QA: Tool Rendering (Default Catch-all) — Langroid

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy (check /api/health)
• Agent slug tool-rendering-default-catchall is registered at /api/copilotkit

Test Steps

1. Basic Functionality

• Navigate to the tool-rendering-default-catchall demo page
• Verify the chat interface loads in a centered full-height layout (max-width 4xl, rounded-2xl)
• Verify the chat input placeholder "Type a message" is visible
• Send a basic message and verify the Langroid agent responds

2. Feature-Specific Checks — Built-in Default Tool-Call UI

The page calls useDefaultRenderTool() with NO config, so every tool call routes to CopilotKit's built-in DefaultToolCallRenderer.

Suggestions

• Verify "Weather in SF" suggestion pill is visible
• Verify "Find flights" suggestion pill is visible
• Verify "Weather in Tokyo" suggestion pill is visible

get_weather renders via the built-in default card

• Click "Weather in SF"
• Verify a default tool-call card appears with get_weather as header
• Verify status transitions Running -> Done
• Verify no data-testid="custom-catchall-card" and no data-testid="weather-card" — only the built-in card paints.

search_flights renders via the same built-in card

• Click "Find flights"
• Verify a second default card with search_flights header
• Verify status lands on Done

3. Expected

• No per-tool branded cards
• No custom wildcard renderer
• Every tool call uses the package-provided default card
