review

A code-review command that examines a change for correctness, readability, architecture, security, and performance.

In plain words
What is it for?
Use it to review staged changes or recent commits and receive findings grouped by severity with file locations and suggested fixes.
Why use it?
It provides a structured way to find bugs, weak tests, unsafe handling, poor boundaries, and inefficient operations before the change is accepted.

Made for: Claude Code.

Per session 16 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 178 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 yesterday.

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

Invoke the agent-skills:code-review-and-quality skill.

Review the current changes (staged or recent commits) across all five axes:

  1. Correctness — Does it match the spec? Edge cases handled? Tests adequate?
  2. Readability — Clear names? Straightforward logic? Well-organized?
  3. Architecture — Follows existing patterns? Clean boundaries? Right abstraction level?
  4. Security — Input validated? Secrets safe? Auth checked? (Use security-and-hardening skill)
  5. Performance — No N+1 queries? No unbounded ops? (Use performance-optimization skill)

Categorize findings as Critical, Important, or Suggestion. Output a structured review with specific file:line references and fix recommendations.

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.
