Antigravity CLI

Dynamic subagents, single-session routing, and interactive authentication.

Antigravity CLI (agy) creates an isolated-context subagent for each task and can dispatch independent tasks together. It exposes one model per session rather than a per-call model or effort knob, so woostack resolves one run model and every task tier collapses to it.

The spawn primitive does not expose a per-call working directory. Each worker receives the expected worktree through the dispatch prompt and self-pins before writing. Antigravity authenticates through the system keyring and Google Sign-In; it has no documented non-interactive API-key path, so it cannot run headless in ephemeral CI. Provider exhaustion surfaces as an error, with no documented host-owned fallback.

For detection, exact orchestration behavior, per-skill instructions, and degradation rules, read the canonical Antigravity reference.
