act: Workflow Automation for AI Agents | OpenAgentSkill

Overview

Act

Overview

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

Instructions

Step 1: Install

brew install act

Step 2: Run Workflows

act                          # run push event
act pull_request             # run PR event
act -j test                  # run specific job
act -W .github/workflows/ci.yml  # specific workflow
act --secret-file .env.secrets   # with secrets

Step 3: Configuration

# .actrc — Default settings
-P ubuntu-latest=catthehacker/ubuntu:act-latest
--env-file .env

Step 4: Debug

act -n    # dry run
act -v    # verbose
act -l    # list workflows

Guidelines

First run downloads Docker images (~1-3GB).
Not all GitHub Actions features work locally (e.g., OIDC tokens).
Use micro images for faster runs.
Great for iterating on CI without waiting for GitHub runners.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: Apache-2.0

Dependency or permission surface needs review
Permission surface may require sandboxing
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Stars/forks activity: 145 stars, 16 forks; issue activity unavailable in current metadata
Dependency/runtime risk: command execution surface, credential or environment access
Permission surface: secrets or environment access, shell or command execution

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
