Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states it 'Get full details' but doesn't specify what 'full details' includes, whether it's a read-only operation, requires authentication, has rate limits, or error behaviors. This leaves significant gaps for a tool that retrieves data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
