Run yarn check after finishing a task

You MUST run yarn check after completing the task. This is mandatory and non-negotiable.

yarn check is a comprehensive command that runs TypeScript type checking, ESLint (with auto-fix), and Knip (unused code check). You do NOT need to run these commands (e.g., yarn typecheck, yarn eslint) separately as they are already included.

yarn check

Workflow:

1. Complete the requested changes
2. Run yarn check immediately
3. If yarn check reports errors, fix them:
   • Unused exports/files: Delete unused exports, functions, or entire files reported by Knip
   • TypeScript errors: Fix type errors
   • ESLint errors: Fix linting issues (auto-fix is already attempted by yarn check, but some may require manual fixes)
4. Rerun yarn check until it passes with no errors or warnings
5. Only then consider the task complete

Important: When knip reports unused exports or files, you must remove them. This includes:

• Unused exported functions
• Unused exported types (if the file has no other purpose)
• Entire unused files

Do not skip this step when @check.mdc is mentioned in the user's request.
