Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (3 parameters, no output schema, no annotations), the description is too sparse. It fails to describe return values, usage context, or parameter specifics, leaving the agent with insufficient information to correctly invoke and interpret the tool. The single-sentence description covers the purpose but not the operational context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
