  • System prompt as top-level parameter (not a message)
  • Content blocks for text, tool_use, tool_result, thinking
  • Tool definitions as name/description/input_schema
  • Only "user" and "assistant" roles allowed in messages
  • Tool results sent as "user" role with tool_result content blocks
  • Multimodal content blocks (text + images)
