github

A tool for using GitHub's REST and GraphQL APIs, which let software inspect and change repositories, issues, pull requests, users, and comments.

In plain words
What is it for?
Use it to find repositories, read their descriptions and READMEs, inspect issues and pull requests, view user profiles, create issues or comments, and manage stars.
Why use it?
It avoids manually navigating GitHub when researching code or carrying out routine repository-management tasks.

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 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.

The scan reads SKILL.md. This mod also ships 2 executable files (adapters/github-read.ts, adapters/github-web.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Overview

GitHub REST + GraphQL API — code hosting platform (developer tools archetype).

Workflows

Explore a repository

  1. searchRepos(q) → pick result → owner, repo from full_name
  2. getRepo(owner, repo) → description, stars, language
  3. getRepoReadme(owner, repo) → base64-encoded README content
  4. listIssues(owner, repo) → open issues
  5. listPullRequests(owner, repo) → open PRs

Investigate a user's work

  1. getUserProfile(username) → bio, public_repos, followers
  2. searchRepos(q: "user:username") → their repositories

File an issue

  1. searchRepos(q)owner, repo from full_name (or use known repo)
  2. createIssue(owner, repo, title, body)number, html_url

Manage issues

  1. listIssues(owner, repo)issue_number, title, state
  2. closeIssue(owner, repo, issue_number ← listIssues)state: "closed"
  3. reopenIssue(owner, repo, issue_number ← listIssues)state: "open"
  4. createComment(owner, repo, issue_number ← listIssues, body)comment_id, html_url
  5. deleteComment(owner, repo, comment_id ← createComment) → 204

Star / watch a repo

  1. searchRepos(q)owner, repo from full_name
  2. starRepo(owner, repo) → 204
  3. unstarRepo(owner, repo) → 204
  4. watchRepo(owner, repo)subscribed
  5. unwatchRepo(owner, repo) → 204

Operations

Operation Intent Key Input Key Output Notes
searchRepos find repositories q total_count, items[].full_name, stargazers_count, language entry point, paginated

listPullRequests repository PRs owner ← getRepo, repo ← getRepo number, title, state, user.login, head.ref, base.ref paginated
listContributors repository contributors owner ← getRepo, repo ← getRepo login, contributions paginated
createIssue create an issue owner ← getRepo, repo ← getRepo, title, body number, html_url write, CAUTION
closeIssue close an issue owner, repo, issue_number ← listIssues data (GraphQL response) write, CAUTION. Routes through github.com /_graphql
reopenIssue reopen a closed issue owner, repo, issue_number ← listIssues data (GraphQL response) write, CAUTION — reverse of closeIssue. Routes through github.com /_graphql
createComment comment on issue/PR owner, repo, issue_number ← listIssues, body id, body, html_url write, CAUTION
deleteComment delete a comment owner, repo, comment_id ← createComment — (204) write, CAUTION — reverse of createComment
forkRepo fork a repository owner ← getRepo, repo ← getRepo full_name write, CAUTION
starRepo star a repository owner ← getRepo, repo ← getRepo — (204) write, SAFE. (api.github.com — currently rejected by cookie_session, see DOC.md)
unstarRepo unstar a repository owner ← getRepo, repo ← getRepo count (watcher count) write, CAUTION — reverse of starRepo. Routes through github.com rails endpoint
watchRepo watch a repository owner ← getRepo, repo ← getRepo count (watcher count) write, CAUTION. Routes through github.com /notifications/subscribe
unwatchRepo unwatch a repository owner ← getRepo, repo ← getRepo count (watcher count) write, CAUTION — reverse of watchRepo. Routes through github.com /notifications/subscribe
graphqlQuery execute GraphQL query, variables data write (unrestricted mutations possible)

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.

github is a skill published in the GitHub repository imoonkey/openweb (56 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,549 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
