A command that checks your current code changes against the review rules written for the project.

In plain words
What is it for?
Use it to inspect the working and staged changes, mark each rule as passed, failed, or not relevant, and suggest fixes with file and line references.
Why use it?
It gives a structured review without changing files, so you can find rule violations before sharing the changes.

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

review-rules 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 4d 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

Run a rule-by-rule review of the current working tree against the tracked agent guidance and review standards.

Do this:

  1. Read AGENTS.md, the applicable scoped AGENTS.md files, and REVIEW_RULES.md.
  2. Gather the diff:
    • git diff HEAD
    • git diff --cached
    • git status --short
  3. For each relevant standard, produce:
    • Rule name: pass | fail | n/a
    • If fail: cite the specific file:line, quote the offending code, and suggest the concrete fix.
    • If n/a: one short sentence on why it does not apply to this diff.
  4. End with a Summary listing only failing rules, ordered by severity: structural/design issues first, then mechanical issues.

Do not modify files during the review. Output only.

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.
