Ask Claude to Write and Install Git Hooks for Your Project

Git hooks automate quality checks so broken code never leaves your machine. But writing the scripts is annoying — getting the exit codes right, handling edge cases, and making them fast enough that nobody disables them. Claude handles all of that.

Write a pre-commit hook that runs the linter on staged files only. 
It should fail the commit if there are lint errors and show a clear message 
about how to fix them. Install it in .git/hooks/.

Claude writes the hook, makes it executable, and tests it. The hook runs your actual lint command (from CLAUDE.md or your package scripts) on only the staged files, not the whole repo — fast enough to run on every commit.

Common hooks Claude can set up:

# Pre-commit: lint and format
Write a pre-commit hook that runs the formatter on staged files 
and auto-stages the formatted changes. If the linter still finds 
issues after formatting, block the commit.

# Commit-msg: enforce conventional commits
Write a commit-msg hook that validates the commit message 
follows conventional commit format (feat/fix/refactor/docs). 
Reject the commit with a helpful error if the format is wrong.

# Pre-push: run tests
Write a pre-push hook that runs the test suite before allowing 
a push. Skip it for WIP branches that start with "wip/".

# Post-merge: install dependencies
Write a post-merge hook that checks if package.json or 
composer.json changed and automatically runs the install 
command if dependencies were updated.

If your project uses a hook manager like Husky, Lefthook, or Captain Hook:

Set up Husky with a pre-commit hook that runs lint-staged 
and a commit-msg hook that validates conventional commits. 
Configure lint-staged to run the right formatter per file type.

Claude reads your project's tooling and writes hooks that use the correct commands, handle your monorepo structure if needed, and exit cleanly on success.

Good habits are easier when they're automated — let Claude write the git hooks that enforce your standards before code leaves your machine.
