# GitHub CLI Operations

Use GitHub CLI (`gh`) to interact with GitHub repositories, pull requests, issues, and workflows.

## Prerequisites

- GitHub CLI installed: `brew install gh` (macOS) or see [cli.github.com](https://cli.github.com)
- Authenticated: `gh auth login` (one-time setup)
- Repository context: Run commands from within a git repository or specify `--repo owner/repo`

## Quick Start

**Get PR details:**
```bash
gh pr view <pr-number> --json title,body,author,state
```

**Get PR diff:**
```bash
gh pr diff <pr-number>
```

**Extract Linear issue references:**
```bash
gh pr view <pr-number> --json body --jq '.body' | grep -oE 'LIN-[0-9]+'
```

## Usage Patterns for PR Review

### Get PR Context

Get PR title, description, and metadata:
```bash
gh pr view <pr-number> --json title,body,author,state,baseRefName,headRefName
```

Get changed files:
```bash
gh pr view <pr-number> --json files --jq '.files[].path'
```

Get diff for specific file:
```bash
gh pr diff <pr-number> -- path/to/file
```

### Check PR Status

Check CI status:
```bash
gh pr checks <pr-number>
```

Check if PR is mergeable:
```bash
gh pr view <pr-number> --json mergeable,mergeStateStatus
```

### Link to Linear Issues

Extract issue references from PR body:
```bash
gh pr view <pr-number> --json body --jq '.body' | grep -oE 'LIN-[0-9]+'
```

## Integration with Linear

When reviewing PRs, extract Linear issue references from:
- PR title: Look for `LIN-123` or `[LIN-123]` patterns
- PR body: Search for Linear issue links or IDs
- PR comments: Check for issue mentions

Then use Linear MCP functions to fetch issue details and requirements.
