description This skill should be used when working with GitHub CLI (gh) for pull requests, issues, releases, and GitHub automation. Use when users mention gh commands, GitHub workflows, PR operations, issue management, or GitHub API access. Essential for understanding gh's mental model, command structure, and integration with git workflows.

GitHub CLI (gh)

Overview

GitHub CLI (gh) is the official command-line tool for GitHub that brings pull requests, issues, releases, and other GitHub concepts to the terminal. This skill provides comprehensive guidance for using gh to streamline GitHub workflows, including PR management, issue tracking, repository operations, and API access.

When to Use This Skill

Invoke this skill when users:

  • Mention GitHub CLI (gh) commands or workflows
  • Ask about creating, viewing, or managing pull requests from the command line
  • Need help with GitHub issue management via CLI
  • Want to understand gh's mental model or command structure
  • Request guidance on GitHub automation or scripting
  • Ask about GitHub API access through gh
  • Need help with gh authentication or configuration
  • Request integration patterns between gh, git, and other tools (like workstack)

Core Concepts

Before providing guidance, understand these key concepts:

Three-Layer Architecture:

  1. High-Level Commands (porcelain): gh pr, gh issue, gh repo - user-friendly workflows
  2. API Access: gh api - direct REST/GraphQL access with built-in auth
  3. Git Integration: Smart repo detection from git remotes and current branch

Context Resolution:

  • gh automatically detects repository from git remotes
  • Uses current branch to infer PR context
  • Falls back to interactive selection when ambiguous

Mental Model: Think of gh as "GitHub workflows made CLI-native" - each command maps to a common GitHub workflow optimized for terminal use.

Using the Reference Documentation

When providing gh guidance, load the comprehensive reference documentation:

references/gh.md

This reference contains:

  • Complete mental model and terminology
  • Full command reference for PRs, issues, repos, releases, and more
  • Authentication and configuration patterns
  • Workflow patterns for common scenarios
  • Integration details (workstack, git, CI/CD)
  • GitHub API access patterns
  • Practical examples for daily development

Loading Strategy:

  • Always load references/gh.md when user asks gh-related questions
  • The reference is comprehensive (~1480 lines) but optimized for progressive reading
  • Use grep patterns to find specific sections when needed:
    • gh pr - Pull request commands
    • gh issue - Issue management commands
    • gh repo - Repository operations
    • gh api - API access patterns
    • Pattern [0-9]: - Workflow patterns
    • Authentication - Auth setup
    • workstack Integration - Integration with workstack

Common Operations

When users ask for help with gh, guide them using these patterns:

First-Time Setup

  1. Check if gh is installed: gh --version
  2. Authenticate: gh auth login (interactive) or gh auth status (check current)
  3. Configure defaults: gh config set <key> <value>
  4. Test connection: gh repo view (in a git repo)

Pull Request Operations

Load references/gh.md and search for "gh pr" section to provide:

  • Creating PRs: gh pr create (interactive or with flags)

GraphQL API Reference

When standard gh commands are insufficient, use GraphQL via gh api graphql. Load references/graphql.md for comprehensive GraphQL guidance.

When to Use GraphQL:

Use GraphQL when the porcelain commands (gh pr, gh issue, etc.) cannot accomplish the task:

  • Projects V2: No REST API exists - all operations require GraphQL

    • Create/update projects
    • Add items and update field values
    • Query custom fields and project data

  • Discussions: No porcelain commands available

    • Create/manage discussions
    • Add comments and replies
    • Query discussion categories

  • Batch Operations: Query multiple resources in one API call

    • Compare multiple repositories
    • Aggregate data across repos
    • Reduce rate limit consumption

  • Complex Queries: Fetch nested data efficiently

    • PR with reviews, comments, and status checks in one call
    • Issue with timeline, reactions, and linked PRs
    • Repository with open issues, PRs, and contributors

  • Advanced Search: Complex filtering beyond basic commands

    • Multi-criteria issue/PR searches
    • Boolean logic and date ranges
    • Advanced sorting options

  • Custom Fields: Precise field selection

    • Request only needed fields
    • Optimize for performance
    • Build custom data aggregations

GraphQL Resources:

  • references/graphql.md - Complete GraphQL guide including:

    • Use cases requiring GraphQL
    • Common patterns (variables, pagination, batching, etc.)
    • Complete examples (Projects V2, Discussions, batch queries)
    • Best practices and troubleshooting

  • references/graphql-schema-core.md - Core schema types (load only when needed):

    • Detailed field information for Repository, Issue, PullRequest, etc.
    • Projects V2 field types and mutations
    • Discussion types and operations
    • Input types and enums

Loading Strategy:

  1. Start with references/graphql.md for use cases and patterns
  2. Load references/graphql-schema-core.md only when detailed schema info is needed
  3. Use grep patterns to find specific sections:
    • Projects V2 - Project automation examples
    • Discussion - Discussion API examples
    • Batch - Batch query patterns
    • Pagination - Cursor-based pagination
    • Example [0-9] - Complete working examples

Troubleshooting

When users encounter issues:

  1. Check authentication: gh auth status
  2. Verify repository detection: gh repo view
  3. Test API access: gh api user
  4. Review configuration: gh config list
  5. Check rate limits: gh api rate_limit
  6. Enable debug mode: GH_DEBUG=api gh <command>

Load the Troubleshooting section from references/gh.md for specific error patterns.

Command Discovery

When users ask "what can gh do?":

  • Start with overview of main commands: pr, issue, repo, release, workflow
  • Show command help: gh <command> --help
  • Demonstrate interactive mode: most commands work interactively
  • Point to gh api for anything not covered by porcelain commands
  • Reference the full command reference in references/gh.md
