Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It clearly indicates a destructive cascading operation ('Delete API specification and all related endpoints/schemas'), which is valuable, but it omits important details such as irreversibility, permission requirements, or whether deletion is hard or soft.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
