review

A skill for reviewing code changes, pull requests, or selected files. It checks correctness, security, code quality, performance, and error handling.

In plain words
What is it for?
Use it to review uncommitted or staged changes, recent commits, pull-request diffs, or specific files, with findings grouped by severity.
Why use it?
It helps find bugs, unsafe input handling, hardcoded secrets, duplication, and inefficient code before changes are 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

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 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.

What it actually says

Review - Code Review

Comprehensive code review for changes, PRs, or specific files. You do the work directly.

Step 1: Identify Scope

AskUserQuestion:
  questions:
    - question: "What would you like to review?"
      header: "Scope"
      multiSelect: false
      options:
        - label: "Uncommitted changes"
          description: "Review git diff"
        - label: "Staged changes"
          description: "Review git diff --cached"
        - label: "Recent commits"
          description: "Review last few commits"
        - label: "Specific files"
          description: "I'll specify paths"

Step 2: Gather Code

git diff                    # Uncommitted
git diff --cached           # Staged
git log -p -n 3            # Recent commits
gh pr diff [number]        # PR

Step 3: Review

Check these areas directly:

Correctness

  • Logic errors, edge cases, error handling

Security

  • Input validation, no hardcoded secrets, injection risks

Quality

  • Clear naming, no duplication, appropriate comments

Performance

  • No N+1 queries, proper resource handling

Step 4: Report

Present findings by severity:

## Code Review

### Critical (Must Fix)
- [Issue]: [Location] - [Problem and fix]

### High Priority
- [Issue]: [Location] - [Problem and fix]

### Suggestions
- [Minor improvements]

### Positive
- [Good patterns observed]

Step 5: Next Steps

AskUserQuestion:
  questions:
    - question: "Review complete. How proceed?"
      header: "Action"
      multiSelect: false
      options:
        - label: "Fix critical"
          description: "Address blockers only"
        - label: "Fix all"
          description: "Apply all suggested fixes"
        - label: "Accept as-is"
          description: "Proceed without changes"

If fixing, make the changes directly using Edit tool.

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.

review is a skill published in the GitHub repository Zate/cc-plugins (10 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 523 once invoked, about $0.0001 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 2026-08-31.
