Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given three parameters, no output schema, and no annotations, the description covers the main operational aspects: entity-based query, multi-hop depth, semantic association discovery, and the underlying edge types. It does not describe return-value structure or explicitly address edge cases, but for a retrieval-oriented tool the provided context is largely sufficient. The main gap is the absence of any statement about safety or side effects, but the description's '检索' wording implies read-only behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
