Continuum surfaces Antigravity sessions — sometimes labelled Gemini in the Usage tab — through the shared .gemini agent kind in the wire protocol.

​
Requirements

The agy (Antigravity) CLI must be installed. Continuum starts sessions through the headless agy harness; no additional credential configuration is required in Continuum itself.

​
How it integrates

Sessions run through the headless agy harness. Continuum:
  • Reads the conversation database and brain-dir state written by agy.
  • Exposes plan snapshots from conversation state in the Plan pane.
  • Maps Gemini rolling quota into the Usage tab quota gauge.
The user-facing label for these sessions in the Chat and Code tabs is Antigravity. The Usage tab may also show this as Gemini depending on the context.

​
Usage analytics

Gemini token events are parsed from the Antigravity conversation database. Token counts are normalized and priced using the LiteLLM snapshot in the analytics layer.
Antigravity conversation DB ingestion uses SQLite parsing. On watchOS, this code path is gated out at compile time because SQLite links are unavailable; the Watch reads aggregated usage from the paired iPhone instead.

​
Quota gauge

Gemini quota appears in the Usage tab alongside Claude and Codex gauges. The source is the Antigravity session state rather than API response headers.

​
Plan snapshots

When agy generates a plan, Continuum reads it from conversation state and shows it in the Plan card. The Approve button routes through the same daemon handler as Claude and Codex plan approvals.

​
Broadcast

Antigravity / Gemini can participate in the Chat tab’s multi-provider broadcast mode. Send one prompt to multiple providers simultaneously and compare answers side-by-side.
