Google has updated its Managed Agents service in the antigravity-preview-05-2026 release. The agent now runs Gemini 3.6 Flash by default. The update introduces environment hooks, token consumption limits, and scheduled triggers — features that turn managed agents into cost-controlled, scheduled workers, according to the company.
Environment hooks are now available in Managed Agents. AI-native investment bank Offdeal uses the post_tool_execution hook to automate image verification. OffDeal describes itself as an AI-native investment bank and its AI analyst as Archie.
Developers can pass max_total_tokens inside agent_config to cap total consumption. When the agent reaches the limit, execution pauses and returns status 'incomplete'. This allows teams to prevent runaway costs in production deployments.
Other new features include scheduled triggers for automating recurring agent tasks and an Environments API to list, inspect, and delete sandbox sessions. Managed agents are now available on free tier projects, lowering the barrier for experimentation.
