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. While 'Clear' implies a destructive action, the description doesn't specify whether this operation is reversible, what permissions are needed, or what happens to the logs (permanent deletion vs temporary clearing). It also doesn't mention any side effects or error conditions, leaving significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
