Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. The verb 'List' indicates a read-only operation, and the phrase 'the API token can access' adds relevant filtering behavior. However, it does not explicitly state that it does not modify anything or mention any limitations such as pagination or response format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
