Scan recently written or edited code and remove comments that do not earn their place — narration, step markers, task/PR references, commented-out blocks, decorative banners. Use this skill after finishing a non-trivial code change, when reviewing a diff for comment hygiene, when the user mentions noisy or redundant comments, or proactively before declaring a coding task complete. Defer to the `comments` rule for what makes a comment worth keeping.

Comments Cleanup
Scan the diff you just produced and strip comments that the code already carries. The comments rule has the long-form criteria and examples; this skill is the cleanup procedure.
Procedure
Pull the diff.git diff for unstaged work, git diff --staged for staged. Focus on +-lines that introduced comments.
For each new comment, ask one question — would a competent reader miss anything if this comment were removed? If the answer is no, delete the comment.
Tighten what remains. A comment that stays should describe why, fit on one line where possible, and use the language's doc-comment syntax for public APIs only.
Categories to delete on sight
Narration — restates what the code does (// increment counter, // loop through users, // validate user).
Step markers — planning artefacts (// Step 1: fetch users, // now we will…, // AI thought: …).
Task / PR / caller references (// added for ticket X, // used by Y) — that context belongs in the commit message.
Commented-out code — git keeps the history.
Decorative banners (// ===== HELPERS =====) when nothing else in the file uses them.
Apologies (// hacky but works) — either fix the code or open a tracked issue and link it.
Untracked TODO / FIXME — pair every marker with an owner or an issue, or resolve it now.
Categories to keep
Hidden constraint — a non-obvious invariant, ordering requirement, or performance assumption.
External quirk — API behaviour, browser bug, platform-specific oddity (name the system).
Workaround — a fix for a tracked upstream issue (link it).
Surprise — behaviour that would make a reasonable reader pause.
Public API contract — inputs, outputs, errors, side effects via ///, /** */, or docstrings.
Self-check before finishing
Diff scanned end-to-end, including test files.
No // Step N, no // loop, no // AI thought, no commented-out blocks.
Every remaining TODO / FIXME has an owner or issue.
Comment density matches the surrounding files (scan 5–10 nearby).
Report what was removed and what was kept, with a one-line reason per surviving comment when it isn't obvious.
