Streamlines the local execution and debugging of GitHub Actions workflows using the act CLI and Docker.
This skill provides comprehensive guidance for using 'act' to run GitHub Actions locally, enabling developers to test CI/CD pipelines without pushing to remote repositories. It covers everything from basic CLI commands and Docker runner configuration to advanced secrets management, environment variable handling, and interactive debugging. By simulating the GitHub environment on a local machine, it significantly reduces feedback loops and prevents common workflow errors before they reach production.
