Commit files related to a specific Spectra change.

This is a utility skill (not a workflow step). It reads source file tracking data and artifact changes to stage and commit only the files belonging to one change — useful when multiple changes are in progress simultaneously.

Input: Optionally specify a change name after /spectra-commit (e.g., /spectra-commit add-auth). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.

Prerequisites: This skill requires git. Run git --version. If git is not available (command not found or similar error), inform the user to install git and STOP.

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 spectra list --json to get available changes. Use the request_user_input 工具 to let the user select

   Always announce: "Committing for change: "

2. Read tracking file

   Check for .spectra/touched/<change-name>.json. If it exists, parse it to get source files grouped by task.

   Expected format:

   {
     "change": "<change-name>",
     "touched": [
       {
         "task_id": "1",
         "task_desc": "Task description",
         "files": ["src/file1.ts", "src/file2.ts"]
       }
     ]
   }
   

   If the file does not exist, proceed without source file data — only artifact files will be included.

3. Collect artifact files

   Run git status --porcelain and filter the output to files under openspec/changes/<name>/. These are the change's artifact files (proposal, design, tasks, specs, etc.).

4. Identify unrelated dirty files

   From the full git status --porcelain output, any dirty files NOT in the artifact set and NOT in the tracking file are "unrelated changes."

4a. [Clade fork] Claim-aware partition of unrelated changes

When multiple AI sessions work in parallel, some "unrelated changes" may
belong to **another active session's** worktree (not your current
commit's scope). Auto-committing them would silently swallow another
session's WIP. This step adds session-ownership classification.

Detection:
- Check whether `scripts/claim-helper.mjs` exists in the repo root.
- If yes, run `node scripts/claim-helper.mjs list` to enumerate active
  session claims on this consumer.
- If no claim infra is present, skip 4a entirely — fall through to
  upstream behavior (step 5).

For each path in "unrelated changes", classify by matching against each
active claim's `expected_paths` (glob support: exact match, `prefix/**`
recursive, `prefix/*` single-level):
- **Other-session paths**: matched to any active claim. **DO NOT** include
  in commit set under any user option, even "Include all dirty files",
  without explicit re-confirmation. List the matched session_id + change_id
  so the user knows which session owns the path.
- **Truly unrelated**: no claim match. Same upstream behavior — exclude by
  default, includable via "Include all dirty files".

5. Display commit plan

   Show the file list grouped into sections:

   ## Commit Plan: <change-name>
   
   ### Change Artifacts
   - M  openspec/changes/<name>/proposal.md
   - M  openspec/changes/<name>/tasks.md
   
   ### Source Files
   **Task 1: <task description>**
   - M  src/lib/components/search.svelte
   - A  src/lib/stores/search.ts
   
   **Task 3: <task description>**
   - M  src/routes/+page.svelte
   
   ### Unrelated Changes (not included)
   - M  src/lib/utils/format.ts
   - ??  tmp/scratch.js
   

   When step 4a populated other-session paths, insert an extra section between "Source Files" and "Unrelated Changes":

   ### Other Active Sessions (fail-closed; excluded even on "Include all")
   - M  layers/workstation/foo.ts  ← session abc123 / change workstation-report-ux-polish
   - ??  server/api/bar.ts          ← session def456 / change add-vending-stats
   

   If no tracking file was found, show a warning instead of the Source Files section:

   ### Source Files
   ⚠ No source file tracking data found.
   Only artifact files will be committed. Use `spectra task done` during apply to enable source file tracking.
   

   If there are no artifact files AND no tracked source files, inform the user that there is nothing to commit and STOP.

6. User confirmation

   Use the request_user_input 工具 to ask the user how to proceed.

   Options:

   • Commit as shown: Proceed with the displayed artifact + source files
   • Include all dirty files: Add all unrelated files to the commit as well
   • Customize: Let the user add or remove specific files from the commit set
   • Archive first, then commit together: Run archive before committing — archive file moves will be included in this commit

   If "Other Active Sessions" section is non-empty (step 4a populated it):

   • Commit as shown / Customize: other-session paths stay excluded; no re-confirm needed.
   • Include all dirty files: BEFORE proceeding, re-confirm with explicit list of other-session paths. Use request_user_input with options:
     • Skip other-session paths (recommended): commit only truly-unrelated dirty + artifact + source — leaves other sessions' WIP intact.
     • Force-include all (overwrites another session's commit opportunity): risky; only choose if user confirms they own the other session too.
     • Stop and resolve manually: abort commit; user investigates.

