QA: Tool Rendering (Reasoning Chain) — LangGraph (Python)

Stub — authored for column completeness. This is a testing-kind demo (see kind: "testing" in feature-registry.json) and does not warrant a full manual checklist.

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy

Test Steps

• Navigate to /demos/tool-rendering-reasoning-chain
• Send a multi-tool prompt (e.g. "What's the weather in Tokyo?") and verify reasoning blocks interleave with sequential tool cards (WeatherCard, FlightListCard, or the custom catchall)
• Verify reasoning tokens stream into the custom ReasoningBlock slot alongside the tool cards in the same message view

Expected Results

• Page loads without errors
• Reasoning tokens and tool-call cards render side-by-side in a single sequential chain, each tool matched to its typed renderer
