code-review

code-review is a skill for Claude Code, Codex from raghatatepiyush/ringmaster. It costs 173 tokens per session (1,932 once invoked), scanned A, original, MIT.

A read-only code-review skill that checks a change against both its requirements and software-quality standards. A pull request is a proposed code change for review before it is merged.

In plain words
What is it for?
Use it to review a change, branch, or pull request for correctness, safety, project fit, and compliance with the requested behavior.
Why use it?
It prevents reviewers from focusing only on code style while missing a requirement, or accepting messy code simply because it appears to meet the ticket.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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 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 3d 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

Ringmaster's detection layer asks two questions of every change, and they are genuinely different:

Spec — did we build the right thing? Does the change do what was asked — the plan, the PRD, the ticket — no more and no less?

Standards — did we build the thing right? Is the code correct, safe on its edges, and does it look like it belongs in this repo?

A single reviewer holding both questions at once bleeds them together — excusing messy code because "it matches the ticket", or polishing style while a whole requirement is quietly missing. So this skill runs the two axes as parallel fresh-context sub-agents (agents/code-reviewer.md, dispatched twice — once per axis) and lays their two reports side by side. Separation is the point.

This skill is stack-independent. It reviews; it does not fix, and it does not re-run the Security Gate — it stands beside it.


The safety rails (inherited, non-negotiable)

The same rails the orchestrator enforces (hook-backed, hold under skip-permissions):

  1. You review; you never fix. Read-only. A real defect goes into the record and back to the human — you don't patch it.
  2. You never commit, push, or write history. The only thing this skill writes is the ledger's gate.clean record. The human commits and ships.
  3. Never run anything against production. Running the change's own tests to confirm a claim is DEV/UAT only.
  4. Never rubber-stamp. ✅ clean is a valid verdict only when the paths were actually traced. Manufacturing findings to look thorough is as dishonest as waving a broken change through.

Where this sits in "code review with Ringmaster"

Security Gate  →  code-review  →  Ownership Review  →  sign-off
  (secrets,       (Spec: right       (reconstruct         (gate.owned)
   injection,      thing? +           understanding,
   authz)          Standards:         teach the holes)
                   built right?)

Detection runs in order: the Security Gate clears the diff of vulnerabilities first (it can block), then this skill reviews quality and spec-fit, then the Ownership Review makes sure the human actually understands what they're about to own. This skill produces the clean verdict the ownership review assumes has already run.

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.
