The original normalize_messages() used isinstance(block, dict) to filter content blocks, but Anthropic SDK returns pydantic model objects (e.g. ToolUseBlock, TextBlock), not plain dicts. This caused tool_use blocks to be silently dropped, leading to 'tool_result tool_use_id not found' errors (400) on the next API call. Added _block_to_dict() helper that converts SDK objects via model_dump() or vars() fallback, and removed the isinstance(block, dict) guard so all content blocks are properly serialized.

normalize_messages()usesisinstance(block, dict)to filter content blocks, but the Anthropic SDK storesresponse.contentas pydantic model objects (ToolUseBlock,TextBlock), not plain dicts. This silently drops all tool_use blocks during normalization, so the subsequenttool_resultreferences an id the API never saw.Fix
