Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral disclosure. It says 'Fetch', which implies a non-mutating read, but it does not disclose behavior such as error handling, return format, or access requirements. The description is minimal and leaves some ambiguity, though the operation is simple.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
