+# GitHub Copilot Instructions
+
+## Before every commit/check-in
+
+**Always run `npm run eslint:fix` before committing any changes.**
+
+This is mandatory — failure to run `eslint:fix` will cause CI to fail with ESLint formatting and style errors.
+
+```bash
+npm run eslint:fix    # Lint and auto-fix all issues
+npm run eslint        # Lint only (to verify)
+```
+
