Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 2 parameters, no output schema, and no annotations, the description is under-specified. It does not explain the format or constraints of 'message', the meaning or possible values of 'profile', whether the global notice replaces any previous notice, or what the tool returns. Sibling tools are present but not referenced for disambiguation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
