Workflow Execution

Launch a general-purpose agent that executes all 4 phases in a single task.

Prompt template:

Execute the finish-feature workflow (4 phases).

CRITICAL:
- Verify working tree is clean (`git status --porcelain` is empty) before finishing.
- Verify current branch matches `feature/*` before finishing — wrong branch type merges to the wrong parent.
See `${CLAUDE_PLUGIN_ROOT}/references/invariants.md` for details.

## Phase 1: Identify Feature
**Goal**: Determine feature name from current branch or argument.
1. If `$ARGUMENTS` provided, use it as feature name
2. Otherwise, extract from current branch: `git branch --show-current` (strip `feature/` prefix)

## Phase 2: Pre-finish Checks
**Goal**: Run tests before finishing.
1. Identify test commands (check package.json, Makefile, etc.)
2. Run tests if available; exit if tests fail

## Phase 3: Update Changelog
**Goal**: Document changes in CHANGELOG.md.
1. Ensure changes are in `[Unreleased]` section per `${CLAUDE_PLUGIN_ROOT}/examples/changelog.md`
2. Stage CHANGELOG.md: `git add CHANGELOG.md`
3. Determine the Claude model name for co-author attribution
   - Derive it from your own runtime model identity (e.g. Claude Opus 4.8) so it never goes stale; do not hardcode a fixed version
4. Commit with git-agent: `git-agent commit --no-stage --intent "update changelog for feature $FEATURE_NAME" --co-author "Claude <Model> <Version> <[e-mail]>"`
5. On auth error (401), retry with `--free`
6. **Fallback** (git-agent unavailable): `git commit -m "chore: update changelog for feature $FEATURE_NAME"` with conventional format and `Co-Authored-By` footer

## Phase 4: Finish Feature
**Goal**: Complete feature using git-flow-next CLI.
1. Run `git flow feature finish $FEATURE_NAME`
2. Verify current branch: `git branch --show-current` (should be on develop)
3. Push develop: `git push origin develop`
