Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 3 parameters, no output schema, no annotations, and many sibling tools, the description is insufficient. It does not address return data (e.g., store names, distances), error conditions, or how 'nearby' is defined (e.g., radius default). The agent lacks key information for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
