### Install the ADK + AG-UI bridge
```bash
pip install ag-ui-adk
```
### Add `AGUIToolset()` to your agent
Agent config flows from the UI through `useAgentContext`. With
`AGUIToolset()` wired into your `LlmAgent`, the context entry is
available in session state on every turn — read it inside a
`before_model_callback` to inject preferences into the system prompt.
