github

An autonomous security-testing agent for GitHub and GitHub Enterprise, the services used to host code and manage software teams.

In plain words
What is it for?
Use it to test GitHub accounts and projects for security weaknesses, including risks in automated Actions workflows and stored secrets.
Why use it?
It examines GitHub organisations, repositories, access tokens, apps, workflows, secrets, runners, packages, and branch rules in one security review.

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 49 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 5,875 The whole file, excluding the scripts and references it only reads on demand.

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

github 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 yesterday.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
