Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states the basic function without mentioning safety (e.g., read-only), side effects, authorization requirements, or rate limits. The agent learns nothing beyond the operation's purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
