Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of 2 undocumented parameters, zero schema descriptions, no annotations, and no output schema, the description is completely inadequate. It fails to explain: (1) how to specify which animation to query, (2) what data structure is returned, (3) the connection-oriented nature implied by the parameters, or (4) the compatibility context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
