What it does

When installed, the agent can configure a JavaScript or TypeScript project so that every git commit is automatically checked. It installs Husky (a tool that runs scripts at git events), lint-staged (which runs formatters only on staged files) and Prettier (a code formatter), then writes a pre-commit hook that runs formatting, a typecheck script and a test script. The agent detects which package manager the repo uses (npm, pnpm, yarn or bun) and adapts the commands, and it commits the result as a smoke test.

Great for

  • Developers starting a JavaScript or TypeScript project who want consistent formatting and checks on every commit
  • Teams standardising commit-time quality gates across a repo that lacks Husky setup
  • Maintainers who already have typecheck and test scripts in package.json

Skip it if

  • Repos without package.json or a Node.js toolchain, where the setup steps do not apply
  • Projects that already have a configured hook system or Prettier config, since the skill may conflict with or overwrite existing setup and commits made through it run the full test suite, which can be slow
  • Non-technical users who would not be able to review the changes or recover if a commit is blocked or misconfigured

Try asking

  • “Set up Husky and lint-staged with Prettier in this repo”
  • “Add a pre-commit hook that runs typecheck and tests before each commit”
  • “Configure lint-staged so only staged files get formatted on commit”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Review the generated .husky/pre-commit and .lintstagedrc before the agent commits, and check that the repo has typecheck and test scripts first
  • Ask the agent to skip the automatic commit step if you want to inspect changes yourself
  • Note that the skill's commit step will trigger the new hooks, so make sure the tests pass beforehand
