GitHub CLI Workflows

Purpose

Enable autonomous creation and execution of GitHub workflows using the official GitHub CLI (gh). This skill provides the knowledge and patterns needed to work with pull requests, issues, GitHub Actions, and the GitHub API through command-line operations.

Core Philosophy

Work autonomously within user-specified boundaries, respecting the current Claude Code mode (accept edits vs plan mode). Design multi-step workflows tailored to specific needs, handle errors intelligently, and always verify context before executing repository operations.

Prerequisites

Required Tools

GitHub CLI must be installed. Check with:

gh --version

If not installed, guide the user to https://cli.github.com/ for installation instructions (brew, apt, etc.).

Authentication Status

Do not proactively check authentication, but be prepared to recognize and diagnose authentication errors. When auth issues occur, guide the user to resolve them (see references/troubleshooting.md).

The Golden Rule: Use --help First

CRITICAL: Every gh command and subcommand supports --help to display comprehensive usage information, including:

• Available flags and options
• Argument formats
• Detailed examples
• Exit codes
• Related commands

When to use --help:

• Before constructing any complex command
• When uncertain about flag syntax
• When encountering errors (verify command structure)
• To discover available subcommands
• To check for new features or options

Examples:

gh --help                    # List all commands
gh repo --help               # Repository commands
gh repo create --help        # Specific command details
gh pr create --help          # PR creation options
gh api --help                # API usage with examples

Pattern: gh <command> <subcommand> --help works at every level. Always check help before guessing command syntax.

Repository Context

Before executing repo-specific commands, verify repository context:

gh repo view

This confirms:

• Current repository (owner/repo)
• Authentication works
• Proper permissions exist

When context is unclear, infer from the current directory unless explicitly specified otherwise. Use -R owner/repo flag to override when working across multiple repositories.

Core Capabilities

Pull Requests

Create, review, comment, merge, and manage pull requests programmatically.

Common operations:

• Create PR from current branch
• List open PRs with filters
• View PR details and checks
• Review and comment on PRs
• Merge PRs with various strategies
• Checkout PR branches locally

See references/pr-workflows.md for detailed patterns.

Issues

Triage, label, comment, and manage issues systematically.

Common operations:

• List new/open issues
• Create issues with templates
• Add/remove labels
• Comment and discuss
• Close with resolution notes
• Link to PRs

See references/issue-workflows.md for detailed patterns.

GitHub Actions

Monitor workflow runs, analyze failures, view logs, and trigger reruns.

Common operations:

• List workflow runs
• Check run status and conclusion
• Download and analyze logs
• Rerun failed workflows
• Cancel running workflows
• View workflow definitions

See references/actions-workflows.md for detailed patterns.

GitHub API

Execute custom operations not covered by core commands using gh api.

Common operations:

• GraphQL queries for complex data
• REST API operations
• Pagination handling with --paginate
• JSON output parsing with --jq
• Custom integrations

See references/api-usage.md for detailed patterns and examples.

Working with JSON Output

Many gh commands support --json for structured output and --jq for filtering.

When to use JSON:

• Parse results programmatically
• Extract specific fields
• Process multiple items
• Make decisions based on output

When to use human-readable:

• Show output directly to user
• Initial exploration
• Debugging

Pattern: Fetch with JSON, format for humans in responses:

# Get structured data
gh pr list --json number,title,author,state

# Extract specific fields
gh pr view 123 --json title,body --jq '.title'

# Process and format for user display

Always show users formatted, readable output in responses, even when working with JSON internally.

Destructive Operations

Always ask user confirmation before executing operations that:

• Close issues or PRs
• Delete branches
• Merge pull requests
• Archive repositories
• Modify labels or milestones permanently

Offer dry-run option when available:

I can perform a dry-run first to show what would happen. Would you like me to:
1. Execute the operation now
2. Perform a dry-run and report the outcome
3. Show you the exact command to review first

Use --dry-run flags where supported (check --help for availability).

Error Handling Workflow

When a gh command fails, follow this sequence:

1. Review Command Output

Most errors have clear, actionable messages. Read the error carefully:

• Authentication required
• Permission denied
• Resource not found
• Invalid arguments
• Rate limit exceeded

2. Search Troubleshooting Documentation

Use grep/search tools to find relevant information in references/troubleshooting.md:

# Search for specific error patterns
grep -i "authentication" references/troubleshooting.md

Avoid reading the entire troubleshooting file unless necessary.

3. Verify Command with --help

Check that command syntax matches the help documentation:

gh <command> <subcommand> --help

Common issues:

• Wrong flag names
• Missing required arguments
• Incorrect argument order
• Flag used with wrong command

4. Report to User

If the error persists after these steps, report detailed diagnostics:

• Exact command executed
• Complete error output
• Steps already attempted
• Relevant troubleshooting findings
• Suggested next actions

Ask for user guidance on how to proceed.

Autonomy and User Boundaries

Respect Current Mode

In accept-edits mode:

• Make changes directly
• Execute commands autonomously
• Commit and push as needed

In plan mode:

• Create detailed implementation plans
• Get user approval before execution
• Document each planned step

User-Specified Boundaries

Honor any constraints the user provides:

• Repository limits
• Branch protections
• Label conventions
• Review requirements
• Approval workflows

Workflow-Specific Autonomy

Fix Failing CI/CD: View run → Download logs → Analyze errors → Suggest fixes → Implement → Push → (Rerun only if workflow won't auto-trigger)

Triage Issues: Execute based on user-specified parameters (which labels to apply, what comments to add, etc.)

Implement PR Feedback: Read comments → Make changes → Commit → Push (respecting current mode)

Create Pull Requests: Verify branch → Push if needed → Create PR with description → Link issues (respecting current mode)

Be as autonomous as possible within established boundaries.

Common Patterns

For frequently-used patterns and workflows, see references/common-patterns.md:

• Authentication checks and recovery
• Multi-repository operations
• Batch processing issues/PRs
• CI/CD integration patterns
• Error recovery strategies
• Working with draft PRs
• Managing labels and milestones
• Using PR templates

Command Discovery

Discover available commands at any level:

gh --help                    # All core commands
gh pr --help                 # PR subcommands
gh issue --help              # Issue subcommands
gh run --help                # Actions run commands
gh workflow --help           # Workflow commands
gh api --help                # API usage (extensive examples)

Each help page includes:

• Command descriptions
• Available subcommands
• Flags and options
• Usage examples
• Related commands

Output Visibility

Always show commands before execution so users understand what's running:

Checking repository context with:
$ gh repo view

Creating pull request with:
$ gh pr create --title "feat: Add user authentication" --body "..." --base main

This transparency helps users:

• Understand the workflow
• Learn gh commands
• Verify correctness
• Reproduce manually if needed
