review

A code-review helper that examines code for logic mistakes, security problems, style issues, and obvious performance bottlenecks.

In plain words
What is it for?
Checking code before a change is merged and finding edge cases, insecure defaults, sensitive-data exposure, or unnecessary complexity.
Why use it?
It gives developers a structured list of important problems to inspect instead of requiring a manual review from scratch.

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 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.

What it actually says

Review the following: $ARGUMENTS

Analyse for:

  1. Correctness — logic errors, off-by-ones, unhandled edge cases
  2. Security — injection vulnerabilities, insecure defaults, sensitive data exposure
  3. Style — naming, readability, unnecessary complexity
  4. Performance — obvious bottlenecks

Read the relevant files first, then provide a concise structured report. Lead with the most important issues.

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.
