Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The `[read]` tag is consistent with the annotations (readOnlyHint=true, idempotentHint=true) and the description identifies the exact returned field plus a sample value, adding some context. However, it does not describe behavior when both identifiers are supplied or when neither is, nor any error semantics, which is the main gap annotations don't cover.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
