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. While 'Query' implies a read-only operation, it does not mention return format, potential limits, or any other behavioral traits, leaving significant gaps for a tool that fetches all schemas.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
