Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds 'This action is irreversible' beyond the schema, which is a key behavioral trait. However, it does not disclose other aspects like required permissions, cascade effects on child objects (ads), or any side effects. With no annotations, the description partially but not fully carries the behavioral disclosure burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
