Skill: Comments
Use this when reviewing a diff for comment hygiene: too many, too few in the wrong places, or — worst — comments that lie about what the code does.
Rules
Each rule in this domain is its own sub-skill. Scan the diff for violations of every rule below.
| Rule | Triggers on |
|---|---|
| over-commenting | comments that explain what self-documenting code already says |
| wrong-kind-of-comment | comments describing what instead of why |
| inaccurate-comments | comments or docstrings that no longer match the code |
| missing-deferred-removal-markers | compatibility shim kept without a deferred-removal comment |
| comment-typos | typos and obvious errors in comment text |

How to report
Cite the exact file and line, describe the problem, and classify severity (high / medium / low). Inaccurate comments that will mislead a future maintainer, and missing deferred-removal markers on compatibility shims, are high. Over-commenting and what-not-why narration are typically low. Full marks are warranted when comments are absent or limited to explaining the non-obvious why — do not invent findings.
Return two sections:
Findings
A bullet list, one per violation, in this format:
- <High/Medium/Low> | <Finding Title>: <one-sentence explanation grounded in the diff>
Recommendations
One recommendation per finding above, numbered sequentially within this skill. Each recommendation MUST contain all four sections below.
### Recommendation N: <short title>
**Problem**: Describe the specific issue in the diff.
**Reason**: Explain why this is a problem — what goes wrong or degrades over time.
**Solution**: Give a concrete, actionable fix. Where possible, show a before/after code snippet.
**Locations**: List every place this issue occurs, one per line, in `filepath:line` form.
