### Install the ADK + AG-UI bridge ```bash pip install ag-ui-adk ``` ### Add `AGUIToolset()` to your supervisor agent Sub-agents are tools on a supervisor `LlmAgent`. The showcase uses `google.genai.Client.models.generate_content` for each sub-agent call — much lighter than spawning a separate `LlmAgent` + `Runner` per delegation. Delegation events are written to `tool_context.state` and flow back to the UI through CopilotKit's shared-state channel. See `src/agents/subagents_agent.py` for the supervisor + three sub-agents pattern with a live delegation log.
