Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full behavioral burden. It states the operation is a read-only 'get' that returns a list with descriptions, but it does not disclose error behavior, rate limits, or any potential side effects. For a simple list tool this is minimal, and the agent is left to infer that it is safe.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