   If the user selects "Customize":

   • Show a numbered list of all dirty files (included and excluded)
   • Ask which files to add or remove
   • Re-display the updated commit plan for confirmation

   If the user selects "Archive first, then commit together":

   • Proceed to step 6a (Archive sub-flow) before continuing to step 7

6a. Archive sub-flow (only when the user selected "Archive first, then commit together")

This sub-flow executes three checks in sequence before returning to the main commit flow.

**6a-i. Incomplete task handling**

Read the tasks file at `openspec/changes/<name>/tasks.md`. Count `- [x]` (complete) and `- [ ]` (incomplete) checkboxes.

- If **all tasks are complete**: skip to 6a-ii.
- If **incomplete tasks exist**:
  - Display the list of incomplete tasks
  - Use the **request_user_input 工具** to ask: "These tasks are still incomplete. Mark all as complete before archiving?"
    - **Yes**: set a flag to pass `--mark-tasks-complete` to `spectra archive`
    - **No**: proceed without the flag (archive will continue with a warning)

  If **request_user_input 工具** is not available, ask the same question as plain text and wait for the user's response.

**6a-ii. Delta spec sync check**

Check whether delta specs exist at `openspec/changes/<name>/specs/`.

- If **no delta specs exist** (directory is empty or absent): skip to 6a-iii.
- If **delta specs exist**:
  - Use the **request_user_input 工具** to ask: "Delta specs found. Sync to main specs before archiving?"
    - **Yes**: run `spectra sync <name>` before proceeding
    - **No**: proceed without syncing

  If **request_user_input 工具** is not available, ask the same question as plain text and wait for the user's response.

**6a-iii. Archive execution and file collection**

Execute the archive:

```bash
spectra archive <name>          # without --mark-tasks-complete
spectra archive <name> --mark-tasks-complete  # if user chose to mark tasks complete in 6a-i
```

After archive completes successfully:

1. Re-run `git status --porcelain` to capture all file changes produced by the archive (deletions from `openspec/changes/<name>/`, additions in `openspec/archived/`)
2. Add these archive-related file changes to the commit set
3. Display an **updated commit plan** showing all sections:

```
## Updated Commit Plan: <change-name> (with archive)

### Change Artifacts (archived)
- D  docs/specs/changes/<name>/proposal.md
- D  docs/specs/changes/<name>/tasks.md
- ...

### Archived Files
- A  docs/specs/archived/<name>/proposal.md
- A  docs/specs/archived/<name>/tasks.md
- ...

### Source Files
(same as before)

### Spec Sync Changes (if sync was performed)
- M  docs/specs/specs/<spec-name>/spec.md
- ...
```

Then continue to step 7.

7. Generate commit message

Read the proposal file at openspec/changes/<name>/proposal.md. Extract the first sentence from the Why section (or Problem/Summary section if Why is absent).

Generate a message in this format:

spectra(<change-name>): <summary>

Change: <change-name>
Tasks: <completed>/<total> complete

If the archive sub-flow was executed (user selected "Archive first, then commit together"), add Archived: yes to the message body:

spectra(<change-name>): <summary>

Change: <change-name>
Tasks: <completed>/<total> complete
Archived: yes

Task progress comes from reading the tasks file and counting - [x] vs - [ ] checkboxes.

Show the generated message to the user and allow editing before proceeding.

8. Selective staging

   Stage each confirmed file individually:

   git add <file1>
   git add <file2>
   ...
   

   NEVER use git add . or git add -A. Each file must be staged explicitly.

9. Commit

   git commit --only -m "<message>" -- <file1> <file2> ...
   

   --only 以 pathspec 過濾 commit 範圍——別 session 預 staged 的檔案不會被捲入（4a partition 的 fail-closed 因此在機制上成立）。

10. Show result

    git log --oneline -1
    

    Display the commit hash and message to confirm.

Output On Success

## Committed: <change-name>

**Commit:** <short-hash> spectra(<change-name>): <summary>
**Files:** <N> files committed (<A> artifacts, <S> source files)
**Tasks:** <completed>/<total> complete

Output On Nothing To Commit

## Nothing to Commit

**Change:** <change-name>

No dirty files found for this change (no modified artifacts, no tracked source files).

Guardrails

• NEVER use git add . or git add -A — every file must be staged individually with git add <file>
• NEVER commit files the user hasn't confirmed — always show the file list and get explicit confirmation first
• Always show the full file list before committing — no silent staging
• If the tracking file is missing, warn but don't block — artifact-only commits are valid
• The "Unrelated Changes" section is informational only — these files are excluded by default
• If request_user_input 工具 is not available, ask the same questions as plain text and wait for the user's response
