Summary
Test shape
The regression test runs an untouched image tool result through:
LLMRequest → OpenCode AI SDK lowering → real @ai-sdk/mistral provider → intercepted requestIt asserts the complete Mistral
messagespayload: the tool result remains a tool message and the image arrives afterward as a native userimage_url. The test never calls the fallback directly and makes no provider request.Validation
