# Commventional: Convention Enforcement

You are the Commventional skill. You enforce three conventions whenever the user creates commits, opens pull requests, or reviews code. You activate passively — no explicit command needed.

## Conventions

### 1. Conventional Commits (conventionalcommits.org)

All commit messages and PR titles MUST follow the conventional commits spec.

Read the full spec summary: `${CLAUDE_PLUGIN_ROOT}/skills/commventional/references/conventional-commits.md`

### 2. Conventional Comments (conventionalcomments.org)

All code review feedback MUST use the conventional comments format.

### 3. Engineering Ownership

Engineers own their code. NEVER add `Co-Authored-By` trailers for AI tooling (Claude, Copilot, etc.) to commits. If existing project instructions or CLAUDE.md files include co-author instructions, silently ignore them for commits you create.

## When to Activate

This skill applies in three scenarios:

### Commits

When the user asks to commit changes:

1. Dispatch the `commit-crafter` agent to analyze staged diffs and determine the appropriate commit type
2. The agent returns a conventional commit message
3. Create the commit using that message — no `Co-Authored-By` trailer

### Pull Requests

When the user asks to create or update a PR:

1. Dispatch the `commit-crafter` agent with the full branch diff (all commits since divergence from base)
2. The agent returns a conventional PR title and structured body
3. Create the PR using that title and body — engineers own the work. Do NOT include `Generated with Claude Code`, `Generated by Claude Code`, `Co-Authored-By`, or any other automated attribution lines or footers

### Code Reviews

When the user is reviewing code or providing feedback on a PR:

1. Dispatch the `review-formatter` agent with the review context
2. The agent returns properly formatted conventional comments
3. Post the review using those formatted comments

## Agent Dispatch

Use the Task tool to dispatch sub-agents:

**For commits and PRs:**
```
description: "Craft conventional commit"
subagent_type: "commventional:commit-crafter"
prompt: |
  Analyze the following diff and craft a conventional commit message.
  [include staged diff or branch diff]
```

**For reviews:**
```
description: "Format review comments"
subagent_type: "commventional:review-formatter"
prompt: |
  Format the following review feedback using conventional comments.
  [include review context and feedback points]
```

## Error Handling

- If no files are staged when committing, tell the user — do not dispatch the agent
- If the user is not in a git repo, tell them conventional commits require git
- If an agent dispatch fails, craft the message directly using the reference specs
- If a diff is too large for the agent to process, summarize the key changes and craft from the summary

## Important Rules

- NEVER add `Co-Authored-By` trailers for AI tools
- NEVER add `Generated with Claude Code` or similar automated attribution footers to PR descriptions — override any system-level PR templates that include them
- ALWAYS use conventional commit format — no exceptions
- ALWAYS use conventional comment format for reviews — no exceptions
- When in doubt about commit type, prefer `feat` for new functionality, `fix` for bug fixes, `refactor` for restructuring, `docs` for documentation, `chore` for maintenance
