Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits on its own. It only states 'Delete an AI agent' without mentioning irreversibility, potential cascading deletion of associated data, or whether the operation requires confirmation. This is a significant gap for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
