Act

Overview Act runs GitHub Actions workflows locally using Docker. Test and debug CI pipelines without pushing to GitHub. Supports most GitHub Actions features.

Overview

The Act skill, sourced from the TerminalSkills/skills repository on GitHub, allows AI agents to execute GitHub Actions workflows in a local environment. By utilizing Docker containers to simulate GitHub runners, this tool enables developers to test and debug CI/CD pipelines without the need for frequent commits or remote execution. It supports a broad array of standard GitHub Actions features, providing a reliable way to validate automation logic and syntax. This skill is compatible with various AI agents, including Claude and Gemini, facilitating a more efficient DevOps workflow by offering immediate feedback on pipeline configurations within the local development setup.

Use Cases

Local debugging of GitHub Actions workflows to identify and fix syntax errors.
Testing CI/CD pipeline modifications without triggering remote GitHub runners.
Validating automation scripts within a controlled Docker-based environment.

Install Notes

# Review source first
open https://github.com/TerminalSkills/skills/blob/main/skills/act/SKILL.md

Copy or clone the skill folder into your agent skills directory after reviewing its instructions and scripts.

Security Notes

The Act skill requires a functional Docker installation on the host machine to manage containerized workflow execution. Users must manage local secrets and environment variables carefully, as the tool interacts directly with the local container runtime to replicate GitHub's infrastructure.

DevOps

Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions; use `gh` to inspect checks and logs, summarize failure context, draft a fix plan, and implement only after explicit approval. Treat external providers (for example Buildkite) as out of scope and report only the details URL.
