo-local paths.
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema (e.g., `proposal` for spec-driven).
+   Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest continuing that change instead
+- Pass --schema if using a non-default workflow

+
+Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
+
+---
+
+## Preflight
+
+Before starting, check if the OpenSpec CLI is installed:
+
+```bash
+# Unix/macOS
+openspec --version 2>&1 || echo "CLI_NOT_INSTALLED"
+# Windows (PowerShell)
+# if (Get-Command openspec -ErrorAction SilentlyContinue) { openspec --version } else { echo "CLI_NOT_INSTALLED" }
+```
+
+**If CLI not installed:**
+> OpenSpec CLI is not installed. Install it first (`npm i -g @fission-ai/openspec`), then come back to `/skill openspec-onboard`.
+
+Stop here if not installed.
+
+---
+
+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+# Unix/macOS
+git log --oneline -10 2>/dev/null || echo "No git history"
+# Windows (PowerShell)
+# git log --oneline -10 2>$null; if ($LASTEXITCODE -ne 0) { echo "No git history" }
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/skill openspec-explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives at the `changeRoot` reported by `openspec status --change "<name>" --json` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: <changeRoot from status JSON>
+
+The folder structure:
+```
+<changeRoot>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to the `resolvedOutputPath` from `openspec instructions proposal --change "<name>" --json`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Resolve where the spec file should be created:
+```bash
+openspec instructions specs --change "<name>" --json
+# Use resolvedOutputPath from the JSON. If it is a glob, choose the concrete file path using the schema instruction and workspace planning context.
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to the concrete file path chosen from `resolvedOutputPath`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to the `resolvedOutputPath` from `openspec instructions design --change "<name>" --json`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to the `resolvedOutputPath` from `openspec instructions tasks --change "<name>" --json`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. The archive path is derived from `planningHome.changesDir` and the date.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `<planningHome.changesDir>/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.

+## Graceful Exit Handling
+
+### User wants to stop mid-way
+
+If the user says they need to stop, want to pause, or seem disengaged:
+
+```
+No problem! Your change is saved at the `changeRoot` reported by `openspec status --change "<name>" --json`.
+
+To pick up where we left off later:
+- `/skill openspec-continue-change <name>` - Resume artifact creation
+- `/skill openspec-apply-change <name>` - Jump to implementation (if tasks exist)
+
+The work won't be lost. Come back whenever you're ready.

+
+- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
+- **Keep narration light** during implementation—teach without lecturing
+- **Don't skip phases** even if the change is small—the goal is teaching the workflow
+- **Pause for acknowledgment** at marked points, but don't over-pause
+- **Handle exits gracefully**—never pressure the user to continue
+- **Use real codebase tasks**—don't simulate or use fake examples
+- **Adjust scope gently**—guide toward smaller tasks but respect user choice

+
+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run `/skill openspec-apply-change`
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "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.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **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 with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** 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
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **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
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/skill openspec-apply-change` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- 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**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- 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. Use when the user wants to update main specs with changes from a delta spec, without archiving the change, merge a change's delta specs into the source-of-truth specs, or apply ADDED/MODIFIED/REMOVED/RENAMED requirement deltas.
+---
+
+<!-- Source: @fission-ai/openspec@1.4.1, dist/core/templates/workflows/sync-specs.js
+     Ported for ZCode harness. Requires openspec CLI (npm i -g @fission-ai/openspec).
+     Slash command: /opsx:sync   Force-load: /skill openspec-sync-specs -->
+
+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).
+
+**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. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+   If status reports `actionContext.mode: "workspace-planning"`, explain that workspace spec sync is not supported in this slice and STOP. Do not fall back to repo-local paths or edit linked repos.
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   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**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   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 (don't need to copy existing ones)
+        - 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
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## 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
+#### 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`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## 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
+- 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

+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - Which artifacts exist for this change
+
+   If status reports `actionContext.mode: "workspace-planning"`, explain that full workspace implementation verification is not supported in this slice and STOP. Do not infer repo-local implementation ownership or edit linked repos.
+
+3. **Get planning context and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and `contextFiles` (artifact ID -> array of concrete file paths). Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If `contextFiles.tasks` exists, read every file path in it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `contextFiles.specs`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If `contextFiles.design` exists:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"
