A setup and usage guide for GitHub’s command-line program, called gh. GitHub is a service for hosting code and collaborating through issues, pull requests, releases, and automated workflows.

Use it to install or verify gh, authenticate with a GitHub token, and work with issues, pull requests, releases, projects, labels, and workflow status.

It helps an agent use GitHub when the gh program is missing, authentication needs checking, or the repository uses a proxy instead of the usual GitHub address.

gh — Skill for Claude Code and Codex by open-gsd: A setup and usage guide for GitHub’s command-line program…

About the project

GSD Pi is a command-line coding agent and project workflow system that plans, implements, verifies, and tracks software work through milestones, tasks, Git worktrees, and stored project notes. It is for developers who want structured, longer-running agent sessions using different model providers. The catalogue entries extend GSD Pi with skills and agents.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/open-gsd/gsd-pi

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.

Model	Per session	Once invoked
Fable 5.1	$0.00141	$0.02253
Opus 5	$0.00071	$0.01126
Sonnet 5	$0.00028	$0.00451
Haiku 4.5	$0.00014	$0.00225

Security

Grade A, and why

gh 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 6d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/experiment_cleanup.py, scripts/github_project_setup.py, tests/__init__.py, …), 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.

GitHub CLI (gh) — Setup and Usage

Purpose

Ensures the GitHub CLI (gh) is available and provides correct usage patterns for AI agents operating in environments where gh may not be pre-installed and where git remotes point to local proxies instead of github.com.

When to Use

gh command not found or shutil.which("gh") returns None
Need to interact with GitHub API (issues, PRs, releases, workflows)
Repository remote does not point to github.com (proxy environments)
Need authenticated GitHub operations with GITHUB_TOKEN
Managing GitHub Issues, Projects V2, Milestones, or Labels

Installation

gh is assumed to be already installed via the system package manager:

macOS: brew install gh
Windows: winget install GitHub.cli
Linux (Debian/Ubuntu): apt install gh

For CI monitoring operations (watching workflow runs, checking statuses, waiting for jobs), use ci_monitor.cjs:

node src/resources/skills/github-workflows/references/gh/scripts/ci_monitor.cjs

Authentication

GITHUB_TOKEN environment variable provides automatic authentication. No manual gh auth login needed.

# Verify authentication
gh auth status

If GITHUB_TOKEN is set, gh authenticates automatically for all API calls.

Repository Detection

<repo_detection>

Git remote points to a local proxy (127.0.0.1), NOT github.com. Every gh command fails without explicit repo specification:

failed to determine base repo: none of the git remotes configured for this
repository point to a known GitHub host.

RULE: Pass -R (or --repo) on EVERY gh command:

gh <command> -R open-gsd/gsd-pi

This applies to ALL gh subcommands: pr, issue, run, api, release, project, etc.

</repo_detection>

Common Commands (v2.87.0)

<gh_commands>

Pull Requests

# List open PRs
gh pr list -R open-gsd/gsd-pi

# View PR details

# Check PR CI status

# Create PR
gh pr create -R open-gsd/gsd-pi --title "title" --body "body"

# View PR comments

Files

What ships with it

8 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.

Changes

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.

gh is a skill published in the GitHub repository open-gsd/gsd-pi (1,201 stars, last pushed today), licensed MIT. It adds 141 tokens to every session and 2,253 once invoked, about $0.0007 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 2026-08-30.
