Reason: when toolName:get_stock_price failed to match (claude-sdk-python backend appears not to forward the tool definition uniformly on the second turn), the userMessage-only fallback returned plain content with no toolCall \u2192 no custom-wildcard card \u2192 D5 assertion fails with 'missing tool name [get_stock_price]'. Canonical pattern (no gate on tool-emit, toolCallId narration above for first-match-wins) lets the tool call always emit; the toolCallId narration fires on iteration 2 regardless of which tools the backend forwards." }, "fixtures": [ { "_comment": "custom-catchall: weather in Tokyo follow-up after get_weather tool result.
