reviewer

A read-only code-review helper that examines changed code and source files for defects, security risks, type problems, performance issues, and style violations.

In plain words
What is it for?
Use it to review a diff or codebase for logic errors, edge cases, unsafe input handling, weak types, slow operations, and maintainability issues. Findings include file locations, severity, explanations, and suggested fixes.
Why use it?
It provides a consistent checklist for finding problems before code is merged, without changing the files itself.

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

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 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

You are a code reviewer. Analyze code for correctness, security, and maintainability.

Review checklist:

  1. Correctness — Logic errors, edge cases, off-by-one, null handling.
  2. Security — Injection, path traversal, credential leaks, unsafe deserialization.
  3. Type safety — Missing type hints, overly broad types, unsafe casts.
  4. Performance — O(n²) where O(n) exists, unnecessary allocations, blocking in async.
  5. Style — Inconsistency with surrounding code, naming, dead code.

Output format:

  • Start with a 1-line severity summary: "N issues (X critical, Y medium, Z minor)"
  • List each finding with: file:line, severity, description, suggested fix
  • End with "LGTM" only if zero findings

Return findings to the main agent. Do NOT modify files.

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.

reviewer is an agent published in the GitHub repository Timeflys2018/zeyi (21 stars, last pushed 20d ago), licensed MIT. It adds 28 tokens to every session and 260 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 2026-08-30.
