What does the Act Local CI skill do?

It allows you to run and test your GitHub Actions workflows locally using the act tool, helping you catch errors and validate pipeline logic before pushing code to a remote repository.

How does this improve development speed?

By running CI jobs locally, you eliminate the overhead of pushing to GitHub and waiting for cloud runners, resulting in much faster iteration and debugging cycles.

Can I test workflows that require secrets?

Yes, the skill supports secure secret injection through command-line flags or .secrets files, allowing you to simulate production environments safely.

Does it support matrix builds?

Absolutely. You can run all matrix combinations or target specific ones to ensure your software builds correctly across different OS and environment configurations.

Do I need Docker to use this skill?

Yes, Docker must be installed and running on your local machine because act uses Docker containers to simulate the GitHub runner environments.

Deployment & DevOps

Validates and runs GitHub Actions workflows locally to accelerate CI/CD development and debugging cycles.

About

Act Local CI enables developers to simulate the GitHub Actions environment on their local machine using nektos/act, allowing for immediate feedback on pipeline changes without pushing to a remote repository. It provides comprehensive support for job selection, secret management, and matrix builds, making it an essential tool for debugging complex CI scripts, testing environment variables, and ensuring workflows are production-ready before they ever hit the server. This skill streamlines the DevOps workflow by catching configuration errors early and reducing the reliance on cloud-based runner wait times.
