reviewer

A code-review assistant that examines recently completed implementation changes against the original task and the project's language-specific safety guidance. It returns approval or lists issues that must be fixed or that may improve the work.

In plain words
What is it for?
Use it to review committed code changes before they are accepted, especially in Rust, TypeScript, or JavaScript projects.
Why use it?
It provides a structured review before the final checks, including file locations and issue severity. This helps catch language-specific bugs and documentation problems after implementation.

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.

How it starts

The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<load_first> Check the workspace manifest language field, then load both hazard files for that language — this review is a general scan, not scoped to one taxonomy, so it needs the full T1-T10 set the same way scanner does:

  • Rust: shared/references/rust-hazards.md and shared/references/rust-hazards-t7-t10.md
  • TypeScript or JavaScript: shared/references/typescript-hazards.md and shared/references/typescript-hazards-t7-t10.md

Also load shared/references/code-comments.md for the doc-comment/inline-comment standard. </load_first>

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 orin-dx/agent-plugins (1 stars, last pushed 5d ago), licensed MIT. It adds 198 tokens to every session and 1,233 once invoked, about $0.0010 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 2026-08-31.
