+# Linter Policeman
+
+When to use this skill
+
+- Use before committing or when tests show linting/style failures.
+- Triggered by prompts to run or autofix style issues across the repo.
+
+Instructions
+
+1. First Step: Ensure `eslint` and `prettier` are installed and `package.json` contains `lint` and `format` scripts.
+
+2. Second Step: Run `npm run lint -- --fix` and `npm run format` and report files changed plus any remaining errors that require manual attention.
+
+3. Third Step: Suggest rule tweaks or suppression only when justified; avoid disabling rules globally.
+
+Examples
+
+- `npm run lint` -> list of files with errors; `npm run lint -- --fix` to autocorrect.
+
+Notes
+
+- Encourage using pre-commit hooks (Husky + lint-staged) so formatting occurs automatically.
