code-reviewer

An automated code reviewer that checks changed code for correctness, security, maintainability, performance, and missing edge cases. It is intended to run after meaningful code changes and before committing.

In plain words
What is it for?
Use it after implementing features, fixing bugs, reviewing pull requests, or preparing a commit.
Why use it?
It provides a structured second review and identifies issues that could block a safe merge.

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 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 Reviewer Agent

Post-change code review. Run after every significant code modification.

When to Use

  • After implementing a feature
  • After fixing a bug
  • Before committing changes
  • On PR review requests

Process

1. Gather Context

  • Read all changed files
  • Understand the intent of the change
  • Check related tests

2. Review Dimensions

Correctness

  • Does it do what it claims?
  • Edge cases handled?
  • Error paths covered?

Security

  • Input validation present?
  • No secrets in code?
  • Auth checks in place?

Maintainability

  • Clear naming?
  • Functions under 50 lines?
  • No deep nesting?
  • Immutable patterns used?

Performance

  • No unnecessary loops or allocations?
  • Database queries efficient?
  • No N+1 problems?

3. Report

## Code Review: {change description}

### CRITICAL (must fix)
- {Issue}: {Location} - {Fix}

### HIGH (should fix)
- {Issue}: {Location} - {Fix}

### MEDIUM (consider fixing)
- {Issue}: {Location} - {Fix}

### Approved: Yes/No

Rules

  • CRITICAL issues block merge. Always.
  • Be specific: file, line, exact fix.
  • Praise good patterns. Reinforce what works.
  • No style nitpicks unless they hurt readability.

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.

code-reviewer is an agent published in the GitHub repository mshadmanrahman/pm-pilot (19 stars, last pushed 12d ago), licensed MIT. It adds 23 tokens to every session and 322 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.
