GitHub CLI (gh)

Overview

Expert guidance for GitHub CLI (gh) operations and workflows. Use this skill for command-line GitHub operations including pull request management, issue tracking, repository operations, workflow automation, and codespace management.

Key capabilities:

• Create and manage pull requests from the terminal
• Track and organize issues efficiently
• Search across all of GitHub (repos, issues, PRs)
• Manage labels and project organization
• Trigger and monitor GitHub Actions workflows
• Work with codespaces
• Automate repository operations and releases
• Browse repositories, PRs, and files in the browser

Safety Rules

CRITICAL: This skill NEVER uses destructive gh CLI operations.

This skill focuses exclusively on safe, read-only, or reversible GitHub operations. The following commands are PROHIBITED and must NEVER be used:

Permanently destructive commands:

• gh repo delete - Repository deletion
• gh repo archive - Repository archival
• gh release delete - Release deletion
• gh release delete-asset - Asset deletion
• gh run delete - Workflow run deletion
• gh cache delete - Cache deletion
• gh secret delete - Secret deletion
• gh variable delete - Variable deletion
• gh label delete - Label deletion
• gh ssh-key delete - SSH key deletion (can lock out users)
• gh gpg-key delete - GPG key deletion
• gh codespace delete - Codespace deletion
• gh extension remove - Extension removal
• gh gist delete - Gist deletion
• Bulk deletion operations using xargs with any destructive commands
• Shell commands: rm -rf (except for temporary file cleanup)

Allowed operations:

• Creating resources (PRs, issues, releases, labels, repos)
• Viewing and listing (status, logs, information, searches)
• Updating and editing existing resources
• Closing PRs/issues (reversible - can be reopened)
• Reverting pull requests (creates a new revert PR)
• Canceling workflow runs (stops execution without deleting data)
• Merging pull requests (after proper review)
• Read-only git operations (git status, git log, git diff)

JSON Output

When the user wants to use --json flags or needs the correct gh CLI JSON field names, see references/json-output.md.

Tips

1. Use --web flag to open items in browser for detailed view
2. Leverage interactive prompts by omitting parameters - most commands support interactive mode
3. Apply filters with --author, --label, --state to narrow down lists efficiently
4. Add --json flag to enable scriptable output for automation
5. Always check --help for valid JSON field names - they differ from GitHub API
6. Use gh repo create --template to scaffold from template repositories
7. Enable auto-merge with gh pr merge --auto for PRs that pass checks
