Use whichever is present. Default to npm if unclear. Install as devDependencies: This creates .husky/ dir and adds prepare: "husky" to package.json. Write this file (no shebang needed for Husky v9+): Adapt: Replace npm with detected package manager. If repo has no typecheck or test script in package.json, omit those lines and tell the user.

Use these defaults: [ ] .husky/pre-commit exists and is executable [ ] .lintstagedrc exists [ ] prepare script in package.json is "husky" [ ] prettier config exists [ ] Run npx lint-staged to verify it works Stage all changed/created files and commit with message: Add pre-commit hooks (husky + lint-staged + prettier) This will run through the new pre-commit hooks: a good smoke test that everything works.
