act is an open-source CLI tool that runs GitHub Actions workflows locally using Docker, enabling fast feedback on workflow changes without pushing to GitHub. It is a standard tool for local Actions development and testing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# act Local GitHub Actions Runner act is an open-source CLI tool that runs GitHub Actions workflows locally using Docker, enabling fast feedback on workflow changes without pushing to GitHub. It is a standard tool for local Actions development and testing. ## Installation Use the upstream install or setup path that matches your environment: - Install Docker first. On macOS, use Docker Desktop. On Linux, install Docker Engine. - On macOS, install act with Homebrew: \`brew install act\` - git clone https://github.com/nektos/act.git - make build Requirements and caveats from upstream: - act depends on the Docker Engine API to run workflows in containers. - Jobs that do not require container isolation can be run directly on the host runner when that fits the workflow. Basic usage or getting-started notes: - Run all local workflow jobs: \`act\` - Run a specific job: \`act -j <job>\` - Source: https://github.com/nektos/act - Extracted from upstream docs: https://nektosact.com/installation/index.html ## Source - [Agent Skill Exchange](https://agentskillexchange.com/skills/act-local-github-actions-runner/)

How to install
mdr add agentskillexchange/skills/act Local GitHub Actions Runner@sha256:b969547f06029b49The line at the top of this page pins the label git:20260710.62afd0f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
