Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states that it deletes a company but does not reveal side effects, whether deletion is reversible, permission requirements, or impact on related data. The existence of a 'restore_company' sibling is not referenced, leaving uncertainty about whether this is a soft or hard delete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
