Gemini 3.6 Flash is here, and it brings hooks to control agents
gemini api managed agents now default to gemini 3.6 flash and feature environment hooks for security auditing, impacting production ai workflows.
google updated the gemini api managed agents to default to gemini 3.6 flash, a model optimized for agentic workflows involving reasoning and tool use. the release adds environment hooks, a mechanism that triggers custom scripts or http endpoints on pre_tool_execution or post_tool_execution events to enforce security or linting. this allows teams to audit or reject specific tool calls, such as code execution or file writes, directly within the isolated cloud sandbox.
