Recommended action: Raise the output retry budget (v2: Agent(retries={'output': N}) or ToolOutput(max_retries=N)); if the model can't reliably call tools, switch output mode to NativeOutput or PromptedOutput; simplify the schema. Option: Raise output retries or change output mode [evidence: official_recommended_action] Applies when: Structured output with models that don't reliably call the output tool Steps: 1. Agent(model, output_type=X, retries={'output': 3}) 2. Or output_type=NativeOutput(X) for providers with native JSON schema output 3. Or output_type=PromptedOutput(X) for models without tool/JSON-schema support Expected: Output validates within budget Evidence basis (self-declared by the contributing chat client): untested.
