git-commit-message

name	git-commit-message
description	Draft a commit message from staged changes. Matches the style of recent commits in the repo, emphasizes why over what, and does not run `git commit`.

Commit Message

Generate a commit message from staged changes.

Task

1. Run git diff --staged and git log --oneline -20
2. Draft a commit message matching the style of recent commits

Rules

• Focus on why, not what
• Subject line under 72 characters; add bullet-point body for multiple logical units
• If $ARGUMENTS is provided, use it as additional context

Output

Do NOT run git commit. Write the draft to /tmp/commit-message.md as the canonical artifact — chat rendering can introduce trailing whitespace invisibly, so the file (not the chat output) is the source of truth. Verify cleanliness and copy to the clipboard:

grep -nE '[[:blank:]]+$' /tmp/commit-message.md && echo "FAIL: trailing whitespace" || pbcopy < /tmp/commit-message.md

Also show the same content in a single fenced code block for in-chat preview. Do not leave trailing whitespace on any line.
