Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity (2 required params, no enums, no output schema), the description could still be more complete. It does not mention return value, success/failure conditions, or any constraints like name uniqueness. Incomplete for an agent to use confidently.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
