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.

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 |
|---|---|---|
| Fable 5 | $0.00175 | $0.01717 |
| Opus 5 | $0.00088 | $0.00859 |
| Sonnet 5 | $0.00035 | $0.00343 |
| Haiku 4.5 | $0.00017 | $0.00172 |
Grade A, and why
github-integration 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.
How it starts
The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Integration
Enable gh CLI access in Claude Code cloud and GitHub Copilot coding agent environments so agents can create PRs, manage issues, and interact with GitHub APIs.
When to Use This Skill
Activate when:
- User wants cloud AI agents to use
gh(PRs, issues, releases, API calls) - User needs to install
ghin Claude Code cloud sessions - User wants to add
copilot-setup-steps.ymlfor GitHub Copilot agents ghcommands fail with auth or "not found" errors in a cloud session- User wants to enable GitHub integration for any cloud-based AI coding agent
Decision Tree
Which cloud environment?
Claude Code cloud (claude.ai/code)?
→ gh is NOT pre-installed in the default image
→ Install via setup script: apt update && apt install -y gh
→ Set GH_TOKEN as environment variable in environment settings
→ For repo-portable setup, use SessionStart hook instead
→ Use -R owner/repo flag with gh due to sandbox proxy
GitHub Copilot coding agent?
→ Add .github/copilot-setup-steps.yml to the repo
→ gh IS pre-installed; just configure GH_TOKEN
→ Commit and push — agent sessions pick it up automatically
gh commands failing?
→ "command not found" → gh not installed; add to setup script
→ HTTP 401 → GH_TOKEN not set; add to environment variables
→ HTTP 403 → Token lacks required scope; check permissions
→ "could not determine repo" → Use -R owner/repo flag
→ See references/cloud-auth.md for more
Need gh in local dev too?
→ Run: gh auth login (interactive, browser-based)
→ Or set GH_TOKEN env var for headless/CI use
Two Environments, Two Approaches
Claude Code Cloud (claude.ai/code)
Claude Code cloud runs sessions in Anthropic-managed VMs. The gh CLI is not pre-installed. You need two things:
- Setup script — installs
ghwhen the session starts GH_TOKENenv var — authenticatesghwith your GitHub PAT
Quick Start: Setup Script
In the Claude Code web UI: Environment Settings → Setup script:
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-integration is a skill published in the GitHub repository onsager-ai/dev-skills (5 stars, last pushed 20d ago), licensed MIT. It adds 175 tokens to every session and 1,717 once invoked, about $0.0009 per session on Opus 5. 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 2026-08-31.
