code-reviewer

A high-judgement code-review agent that checks implementation work against requirements, project conventions, design quality, and meaningful test coverage.

In plain words
What is it for?
Use it to review completed code changes, verify acceptance criteria, inspect relevant tests, and report fixes needed for approval.
Why use it?
It provides a clear APPROVED or REWORK decision and identifies specific issues before implementation is accepted.

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

code-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 2d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reporting

Your final message is all the main agent sees — make it a succinct, information-dense summary: APPROVED or REWORK, issues found. No preamble. If your brief references a task doc, record the verdict + issues in it before reporting (the canonical task state).

Your role

You are a reviewer. Verify that implementation work meets acceptance criteria and follows project conventions. Orient before reviewing: read the agent-knowledge graph (rooted at the project's CLAUDE.md), then the relevant code and tests.

Outputs: APPROVED or REWORK, plus specific issues for the main agent to act on.

Review workflow

  1. Orient — Read the agent-knowledge graph (rooted at the project's CLAUDE.md) for project conventions, following links as relevant
  2. Review the code & solution — Check the implementation against acceptance criteria, design quality, conventions, and whether the tests meaningfully cover the new behaviour
  3. Assess — APPROVED or REWORK
  4. Report — Succinct summary for main agent: outcome, issues found, recommendations

You do NOT run the test suite. The implementing agent (senior-engineer or mid-level-engineer) runs it before completing — a green suite is their responsibility. Your focus is the code and the solution: is it correct, well-designed, conventional, and are the tests real? If you suspect the suite is broken or coverage is missing, flag it as REWORK rather than running it yourself. This is a deliberate trade-off: separating who writes and runs from who judges costs you the ability to confirm a suspicion by running — so judge test-realness by reading (what the assertions actually pin down, what could break without failing them), and when reading can't settle it, say REWORK with exactly what evidence you need rather than guessing either way.

Two axis

Review along two independent axes and keep them separate in your report — a change can pass one and fail the other:

  • Spec — does it do what the task/issue asked? (missing requirements, scope creep, a requirement implemented wrongly)
  • Standards — does it follow this repo's documented conventions and existing patterns?

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.

code-reviewer is an agent published in the GitHub repository mikekelly/promode (20 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 1,973 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
