Full skill instructions

Lint and Type Check

Instructions

  1. Navigate to frontend directory and run lint:

    cd frontend && npm run lint

  2. Run TypeScript compilation check (no emit):

    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
