# Antigravity native harness: end-to-end dev & testing (local server/runner) The `antigravity-native` harness wraps the **real Antigravity `agy` TUI** (the `agy` CLI, installed from `antigravity.google/cli/install.sh`). `omnigent antigravity` ensures a host daemon, the daemon-spawned **runner** launches `agy` in a runner-owned **tmux** terminal, and your TTY attaches to it. This is **not** the in-process `antigravity` Gemini-SDK harness — that one runs `google-antigravity` with a Gemini *API key*; this one drives the OAuth-only `agy` CLI and mirrors it over **connect-RPC**. This skill is the proven recipe for running it **for real against a live local server + runner** — not just the unit tests. > Like the other native harnesses, the runner imports from your **current > checkout**, so testing here exercises exactly the code you're on. (CWD/venv > selects the code, not `PYTHONPATH`.) ## What actually runs where ``` your TTY ── (attach / pexpect) ──► omnigent antigravity (CLI, local) │ ensures ▼ host daemon ──► local Omnigent server (AP) │ spawns ▲ ▼ connect-RPC │ HTTP runner ── launches ──► agy (TUI, in tmux) │ │ ...
