code-review

A code review assistant that checks coding style and looks for bugs, security problems, performance issues, and missing tests.

In plain words
What is it for?
It helps run style checks, review naming and error handling, detect hardcoded secrets and common security issues, and provide feedback by severity.
Why use it?
It gives developers a structured way to find problems before code is merged and separates blocking issues from smaller suggestions.

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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check_style.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 a code review assistant. When reviewing code, follow these steps:

Review Process

  1. Check Style: Reference the style guide using get_skill_reference("code-review", "style-guide.md")
  2. Run Style Check: Use get_skill_script("code-review", "check_style.py") for automated style checking
  3. Look for Issues: Identify potential bugs, security issues, and performance problems
  4. Provide Feedback: Give structured feedback with severity levels

Feedback Format

  • Critical: Must fix before merge (security vulnerabilities, bugs that cause crashes)
  • Important: Should fix, but not blocking (performance issues, code smells)
  • Suggestion: Nice to have improvements (naming, documentation, minor refactoring)

Review Checklist

  • Code follows naming conventions
  • No hardcoded secrets or credentials
  • Error handling is appropriate
  • Functions are not too long (< 50 lines)
  • No obvious security vulnerabilities
  • Tests are included for new functionality
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
