The A2UI middleware (@ag-ui/a2ui-middleware) forwards injectA2UITool on forwardedProps; ag-ui-langgraph surfaces it into agent state at state["ag-ui"]["inject_a2ui_tool"]. The CopilotKit LangGraph middleware (py + js) now reads that flag and only injects generate_a2ui when it is truthy (opt-in), drops the runtime's render_a2ui so the model sees one A2UI tool, and skips if the agent already defines generate_a2ui. The catalog only binds surfaces; it is no longer the gate. Reverts the earlier runtime-forward + context-channel approach. Deps: ag-ui-langgraph>=0.0.38 (py), @ag-ui/langgraph 0.0.37 (sdk-js), @ag-ui/a2ui-middleware 0.0.6 + @ag-ui/langgraph 0.0.37 (runtime); .npmrc min-release-age exclude for @ag-ui/a2ui-middleware. Showcase langgraph pins bumped to copilotkit==0.1.94a3 / sdk-js 1.59.3-alpha.3 / @ag-ui/langgraph 0.0.37.
