# 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
