draft-commit-message

Draft a conventional commit message that matches the change summary provided by the user.

Requirements

• Use the Conventional Commits format: type(scope): summary.
• Use the imperative mood in the summary (for example, feat, fix, refactor).
• The supported types are bump, feat, fix, docs, refactor, test, ci, chore, perf, and revert.
• The entire first line (including type and scope) must not exceed 72 characters.
• Do not wrap the summary line.
• If there are breaking changes, include a BREAKING CHANGE: footer.
• Always use English.

Script

• Run git-diff.sh before generating a commit message.
• From repository root, run:
  • bash skills/draft-commit-message/scripts/git-diff.sh
  • Optional scoped analysis: bash skills/draft-commit-message/scripts/git-diff.sh <path>
• Use the script output as the primary source of truth for determining the commit type and summary.
• The script shows both staged and unstaged status, diff stats, full diffs, and untracked files.
• Prefer analyzing staged changes when drafting the commit message.
• If the script fails, fallback to git --no-pager diff --cached.

Output Contract

• Return commit message text only (no explanation) unless user asks for reasoning.
• Follow the exact output format in REFERENCE.md:
  • Subject: type(scope): summary (<=72 chars)
  • Optional body: concise bullet points
  • Optional footer: BREAKING CHANGE: ...
