Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool archives/deletes multiple tasks, implying a destructive mutation, but lacks details on permissions needed, whether deletion is reversible, rate limits, error handling for invalid IDs, or what the response contains. This is inadequate for a mutation tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
