Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter, the schema covers parameter semantics, but the description fails to provide usage context, behavioral expectations, or return value information. With no annotations and no output schema, the description is too sparse to fully equip an agent to use the tool correctly. It leaves important questions unanswered, such as what 'details' are included and how the application ID should be obtained.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
