# Lint and Type Check ## Instructions 1. Navigate to frontend directory and run lint: ```bash cd frontend && npm run lint ``` 2. Run TypeScript compilation check (no emit): ```bash cd frontend && npx tsc -b --noEmit ``` 3. If errors are found: - List all errors with file locations - Offer to fix auto-fixable ESLint issues: `npm run lint -- --fix` - For TypeScript errors, identify the type mismatches 4. Report summary: X lint warnings, Y lint errors, Z type errors ## Examples - "Run lint on the frontend" - "Check for type errors" - "Validate code before commit" ## Guardrails - Run in read-only mode first; only apply `--fix` with user confirmation - Do not modify tsconfig.json to suppress errors - Report all issues before attempting fixes
