setup-pre-commit makes the agent add a Husky pre-commit hook that runs lint-staged (Prettier on staged files), then your typecheck and test scripts. It detects npm, pnpm, yarn or bun from the lockfile, installs husky, lint-staged and prettier as devDependencies, and creates .husky/pre-commit, .lintstagedrc and a .prettierrc if none exists.

It starts when you ask for pre-commit hooks, Husky, lint-staged or commit-time formatting and testing. If the repo has no typecheck or test script, it leaves those lines out and tells you. Its last step stages the changed files and makes a commit, which runs the new hooks as a smoke test.

Good for

JavaScript and TypeScript developers who want formatting and checks on every commit
Teams adding Husky to a repo for the first time
Solo developers who want Prettier to run on staged files automatically

Permissions

Medium risk

It installs packages, edits package.json and makes a git commit on its own. Start from a clean working tree so the commit holds only the hook setup.

What it can do

Read your data
Create and change things
Delete things
Read-only mode

Watch out for

It stages and commits changed files for you
The last step stages all changed or created files and commits. Commit or stash unrelated work first.
It installs packages and runs npx
It adds three devDependencies and runs npx husky init. Check the package.json diff before you push.

Questions

What does setup-pre-commit set up?

Husky pre-commit hook, lint-staged running Prettier on staged files, a Prettier config if you lack one, and your typecheck and test scripts in the hook.

How do I install it?

Follow the install box at the top of the page. Then ask Claude to set up pre-commit hooks in your repo.

Which package managers does it support?

npm, pnpm, yarn and bun. It picks one from package-lock.json, pnpm-lock.yaml, yarn.lock or bun.lockb, and defaults to npm.

What if I have no typecheck or test script?

It leaves those lines out of the hook and tells you.

Will it commit for me?

Yes. The last step stages all changed or created files and commits with the message "Add pre-commit hooks (husky + lint-staged + prettier)". Stash unrelated changes first.

Does it need an API key?

SKILL.md asks for none. It runs npm-style installs and npx husky init in your repo.

Is it safe?

It edits package.json, installs three packages and makes a commit, all in your repo. Run it on a clean branch and review the diff before you push.
