github-actions（GitHub Actions 自动化）

Github Actions

When to Use This Skill

USE when:

• Building CI/CD pipelines for GitHub repositories
• Automating tests across multiple OS/language versions
• Creating release and deployment workflows
• Publishing packages to npm, PyPI, Docker Hub
• Automating issue triage and PR management
• Scheduling periodic maintenance tasks
• Building reusable workflow components
• Implementing GitOps deployment patterns

DON'T USE when:

• Repository not hosted on GitHub (use Jenkins, GitLab CI)
• Need complex DAG-based workflow orchestration (use Airflow)
• Require visual workflow design (use n8n, Activepieces)
• Self-hosted runners not available for compute-intensive tasks
• Need real-time event processing (use dedicated message queues)

Prerequisites

GitHub Repository Setup

# Create workflow directory
mkdir -p .github/workflows

# Verify GitHub CLI installed
gh --version

# Authenticate with GitHub
gh auth login

# Check workflow permissions
gh api repos/{owner}/{repo}/actions/permissions

Local Testing with act

# Install act for local workflow testing
# macOS
brew install act

# Linux
