Let Claude Write Your Conventional Commit Messages

Writing consistent, meaningful commit messages is one of those things everyone agrees is good practice and almost nobody does consistently. Let Claude handle it — pipe your staged diff and get a properly formatted message back.

git diff --staged | claude -p "Write a conventional commit message for these changes. 
Output only the commit message, nothing else."

Use it directly in a git commit call:

git commit -m "$(git diff --staged | claude -p 'Write a conventional commit message. Output only the message.')"

Add a shell alias to make it a one-keystroke habit:

# Add to ~/.zshrc or ~/.bashrc
alias gcm='git commit -m "$(git diff --staged | claude -p "Write a conventional commit message for these staged changes. Output only the message with no explanation.")"'

Now you just stage your changes and run gcm:

git add src/auth/
gcm
# → feat(auth): add refresh token rotation with sliding expiry

You can extend the prompt to follow your team's specific conventions — mention your ticket prefix format, scope naming rules, or character limits and Claude will follow them.

Commit messages are documentation for your future self and your team.

Never write fix stuff again — make Claude write commit messages the way they were meant to be written.
