QA: Tool Rendering (Reasoning Chain) — Spring AI

Prerequisites

• Spring AI backend is up with get_weather and search_flights tools

Test Steps

• Navigate to /demos/tool-rendering-reasoning-chain
• Send: "Check weather in Tokyo, then search for flights SFO to JFK"
• Verify WeatherCard renders for the weather tool call
• Verify FlightListCard renders for the search_flights tool call
• If the adapter emits reasoning events, verify the ReasoningBlock renders between tool calls

Expected Results

• Per-tool custom renderers fire for get_weather and search_flights
• Catchall renderer handles any unexpected tools
• Reasoning slot renders when backend provides reasoning content
