Full skill instructions

Lint Check

This skill performs linting and style checks on YARS code before committing, as required by project guidelines.

Usage

Automatically invoked when:

  • User asks to check linting or code style
  • Before creating commits or pull requests
  • After writing new code
  • As part of pre-commit validation

Checks Performed

1. Compiler Warnings Check

cd build
cmake .. && make -j4 2>&1 | tee build-warnings.txt
grep -i "warning:" build-warnings.txt

2. Namespace Usage Check

# Verify new files use namespace yars
grep -r "namespace yars" src/ --include="*.h" --include="*.cpp"

3. Modern C++ Patterns

# Check for NULL usage (should use nullptr)
grep -r "NULL" src/ --include="*.h" --include="*.cpp" | grep -v "nullptr"

# Check for raw pointer news that might need smart pointers
grep -r "new " src/ --include="*.cpp" | grep -v "unique_ptr" | grep -v "shared_ptr"

4. Observer Pattern Check

# Track remaining observer pattern usage
grep -r "Observable\|Observer" src/ --include="*.h" --include="*.cpp" | grep -v backup

Success Criteria

  • ✅ No compiler warnings
  • ✅ New code uses namespace yars {}
  • ✅ No NULL usage (nullptr instead)
  • ✅ Raw pointers properly justified
  • ✅ Observer pattern not introduced in new code

Reporting

Reports should include:

  • Count of any warnings found
  • Files with potential issues
  • Specific lines that need attention
  • Suggestions for fixes

Notes

  • Must pass before code can be committed
  • Some warnings may be acceptable (document why)
  • Focus on new code, not legacy issues
  • Integrate with git pre-commit hooks if possible
