Agent Approve for Google Antigravity
Mobile approvals, activity monitoring, subagent tracking, and follow-up input for Google Antigravity
Agent Approve gives you centralized control over Google Antigravity from your phone. Approve or deny tool calls, track subagent lifecycle events, and see model calls, prompts, responses, plans, messages, questions, and stop events in one activity history.
Antigravity support uses the native plugin and hook system: PreToolUse blocks for approval, telemetry flows through the existing batched event queue, and Stop can wait for a follow-up instruction from your iPhone or Apple Watch.
Quick start
Download Agent Approve from the App Store and complete onboarding.
Run npx agentapprove on your development machine and select Antigravity.
The installer writes the Agent Approve plugin under ~/.gemini/config/plugins/agentapprove/.
Start using Antigravity — approval requests and activity events arrive on your phone.

Capabilities
Good to know
Native hook coverage – PreToolUse, PostToolUse, PreInvocation, PostInvocation, and Stop route through one dispatcher.
Subagent visibility – invoke_subagent, define_subagent, and manage_subagents are mapped to subagent lifecycle and management events instead of generic tool rows.
Follow-up commands – The Stop hook can hold the turn open and return a voice or text follow-up from your phone.
Encrypted telemetry – Non-blocking events use the existing batched event queue and end-to-end encrypted payload path.
Gemini transition – Google transitioned Gemini CLI users to Antigravity on June 18, 2026, so new Google-agent setup should generally use Antigravity.
Use cases
Approve sensitive Antigravity tool calls from iPhone or Apple Watch while safe actions keep moving under shared policy.
See subagents start, stop, get defined, or get managed alongside the parent conversation instead of losing work in nested runs.
Block destructive shell or file operations with the same deny rules you use for Cursor, Claude Code, Codex, and other agents.
Send a follow-up instruction from your phone when Antigravity reaches a stop point.
