# Antigravity CLI Sub-Agents Google Antigravity CLI (`agy`) is an autonomous terminal coding agent (Gemini and other models) that can read a repo, edit files, and run commands. This skill uses its non-interactive print mode to run **delegated jobs**: you write a self-contained task prompt, launch `agy -p` in the background, keep doing your own work, then collect and verify the result. Treat an agy job like a contractor you briefed over email: it only knows what's in the prompt and the directory you point it at, and its work is unverified until you check it. ## Resolving the binary After install, `agy` is normally on your `PATH`. If a tool-spawned shell can't find it (some shells don't inherit a freshly updated PATH), fall back to the full path: - **Windows:** `%LOCALAPPDATA%\agy\bin\agy.exe` (in Bash-style shells: `"$LOCALAPPDATA/agy/bin/agy.exe"`) - **macOS / Linux:** check `which agy` **Critical: always close stdin.** `agy` blocks forever (0% CPU, no output, even in print mode) when stdin is an open pipe, which is exactly what non-interactive tool shells give it. Launch jobs with `</dev/null` appended (POSIX shells), or from PowerShell via `cmd /c '... < NUL'`. A "stalled" job with an empty log almost always means stdin was left open — kill it and relaunch with stdin closed. ## Preflight (once per session) Before the first job of a session, verify auth with a cheap probe: ```bash agy -p "Reply with exactly: OK" --print-timeout 60s </dev/null ``` - Replies `OK` → a...
