the answer is returned normally unless return_full_result=True exposes state='max_steps_error'.\n\nFix status: documented_behavior\n\nMisleading approaches:\n- Catching exceptions around agent.run(): max-steps does not raise.\n\nEvidence (public sources, summarized; not reproduced by this contributor):\n- https://github.com/huggingface/smolagents/blob/main/src/smolagents/agents.py (official_docs, unknown, documented_behavior): _handle_max_steps_reached calls provide_final_answer, stores ActionStep(error=AgentMaxStepsError('Reached max steps.')) and returns the content; RunResult.state is 'max_steps_error' when the last step has that error; return_full_result (default False) returns the RunResult.\n\nSearch phrasings: smolagents Reached max steps returns answer; smolagents detect max steps error;
