## Reported context
Google recently announced(https://developers.googleblog.com/an-important-update-transitioning-gemini-cli-to-antigravity-cli/) the deprecation of Gemini CLI in favor of their new agent-first development platform,
Antigravity CLI
. For individual and free-tier users, Gemini CLI requests will stop being served on
June 18, 2026
.
Since Tolaria relies heavily on integrated terminal workflows, we should treat this as a high-priority migration. Transitioning to Antigravity CLI not only prevents a hard breaking change next month but also introduces major performance and architectural upgrades.

### 🚀 Why This is a Significant Upgrade for Tolaria
*
Massive Speed & Responsiveness Boost
*
The Problem:
Gemini CLI is likely Node.js-based, causing noticeable startup latency and overhead when interfacing with our backend.
*
The Fix:
Antigravity CLI is compiled in
Go
, offering significantly faster execution, snappier terminal responses, and negligible startup overhead.
*
Asynchronous Multi-Agent Workflows
* It natively orchestrates multiple subagents in the background. We can trigger large-scale code refactors or complex repository analyses without locking up the user's active terminal session.
*
Unified Agent Architecture
* It shares a unified server-side harness with Antigravity 2.0. Moving to it ensures that any future core agent upgrades roll out to Tolaria seamlessly without breaking local hooks.
*
Feature Parity Maintained
* Critical components we rely on—such as Agent Skills, Hooks, Subagents, and Extensions—are preserved as Antigravity plugins.
