# Invoking Antigravity Run Google's Antigravity CLI (`agy`) headless, then call `agy -p "<task>"` as an orchestrated sub-agent on Google's harness (Gemini 3.5 Flash). Install, authenticate once, orchestrate. For the *why* behind any step — the 30 s timeout, the keyring fallback, the token format, network hosts, troubleshooting — read [references/auth-internals.md](references/auth-internals.md). ## When to use - Orchestrating `agy` as a sub-agent: shell out, capture stdout, fold back. - Running Antigravity agents from a script, CI, or sandboxed container. - Wanting a second opinion from Google's harness alongside Claude. For interactive local use, skip this — run `agy` directly and it opens a browser. ## 1. Install ```bash curl -fsSL https://antigravity.google/cli/install.sh | bash ``` Idempotent, ~3 s, installs `~/.local/bin/agy`. ## 2. Authenticate — once, human-in-the-loop Export these in every shell that runs `agy`, so it stores the token in a file rather than an OS keyring: ```bash export SSH_CONNECTION="203.0.113.1 50000 203.0.113.2 22" export SSH_CLIENT="203.0.113.1 50000 22" export SSH_TTY="/dev/pts/0" ``` Run the broker, then relay the login to a human: ```bash python3 scripts/agy_auth_broker.py & # spawns agy, captures the OAuth URL sleep 15 && cat /tmp/agybroker/url # a human opens this and consents printf '<code>' > /tmp/agybroker/code # paste the authorization code back ``` `agy` writes the token to `~/.gemini/antigravity-cli/antigr
