Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses that the tool returns authoritative descriptions, aliases, relationships, and source documents, indicating a read-only lookup. However, it does not mention behavior for unknown terms, case sensitivity, or potential errors, which limits full transparency for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
