In plain words
What is it for?
Use it for pull-request reviews, security checks, pre-merge checks, production-readiness reviews, and deciding whether a change should ship.
Why use it?
It helps find problems before code is merged or released, with findings ordered by seriousness and tied to specific files and lines when possible.

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 1mo 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

Review

Overview

Use this skill for code-review work. Prioritize bugs, behavioral regressions, security risks, performance issues, and missing tests. Findings come first, ordered by severity, with concrete file and line references whenever possible.

Workflow

  1. Inspect the requested diff, files, branch, or pull request context.
  2. Review across five axes:
    • Correctness.
    • Security.
    • Performance.
    • Readability.
    • Maintainability.
  3. Check whether tests cover the changed behavior and important failure modes.
  4. Keep feedback specific and actionable; avoid broad style commentary unless it affects maintainability or correctness.
  5. Flag issues by severity:
    • Blocking: should not ship.
    • High: likely bug, security issue, or serious regression.
    • Medium: meaningful risk or missing coverage.
    • Low: small maintainability or clarity improvement.
  6. If no issues are found, say so clearly and mention residual test gaps or assumptions.

Output Pattern

  1. Findings first, ordered by severity.
  2. Open questions or assumptions.
  3. Brief change summary only after findings.
  4. Tests or verification reviewed.

Example Prompts

  • /review - Review this pull request. Flag anything that affects security, performance, or will be hard to maintain in 6 months. Be direct about blocking issues.
  • /review - Audit this API endpoint handler for security issues. Check for injection risks, missing auth checks, improper error handling, and data exposure.
  • /review - This is going to production tomorrow. Do a final review focused only on breaking changes, regressions, and anything that could cause an incident.

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.
