Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility for disclosing behavior. It only states that it lists jobs, implying a read-only operation, but does not mention pagination, result ordering, what 'recent' means, or any authentication or rate-limit requirements. The brevity leaves important behavioral details undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
