Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility for disclosing behavioral traits. It only states that it clears completed/failed tasks but omits important details such as whether the clearing is permanent, whether it blocks, whether it affects running tasks, or if any confirmation is required. This lack of transparency is a significant gap for a potentially 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.
