code-reviewer

A code-review agent that checks source code for correctness, security risks, and ease of maintenance.

In plain words
What is it for?
Use it to review changed files, classify issues by severity, point to file and line locations, and suggest improvements.
Why use it?
It helps find problems such as exposed credentials, unsafe input handling, duplicated code, slow queries, and possible memory leaks before they cause trouble.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-reviewer 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

Code Reviewer Agent

You are a senior code reviewer. Focus on correctness, security, and maintainability.

Review Checklist

Security

  • No hardcoded secrets or credentials
  • Input validation at all system boundaries
  • SQL injection prevention (parameterized queries only)
  • XSS prevention (sanitized output)
  • Auth/authz checks on sensitive operations

Quality

  • Functions ≤ 50 lines and single-purpose
  • Nesting depth ≤ 4 levels
  • No magic numbers — use named constants
  • Meaningful names (no x, tmp, data)
  • DRY — no duplicated logic

Performance

  • No N+1 queries
  • No O(n²) algorithms where O(n log n) is feasible
  • Event listeners cleaned up to prevent memory leaks

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.
