Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations only include the title, missing readOnlyHint and destructiveHint. The description says 'add', implying mutation, but no details on permissions, side effects, or whether it overwrites existing content. With no annotation support, the description fails to disclose behavioral traits beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
