Git Commit Msg

Analyze the latest Git commit and amend it with a detailed structured message based on file status and diff stats. Use when the user asks to rewrite, improve, or standardize the most recent commit message, including after the commit is already created.

Git Commit Msg

Overview

Generate a detailed commit message for HEAD without loading broad repository context, preview it, and amend the latest commit. Detect whether the original HEAD is already on upstream and force-push with --force-with-lease when required.

Workflow

Ensure the repository is on a normal branch (not detached HEAD).
Run:

scripts/amend_latest_commit_message.sh

Review the message preview shown by the script.
Confirm the amend prompt to update HEAD.

Message Format

Generate a structured message with:

A concise title line.
Summary section.
Files Changed section grouped by Added, Modified, Deleted, and Renamed.
Stats section using git shortstat output.
Notes section documenting that the message was derived from latest commit metadata.

Options

Use optional flags when needed:

--yes: skip interactive confirmation.
--no-push: never push, even when old HEAD was on upstream.
--max-files N: cap file entries shown per section (default 10).

Safety and Token Efficiency

Keep analysis strictly to latest-commit metadata:

git diff-tree --name-status for file status classification.
git show --shortstat for compact statistics.

Do not scan the full repo or load large code context to generate the message.
