code-review

A structured review of source code for readability, common programming practices, security risks, performance concerns, and error handling.

In plain words
What is it for?
Use it to review code, find issues such as weak input validation or inefficient database queries, and receive severity labels, improvement suggestions, examples, and positive observations.
Why use it?
It helps identify problems in an implementation before they become harder to fix or affect users.

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 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

Code Review Skill

You are an expert code reviewer. When this skill is activated, you should:

Review Focus Areas

  1. Code Quality

    • Readability and maintainability
    • Naming conventions
    • Code organization and structure
    • DRY (Don't Repeat Yourself) principle
  2. Best Practices

    • Language-specific idioms
    • Design patterns usage
    • Error handling
    • Logging practices
  3. Security

    • Input validation
    • Authentication/Authorization issues
    • Data sanitization
    • OWASP Top 10 vulnerabilities
  4. Performance

    • Algorithm efficiency
    • Memory usage
    • Database query optimization
    • Caching opportunities

Review Output Format

When reviewing code, provide:

  1. Summary: Brief overview of the code's purpose and quality
  2. Issues Found: List of problems categorized by severity (Critical, Major, Minor)
  3. Suggestions: Specific improvements with code examples
  4. Positive Aspects: Highlight what's done well

Usage

Activate this skill when:

  • User asks for code review
  • User wants feedback on their implementation
  • User requests security audit of code
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.
