invoking-antigravity

Install and drive Google's Antigravity CLI (`agy`) as a non-interactive sub-agent. Use when orchestrating agy, running Antigravity agents from a script or sandbox, delegating a task to Google's agent harness, or wanting a Gemini-backed peer agent alongside Claude.

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 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

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.

Decide which model, effort level, and cascade shape each subagent gets, and how to keep improvement loops safe (evaluator-as-selector, stop on regression). Routes on measured cost-per-completed-task rather than per-token price, because a tier's token count varies more by task shape than price varies across tiers. Covers per-model effort semantics, the concision lever, cascade preconditions, context handoff, and watching a subagent fan-out live. Use when choosing a subagent's model or effort, when choosing how to escalate a failed attempt, or when asked which model or effort a task should get. Grounded in a 2026-07 calibration, a 2026-08 coding-cost study, a 2026-09 seeded-bug repair battery, a 2026-10 Haiku 5.5 ladder priced per spawn, and a 2026-10 retry-versus-escalation ladder on 295 SWE-bench Verified tasks; Managed Agents API specifics are operational, not calibrated.

Pre-change blast-radius report for a symbol or file. Walks tree-sitting references, augments with a plain-text scan over non-parsed files (configs, plain docs), and clusters affected sites by feature (`_FEATURES.md`) or top-level package. Use when about to refactor, rename, or delete something in a repo you don't own — "what breaks if I change `validateUser`", "who calls this", "is this safe to remove", "where is this used", "blast radius", "impact analysis". This is the CONVERGENT pre-change risk skill — for "what is this repo?" use exploring-codebases; for "where is X?" use searching-codebases.

Read Bluesky/ATProto without depending on Bluesky's AppView — interactions on a user's posts, thread replies, any repo's records, network-wide backlinks across every lexicon, an account's handle and PDS history, which collections are active network-wide, and layer-by-layer outage diagnosis. Use when bsky.app or the AppView is down or slow, when a Bluesky read returns timeouts or 5xx, when asked who liked/replied/quoted/reposted something, when pulling live Bluesky context cheaply, when reading records straight from a PDS, when asked who references a record or account anywhere on the network, whether an account has changed handle or migrated servers, or which lexicons and non-Bluesky apps are active on atproto. Complements browsing-bluesky, which routes everything through the AppView and fails when it does.
