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. 'Get' implies a read-only operation, which is appropriate, but no further behavior (e.g., error handling, permission requirements) is described. The minimal disclosure is acceptable for a simple read but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
