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.
When to use
- Orchestrating
agyas 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
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:
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:
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/antigravity-oauth-token;
later agy -p calls run silently. Complete the login within a few minutes —
an idle container pause kills the broker's agy process.
3. Orchestrate
agy --dangerously-skip-permissions -p "<task>"
Place every flag before -p — it treats the next argument as the prompt.
Add --add-dir <path>, --print-timeout 10m, or --conversation <id> as
the task needs.
Reuse auth on a fresh container
Save ~/.gemini/antigravity-cli/antigravity-oauth-token and write it back
(with the SSH vars set) — its refresh_token is durable, so no repeat
OAuth. Keep the file out of git and logs; it is a personal Google credential.

Reads the visual content of slides, pages, and images the way a human would, not just their embedded text. Use when a PPTX or PDF has image slides, screenshots, charts, scanned figures, or flattened-to-image layouts that the built-in pptx/pdf skills read as empty; when asked to transcribe, describe, OCR, or extract what is shown in an image, slide deck, or document page; or when embedded-text extraction returned little or nothing from a visually rich file. Triggers on 'read this deck', 'what's on these slides', 'transcribe', 'OCR', 'extract text from image', 'describe this chart/diagram', .pptx/.pdf/.png/.jpg with visual content.
