Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It indicates a read operation ('Get') but fails to disclose any behavioral traits such as error handling on missing ID, authentication requirements, or rate limits. The minimal description provides insufficient transparency for a safe agent invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
