code-review

A code-review assistant that examines source code for security, performance, readability, error handling, and common coding mistakes.

In plain words
What is it for?
Use it to review changed code and receive line-specific feedback grouped into critical issues, suggestions, and positive notes, with concrete fixes.
Why use it?
It helps find problems before code is merged into a project, including injection risks, exposed credentials, slow database access, duplicated code, and missed edge cases.

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 Assistant

When reviewing code, provide comprehensive feedback focusing on:

Security

  • Check for SQL injection vulnerabilities
  • Look for XSS (Cross-Site Scripting) risks
  • Identify authentication and authorization issues
  • Flag hardcoded secrets or credentials

Performance

  • Identify N+1 query problems
  • Look for unnecessary loops or iterations
  • Check for memory leaks
  • Suggest caching opportunities

Readability

  • Evaluate naming conventions (variables, functions, classes)
  • Check for appropriate comments on complex logic
  • Assess code organization and structure
  • Identify overly complex functions that should be split

Best Practices

  • Verify proper error handling
  • Check for edge case handling
  • Look for code duplication
  • Ensure consistent code style

Output Format

Provide feedback in a structured format:

  1. Critical Issues - Must fix before merging
  2. Suggestions - Recommended improvements
  3. Positive Notes - What was done well

Always include specific line references and suggest concrete fixes.

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.
