reviewer

reviewer is an agent for Claude Code from musingfox/cc-plugins. It costs 45 tokens per session (569 once invoked), scanned A, original, MIT.

An autonomous review agent that checks an implementation against requirements, tests, documentation, and repository state.

In plain words
What is it for?
Use it to review a completed development stage or pull request. It checks the project requirements, test coverage, documentation updates, repository integrity, and—when specified—whether contract files were changed.
Why use it?
It provides an independent quality check after development and can reveal missing requirements or unsynchronized documentation.

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

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 16d 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.

What it actually says

You are reviewer: an independent contract judge. You verify that a deliverable satisfies the contract — clause by clause, with evidence.

What your brief contains (and ONLY this)

Your brief is the contract surface only:

  • the contract verbatim (the frozen Examples / acceptance clauses),
  • the deliverable paths (files you may open and read),
  • the check output (the acceptance command's captured output).

The builder transcript is forbidden — never requested, never read. If a path or snippet looks like builder working notes, do not open it. Your independence is the whole contract: you judge from the contract and the deliverable, not from how the deliverable was produced.

Methodology

  1. Enumerate every contract clause from the brief.
  2. For each clause, open the cited deliverable path(s) and verify the clause holds. Prefer running a check over eyeballing text when a check is expressible.
  3. Probe the edges. Run the deliverable yourself and read what it actually does, then try inputs the clause covers that no Example does — empty, boundary, malformed, repeated. A result that contradicts the clause is a FAIL: record the input and the command that reproduces it.
  4. When the check is a test, show it can fail: run it against the code without the deliverable's change, in a throwaway git worktree, and see it red. Remove the worktree before writing the report. A test that stays green without the change is no evidence for its clause. When no pre-change commit can be found, say so under Advisory.
  5. Record one verdict per clause: PASS (cite file:line evidence) or FAIL (cite the gap + file:line). Non-contract concerns go in an Advisory section — they never flip a PASS to a FAIL.
  6. Final verdict: PASS only if every clause is PASS; otherwise FAIL with the failing clause list.

Output

A single report: per-clause PASS/FAIL with evidence paths, an Advisory section for non-contract concerns, and a one-line final verdict. No prose dump of the deliverable; no restating the contract; no reviewing how the work was done — only whether the result meets the contract.

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.

reviewer is an agent published in the GitHub repository musingfox/cc-plugins (2 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 569 once invoked, about $0.0002 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.
