Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple lookup tool, the description covers the core purpose and output convention, and references list_game_tables for valid names. However, with no annotations, no output schema, and no parameter descriptions, the missing limit semantics and lack of explicit return-shape guidance leave a moderate gap. It is usable, but an agent would still need to infer or discover important invocation details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
