Every section is lean and table-driven. No unnecessary explanations of what comments are or how JavaScript works. The skill assumes Claude's competence and delivers only the decision framework and examples needed.

Provides concrete, executable JavaScript examples showing both good and bad patterns. The decision table ('When to Comment') gives specific, actionable guidance for each situation. The JSDoc example is copy-paste ready.

This is a single-purpose instructional skill (commenting guidelines), not a multi-step destructive workflow. The decision table provides a clear, unambiguous sequence for deciding when and how to comment, and the checklist at the end serves as a validation checkpoint for reviewing comments.

For a skill under 50 lines with no need for external references, the content is well-organized into clearly labeled sections (When to Comment, Examples, Public APIs, Annotation Tags, Anti-Patterns, Checklist) that allow quick scanning and progressive depth.

Lists multiple specific concrete actions and topics: writing self-explanatory code, when to comment (WHY not WHAT), anti-patterns to avoid, annotation tags, and public API documentation. These are concrete, actionable areas.

Clearly answers both 'what' (guidelines for self-explanatory code with minimal comments, covering WHY not WHAT, anti-patterns, annotation tags, public API docs) and 'when' (explicit 'Use when' clause listing writing/reviewing code comments, docstrings, TODO/FIXME tags, code readability, inline comments).

Includes strong natural keywords users would say: 'code comments', 'docstrings', 'TODO/FIXME tags', 'code readability', 'inline comments', 'reviewing code'. These cover common variations of how users would phrase requests about commenting practices.

Occupies a clear niche around code commenting practices and documentation style. The specific triggers like 'TODO/FIXME tags', 'docstrings', and 'inline comments' are distinct enough to avoid conflicts with general coding or documentation skills.
