Create new Claude Code skills with proper structure, documentation, and best practices. Use when building custom skills for specific domains, workflows, or organizational needs.

Write self-documenting code with minimal, evergreen comments that explain WHY rather than WHAT, avoiding temporary change notes or obvious descriptions. Use this skill when adding comments to any code file to ensure comments provide value by explaining complex logic, business rules, or non-obvious decisions rather than describing what the code does. Apply this skill when writing code that needs clarification, when documenting complex algorithms or business logic, or when removing outdated or redundant comments that describe obvious operations. This skill prioritizes writing clear, expressive code through meaningful naming and structure that minimizes the need for comments, ensures any comments added are helpful and explain intent or reasoning, and avoids leaving comments about recent changes, temporary fixes, or information that belongs in commit messages or documentation.
