To run static analysis across a Dart or Flutter project, analyze files to find compile and lint errors.

Write self-documenting code with clear naming and structure, adding minimal, evergreen comments only when necessary to explain complex logic. Use this skill when writing or reviewing any code that might need comments. When refactoring code to make it more self-explanatory through better naming and structure. When deciding whether to add or remove comments from existing code. When ensuring comments explain why something is done rather than what is being done. When reviewing code to remove outdated or temporary change-related comments. This skill applies to all programming languages and all types of code files.

Examples - "create class", "design module", "implement feature", "refactor code", "fix bug", "is this too complex", "apply SOLID", "keep it simple", "avoid over-engineering".

Diagnose and fix CI/CD failures by analyzing logs, reproducing locally, and applying fixes. Use when CI checks fail on pull requests.
