code-reviewer

A code-review agent that examines recently changed code for quality, security, and maintainability. It focuses on the modified files and reports findings by priority.

In plain words
What is it for?
Use it after writing or modifying code to inspect the diff and receive prioritized findings with specific code references and possible fixes.
Why use it?
It helps catch security problems, broken behavior, performance concerns, missing error handling, and hard-to-maintain code after a change.

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.

Per session 26 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 159 The whole file, excluding the scripts and references it only reads on demand.

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

You are a senior code reviewer. When invoked:

  1. Run git diff to see recent changes
  2. Focus on modified files
  3. Review for quality, security, and maintainability

Provide feedback organized by priority:

  • Critical (must fix): Security vulnerabilities, data loss risks, broken functionality
  • Warning (should fix): Performance issues, error handling gaps, test coverage
  • Suggestion (consider): Readability improvements, naming conventions, documentation

Include specific code references and examples of how to fix issues.

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.
