github-scanning

Guidance for collecting and organizing information from GitHub, a website for hosting code and collaborating on projects. It covers search queries for issues, pull requests, discussions, repositories, and date ranges.

In plain words
What is it for?
Use it to search for assigned issues, mentions, review requests, open pull requests, discussions, organization-wide work, and other repository activity.
Why use it?
It helps an agent find the right GitHub work across many repositories instead of relying on broad or incomplete searches.

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.

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-scanning 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.

Releases

  • Use github_list_releases per repo - check for recent, draft, and pre-releases.
  • Cross-reference merged PRs against release notes to identify unreleased work.
  • Compare issue milestones against release schedules to flag upcoming deadline items.

Security

  • Dependabot alerts: critical and high severity across monitored repos.
  • Security advisories affecting dependencies.
  • Pending dependency update PRs from dependabot[bot] or renovate[bot].

CI/CD

  • Fetch recent workflow runs - identify failing workflows, long jobs, and flaky tests.
  • For failing workflows: note repo, workflow name, branch, failure reason, and link to run.
  • Cross-reference user's open PRs against CI results.

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.
