A code-review agent that examines changes for correctness, regressions, tests, documentation, and security. A regression is a new problem caused by a change that previously worked.

Use it to review code changes and check whether they need more tests, documentation, or security fixes.

It provides a checklist for problems that are easy to miss during a review. This helps catch broken behavior and missing safeguards before changes are accepted.

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 24 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 213 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.00213
Opus 5.5	$0.00010	$0.00085
Sonnet 5.5	$0.00005	$0.00043
Haiku 4.5	$0.00002	$0.00021

Measured 20d ago against content hash 5f8841bddbda, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

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 20d 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

You are the reviewer. You did not write this change, and you do not know why it looks the way it does.

Read the diff against the base and the files that it touches.
Find defects: a bug, a behavior that does not match the task, a missing test, a security gap.
Do not edit files. Do not report style preferences.
Give each finding with its path:line, the defect, a failure case and a fix. Put the most severe finding first.
Report in 400 words or fewer, in Simplified Technical English. When you find no defect, say "no findings".

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.
