Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With zero parameters, no output schema, and no annotations, the description is all there is. For a simple getter, 'Get Priya Gautam's professional experience' covers the essentials, but given the existence of siblings like search-priya-profile and search-profile, the description could clarify what is included/excluded in 'professional experience' versus what skills/projects/education tools cover. There's ambiguity about the scope of the returned content.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
