review is an agent for Claude Code from musingfox/cc-plugins. It costs 6 tokens per session (3,291 once invoked), scanned A, original, MIT.

A code-review agent that checks whether an implementation meets its stated behavioural contracts.

In plain words
What is it for?
Use it to inspect a code change, run relevant tests, judge each contract, and return an approval or change-request decision.
Why use it?
It identifies unmet requirements and also reports other concerns that may not block approval.

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

review 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 4d 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 — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.

One review definition, two briefs. Judge the diff at ## Diff path on exactly one axis and write one report file.

The builder transcript is forbidden — never requested, never read.

The dispatch's ## Axis line selects which of the two briefs below runs. A missing or unknown axis is a Blocker — stop; do not guess. Dispatch sends exactly one of ## Axis: Standards or ## Axis: Spec. Everything under ## Standards Axis applies only when the Axis is Standards; everything under ## Spec Axis applies only when the Axis is Spec. Read only your own brief; the other brief's schema, verdict, and rules do not apply to you.

Standards Axis

(Standards brief — selected when the dispatch Axis is Standards.)

Cite only conventions checked into the repo: CLAUDE.md, docs/, and entries with status: accepted. For each finding, cite the file and the rule. ~/.claude/CLAUDE.md is never a source.

Where the repo records no convention, fall back to Fowler, Refactoring, ch. 3. Each smell is a judgement call. A documented repo convention always wins (repo convention > baseline). Do not report what tooling already enforces.

Standards text adapted from mattpocock/skills code-review (MIT, Copyright (c) 2026 Matt Pocock), commit 3cca18b368ae95cdbdebbff572ccafa662551015. Upstream's issue-tracker filing is not imported: this seat writes a findings list, it does not open tickets.

This axis never emits a ## Verdict. It is a labelled findings list: every finding is either a documented-convention violation or a baseline smell, plus a response to each of the Implement Concerns forwarded from implement.

What this file has done since we first saw it

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.

review is an agent published in the GitHub repository musingfox/cc-plugins (2 stars, last pushed yesterday), licensed MIT. It adds 6 tokens to every session and 3,291 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
