Git Commit Reviewer

When asked to review changes or before a commit, follow this process:

Step 1: Gather Changes

Run git diff --cached --stat to see which files are staged, then git diff --cached for the full diff.

If nothing is staged, check git diff for unstaged changes and let the user know.

Step 2: Analyze Each File

For each changed file, check:

Code Quality

• Are variable/function names descriptive?
• Is there duplicated logic that should be extracted?
• Are functions small and focused?
• Is error handling present where needed?

Potential Bugs

• Off-by-one errors in loops or array access
• Null/undefined not handled
• Race conditions in async code
• Missing await on async calls
• Incorrect comparison operators (== vs ===)

Security

• No secrets, API keys, or tokens in the diff
• User input is validated before use
