Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. The verb 'list' clearly implies read-only enumeration, but the description does not explicitly state safety, authentication needs, pagination, or scope limitations (e.g., whether all applications across all users are returned). It is adequate for a simple list operation 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.
