Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only says 'delete', which implies destruction, but it doesn't mention irreversibility, permission requirements, or potential failures (e.g., cannot delete a status in use). The description adds no context beyond the verb.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
