GitHub Actions CI

Overview

GitHub Actions enables automated build, test, and deployment workflows directly in your GitHub repository. This skill should be invoked when setting up CI/CD pipelines for automated testing, code quality checks, and build verification on pull requests and commits.

Core Principles

• Workflow as Code: Define CI/CD pipelines in YAML files stored in the repository
• Trigger Selection: Choose appropriate triggers (push, pull_request, schedule) to balance coverage and speed
• Matrix Strategy: Use matrix builds to test across multiple versions/configurations efficiently
• Artifact Management: Properly configure artifact retention and caching

Preparation Checklist

• Identify the workflows needed (CI, CD, security scans)
• Ensure build and test scripts exist and work locally
• Determine required runtime versions (Node, Python, .NET, etc.)
• Plan secret management for deployment workflows
