Every section earns its place by teaching non-obvious judgment calls about commenting. No padding or explanation of concepts Claude already knows—it jumps straight into actionable criteria and examples.

Provides concrete, executable examples throughout—the 'rename test', the reconnect() worked example, and the output format template are all copy-paste ready and demonstrate exactly what good vs bad comments look like.

For a judgment-based skill (not a multi-step destructive operation), the workflow is crystal clear: evaluate against the tables, apply the rename test, use the output format. The single-task nature is handled with unambiguous guidance.

Well-organized with clear sections (what deserves comments, what doesn't, the test, worked example, docstrings, do-nots, output format). At ~100 lines with no need for external references, the self-contained structure is appropriate.

Lists specific concrete actions: 'Generates code comments that explain non-obvious intent, constraints, and tradeoffs' with clear differentiation from what it doesn't do ('not what the code already says').

Clearly answers both what ('Generates code comments that explain non-obvious intent, constraints, and tradeoffs') and when ('Use when code is correct but opaque, when documenting for future maintainers, or when a function's why is harder to see than its what').

Includes relevant terms like 'code comments', 'documenting', 'maintainers', but misses common variations users might say like 'add comments', 'explain code', 'annotate', or 'documentation'.

Highly distinctive with clear niche focus on 'why' over 'what', specifically targeting non-obvious intent and tradeoffs. Unlikely to conflict with general code documentation or explanation skills.
