// Dedicated runtime for the Declarative Generative UI (A2UI) cell (Langroid).
|
|
//
|
|
// The unified Langroid agent already owns a `generate_a2ui` tool (see
|
|
// src/agents/agent.py -> GenerateA2UITool). We route this demo here so we
|
|
// can set `a2ui.injectA2UITool: false` — the runtime must NOT auto-inject
|
|
// its own A2UI tool on top of the agent-owned one.
|
|
//
|
|
// The A2UI middleware still runs: it serialises the registered client
|
|
// catalog into the agent's context so the secondary LLM inside
|
|
// `generate_a2ui` knows which components to emit.
