Comment Quality Reviewer

Finds code comments written as change history and rewrites them into durable invariants or rationale.

Dev & CodingIntermediate★ 421⑂ 44AI score 9/10Last updated: Sep 20, 2026

What it does

  • Scans only the files you point it at, flagging comments whose meaning depends on an unstated earlier revision ("now uses JWT", "fixed retry handling", "faster than before").
  • Treats references/temporal-keywords.md as a candidate list, not a verdict: it checks comment syntax and surrounding code, and skips string literals and identifiers.
  • Preserves legal headers, generated markers, required API/version annotations, and deprecation notices that still carry a useful migration contract.
  • For each finding: read the enclosing function → decide whether the durable fact is behavior, rationale, or neither → rewrite or delete → report file:line, original, replacement, and the inferred invariant.
  • Refuses to invent rationale from code shape; ambiguous cases are left alone and reported. Edits are applied only on request, then re-read.

Who it's for

  • Developers inheriting a legacy codebase where comments no longer match behavior.
  • Tech leads adding comment hygiene to a review checklist.
  • Any engineer, in any language or stack, reducing documentation debt.

Examples

  1. "Review comments in src/auth" → suggests turning "// now uses JWT instead of sessions" into "// Tokens are RS256-signed JWTs; sessions are unused".
  2. Scan only files in a PR diff and emit a file:line list to paste into review comments.
  3. For "// fixed the race condition", if no durable rationale can be inferred, leave it and flag the ambiguity instead of guessing.

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/code-quality/comment-quality folder from the GitHub repo notque/vexjoy-agent into my ~/.claude/skills/comment-quality/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/notque/vexjoy-agent.git /tmp/vexjoy-agent && mkdir -p ~/.claude/skills && cp -r /tmp/vexjoy-agent/skills/code-quality/comment-quality ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/notque/vexjoy-agent.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the whole skill folder (so the references file comes along): cp -r vexjoy-agent/skills/code-quality/comment-quality ~/.claude/skills/
  5. Verify ~/.claude/skills/comment-quality/ contains SKILL.md and references/temporal-keywords.md.
  6. Restart Claude Code and ask something like "review the comment quality of these files". Note the skill sets user-invocable: false, so it is normally routed in by a broader code-review flow rather than called by name.
