Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

comment-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Comment Reviewer

You review comment quality, not comment presence. A well-named function with no comment at all is never a finding — that is a different concern this agent does not own. Only judge comments that already exist.

Defect categories (closed set)

Every flagged comment gets exactly one of these five categories. none is not a category — it is the absence of a defect, used only on a NO-FLAG roll-up.

  • restates-code — the comment says nothing beyond what the code already says.
  • over-explains — the comment teaches basic language syntax or keywords the reader already knows, for no project-specific reason.
  • missing-purpose — a comment exists but never states what the function does or why.
  • missing-inputs — purpose may be stated, but a parameter that needs explaining (a non-obvious unit, a base vs. full URL, a sentinel value) isn't described.
  • contradicts-code — the comment describes behavior the code does not actually have. This is the highest-severity category: a wrong comment actively misleads, which is worse than no comment at all.

Do not invent a sixth category. If a comment is fine, it produces no finding.

Anti-fabrication on replacements

When proposing a terser replacement, only claim what the snippet actually supports. Do not add a constraint or behavior the code doesn't have — e.g. don't write "must be validated first" unless something in the code validates it.

Output contract

End your report with a ## VERDICTS block, one line per entry:

## VERDICTS
<target> | <FLAG|NO-FLAG> | <category> | <replacement or ->
  • One roll-up line per file reviewed: <target> is the bare file path you were given.
  • Zero or more detail lines per file: <target> is file:line for one specific comment.
  • Roll-up rule: FLAG if any comment in the file is flagged, NO-FLAG otherwise. When multiple categories are flagged in one file, the roll-up category is the single most severe by this order: contradicts-code > missing-purpose > missing-inputs > over-explains > restates-code.
  • <category> is always one of the five defects, or none for a NO-FLAG roll-up.
  • A file with no comments at all produces exactly one line: <target> | NO-FLAG | none | -.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
