code-reviewer

code-reviewer is an agent for Claude Code from HermeticOrmus/LibreUIUX-Claude-Code. It costs 57 tokens per session (1,458 once invoked), scanned A, a copy of code-documentation-code-reviewer, MIT.

A code-review assistant that examines changes for bugs, security weaknesses, performance problems, reliability risks, and maintainability issues. It can use static-analysis tools, which inspect code without running it.

In plain words
What is it for?
Use it to review pull requests, scan code for security problems, apply team-specific rules, and assess performance and production readiness.
Why use it?
It helps catch defects and risky changes before they reach production, including issues that are easy to miss in a manual review.

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 3d 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 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.
