# 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

If `gh` is not installed, run the setup script:

```bash
uv run .claude/skills/gh/scripts/setup_gh.py
```

The script:

1. Checks if `gh` is already installed via `shutil.which`
2. Detects platform (Linux, macOS, Windows) and architecture
3. Fetches the latest release from `https://github.com/cli/cli/releases/latest`
4. Downloads the correct archive with SHA256 verification from checksums file
5. Extracts and installs the binary to a writable PATH directory
6. Uses `GITHUB_TOKEN` for authenticated requests; falls back to anonymous if auth fails (401/403)

**CLI options:**

```text
--force          Reinstall even if already at latest version
--dry-run        Show what would happen without installing
--bin-dir        Override install directory (default: auto-detect from PATH)
--detect-only    Detect owner/repo, refresh .dh/config.yaml and gh-examples.md, print examples to stdout. No network calls.
```

---

## Authentication

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

```bash
# 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:

```text
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:**

```bash
gh <command> -R <owner/repo>
```

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

</repo_detection>

## Common Commands

!`uv run --script .claude/skills/gh/scripts/setup_gh.py --detect-only 2>/dev/null`

---

## Automation — Python Script

For multi-step operations (label setup, milestone creation, project init, issue import), use:

```bash
# Full project setup
uv run .claude/skills/gh/scripts/github_project_setup.py setup

# Labels only
uv run .claude/skills/gh/scripts/github_project_setup.py labels

# Milestone management
uv run .claude/skills/gh/scripts/github_project_setup.py milestone list
uv run .claude/skills/gh/scripts/github_project_setup.py milestone create --title "v1.0" --due 2026-03-31

# Issue management
uv run .claude/skills/gh/scripts/github_project_setup.py issue list --priority p1
uv run .claude/skills/gh/scripts/github_project_setup.py issue create --title "feat: X" --priority-label priority:p1
```

The script delegates all GitHub operations to the authenticated `gh` CLI — no separate API tokens or Python HTTP clients needed.
