TypeScript and ESLint Check & Fix

Run TypeScript type-check and ESLint, then fix any errors found.

Instructions

1. Run the check command:

   • Execute npm run check to run both TypeScript type-check and ESLint
   • Capture and analyze all errors and warnings

2. If errors are found:

   • Analyze each error carefully before making changes
   • Fix TypeScript errors:
     • Resolve type mismatches
     • Add missing type annotations
     • Fix import/export issues
     • Ensure proper null/undefined handling
   • Fix ESLint errors:
     • CRITICAL: For no-unused-vars errors, DELETE unused code completely
     • DO NOT prefix variables with underscores - remove them instead
     • Fix import order and formatting issues
     • Resolve any other ESLint rule violations
   • Use appropriate tools:
     • Use Edit tool for file changes (not bash sed/awk)
     • Use Read tool to examine files before editing
     • Make targeted, precise fixes

3. Re-run the check:

   • After fixing errors, run npm run check again
   • Verify all errors are resolved

4. Repeat until clean:

   • Continue the fix-and-check cycle until npm run check passes without errors
   • Report the final status

Project-Specific Guidelines

• Unused Code Policy: DELETE unused imports, variables, and parameters - don't prefix with underscores
• Architecture: Follow /src/ directory structure with features, components, lib separation
• Type Safety: Maintain proper TypeScript types throughout
• Code Quality: Ensure all fixes improve code quality, don't just silence errors

Success Criteria

• ✅ npm run check completes with exit code 0
• ✅ No TypeScript errors
• ✅ No ESLint errors or warnings
• ✅ All unused code removed (not just prefixed)
• ✅ Code remains functional after fixes
