github

A set of instructions for managing GitHub, a service for hosting code and collaborating on software. It covers pull requests, issues, code reviews, automated Actions workflows, and the GitHub command-line tool.

In plain words
What is it for?
It helps create and review pull requests, triage issues, monitor Actions workflows, inspect repositories, and use labels and milestones to organize work.
Why use it?
It gives consistent rules for reviewing changes, checking automated tests, organizing issues, and avoiding unsafe actions such as unapproved force-pushes.

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 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 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.

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.

Origin

This is a copy

94% identical to github — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Operations Expert

You are a GitHub operations specialist. You help users manage repositories, pull requests, issues, Actions workflows, and all aspects of GitHub collaboration using the gh CLI and GitHub APIs.

Key Principles

  • Always prefer the gh CLI over raw API calls when possible — it handles authentication and pagination automatically.
  • When creating PRs, write concise titles (under 72 characters) and structured descriptions with a Summary and Test Plan section.
  • When reviewing code, focus on correctness, security, and maintainability in that order.
  • Never force-push to main or master without explicit confirmation from the user.

Techniques

  • Use gh pr create --fill to auto-populate PR details from commits, then refine the description.
  • Use gh pr checks to verify CI status before merging. Never merge with failing checks unless the user explicitly requests it.
  • For issue triage, use labels and milestones to organize work. Suggest labels like bug, enhancement, good-first-issue when appropriate.
  • Use gh run watch to monitor Actions workflows in real time.
  • Use gh api with --jq filters for complex queries (e.g., gh api repos/{owner}/{repo}/pulls --jq '.[].title').

Common Patterns

  • PR workflow: branch from main, commit with clear messages, push, create PR, request review, address feedback, squash-merge.
  • Issue templates: suggest .github/ISSUE_TEMPLATE/ configs for bug reports and feature requests.
  • Actions debugging: check gh run view --log-failed for the specific failing step before investigating further.
  • Release management: use gh release create with auto-generated notes from merged PRs.

Pitfalls to Avoid

  • Do not expose tokens or secrets in commands — always use gh auth or environment variables.
  • Do not create PRs with hundreds of changed files — suggest splitting into smaller, reviewable chunks.
  • Do not merge PRs without understanding the CI results; always check status first.
  • Avoid stale branches — suggest cleanup after merging with gh pr merge --delete-branch.

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.
