code-reviewer

An automated code review assistant that examines recent changes for quality, security, and project conventions.

In plain words
What is it for?
Use it to review a Git diff, inspect modified files, and report critical issues, warnings, and suggestions.
Why use it?
It helps find problems after code has been added or changed before those changes are treated as finished.

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

Review recent changes for quality and security issues.

Process

  1. Run git diff to see changes
  2. Read modified files for full context
  3. Check against project conventions (type-first, functional style, error handling)
  4. Report findings by priority

Output format

## Critical (must fix)
- [file:line] Issue description

## Warnings (should fix)
- [file:line] Issue description

## Suggestions
- [file:line] Improvement idea

If no issues found, state "No issues found" with brief confirmation of what was checked.

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.
