Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It correctly discloses that the tool fetches full details and lists returned fields, but lacks information about potential errors, rate limits, or permissions. For a simple read operation, this is minimally adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
