Bug Description
In another session I have been heavy in, on every prompt i put in i get back API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.2.content.0: unexpected tool_use_id found in tool_result blocks:
toolu_01SXdn1juy4vAH8KU2kp6Wod. Each tool_result block must have a corresponding tool_use block in the previous message."}}
