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. 'Delete a page' implies a destructive operation, but it doesn't mention permissions required, whether deletion is permanent or reversible, what happens to associated content, or any rate limits. For a destructive tool with zero annotation coverage, this is dangerously inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
