Commit Message

Draft a Conventional Commit message from staged changes.

Critical Constraints

• Use only staged changes (--cached / staged SCM state) as input.
• Resolve and use the repository root for all SCM calls.
• If no staged changes exist after one retry, stop and inform the user.
• Always include an AI-assistant: <AGENT> footer.
• Output only the final commit message in one markdown code block.

Workflow

1. Resolve repository root. Prefer workspace root when known; otherwise run git rev-parse --show-toplevel.
2. Retrieve staged changes. Prefer get_changed_files with repositoryPath: <repo-root> and staged state. If that tool is unavailable, use SCM tooling with explicit repo context. If SCM tooling is unavailable, use git -C <repo-root> diff --cached.
3. Validate staged content exists. If empty, retry once with explicit repo root; if still empty, inform user and stop.
4. Analyze the staged diff. Identify changed files, behavior impact, logical scope, and likely commit type.
5. Incorporate user arguments/context when provided. Preserve explicit issue refs and constraints from user input.
6. Draft the commit message using references/conventional-commit-rules.md.
7. Return only the final message in a fenced code block, ready for git commit -F -.
