Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. 'Delete a script' merely restates the tool's name and does not reveal any behavior such as permanence, permission requirements, or cascading effects. This is a complete lack of transparency for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
