### Install the ADK + AG-UI bridge
```bash
pip install ag-ui-adk
```
### Read CopilotKit context before each model call
`useAgentContext` entries arrive in ADK session state under
`state["copilotkit"]["context"]`. Add `AGUIToolset()` to the agent and
use a `before_model_callback` to inject those read-only values into the
system instruction.
