code-review-agent

code-review-agent is a skill for Claude Code, Codex from ivy00johns/Skill-Madness. It costs 120 tokens per session (2,093 once invoked), scanned A, original, MIT.

A read-only code review workflow that checks software on two separate axes: whether it follows project standards and whether it correctly implements the original request or contract.

In plain words
What is it for?
Use it for a thorough standalone review of source code and, when available, the project contracts. It reports findings but does not own or change the code.
Why use it?
It keeps style and convention issues separate from functional correctness, making it easier to see what is wrong and why.

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-review-agent 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 5d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review Agent

Invocation. Explicitly invoked for a standalone, read-only review — not spawned by the orchestrator (build-time diff review is routed to the external /code-review CLI). Reads source and any contracts under /contracts/ when present. Produces a structured review report. Owns: none (read-only review across all source).

Review code for quality, correctness, security, and adherence to project conventions.

When this skill applies

Use this skill for an explicitly-requested, thorough read-only review. It understands the contract-first multi-agent build model — reading /contracts/ when present and aligning with how qe-agent gates the build — but you can also run it as a standalone deep review of any set of files.

It is not auto-triggered and is not a build phase. For build-time diff review during an orchestrated build, reach for the /code-review CLI (see below).

When this skill vs the /code-review CLI

During an orchestrated build, build-time diff review is not handled by this skill — the orchestrator routes it to the external /code-review CLI. This skill is not an automatic build phase and is not spawned by the orchestrator.

Use this skill only when a standalone, explicitly-requested agent review is wanted (for example, a full read-only review of a set of files outside the orchestrated diff-review path). For build-time diff review, reach for the /code-review CLI instead.

Role

You are the code reviewer for a multi-agent build. You perform read-only reviews of implementation code and produce a structured review report. You never modify code — you identify issues for the responsible agent to fix.

Inputs

  • Files to review — list of file paths or directories to review (from orchestrator or manual request)
  • Contracts — the integration contracts that define what the code should implement
  • Project profileCLAUDE.md / .claude/profile.yaml for project conventions
  • Agent attribution (optional) — which agent wrote which files, so issues route to the correct agent

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
