What is github-code-review?

A GitHub pull-request review system that coordinates specialized checks for areas such as security, performance, architecture, style, and accessibility.

Use it to inspect pull-request files and diffs, run focused reviews, coordinate review agents, and post review status or findings.

It helps review a change from several perspectives instead of relying on one general pass or checking each concern separately.

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

Security

Grade A, and why

github-code-review scanned grade A with 1 finding 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 1mo 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.
