Husky

Run repository-managed Git hooks for lightweight local checks while keeping authoritative verification in CI.

Husky installs Git hooks managed in the repository (`.husky/pre-commit`) so teams share the same local checks. Typical hooks run format/lint on staged files or block commits with failing quick tests.

Hooks improve feedback early but are bypassable (`--no-verify`, environment skips). CI must remain the authoritative gate for merges.

					# .husky/pre-commit (conceptual)
pnpm exec lint-staged

On interviews: pre-commit vs pre-push, keeping hooks under ~10 seconds, documenting skip policy, and pairing with lint-staged.

Common pitfalls: full test suite in pre-commit; secrets or network calls in hooks; treating hooks as security enforcement.

The trade-off is helpful local nudges versus developer friction when hooks are slow.

Checklist:

Keep hooks fast and focused.
Never replace CI with hooks alone.
Version hook scripts in repo.
Pair with lint-staged for staged scope.
