QA: Declarative Generative UI — Spring AI

Prerequisites

• Spring AI backend is up with the generate_a2ui tool registered
• OPENAI_API_KEY is set (the dynamic-A2UI tool makes a secondary LLM call)

Test Steps

• Navigate to /demos/declarative-gen-ui
• Click the "Show a KPI dashboard" suggestion
• Verify a dashboard with 3-4 metric cards renders inline
• Click the "What's the weather like?" suggestion (or similar)
• Verify the agent generates a branded UI card using the catalog components

Expected Results

• a2ui.injectA2UITool: false keeps the tool owned by the Spring backend
• Catalog schema is serialized into copilotkit.context so the Spring tool's LLM knows available components
• Rendered components match the catalog definitions in ./a2ui/renderers.tsx
