A one-command scaffold for a non-interactive AI agent harness that runs on the GitHub Actions runner — the 9th MetaHarness host (ADR-033) and the only one built for CI/CD.
Every other MetaHarness host is interactive: a human starts a session and watches the agent work. GitHub Actions is different in kind. There's no human at the keyboard — execution is triggered by a webhook (a push, a pull request, an issue comment, or a schedule), the "operator" is the runner, and the harness must complete its task autonomously, emit structured output, and exit cleanly.
@metaharness/github-actions is a thin wrapper around the metaharness CLI. Running it is equivalent to npx metaharness my-bot --template minimal --host github-actions.
