Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses the meaningful protection constraint on the Overview dashboard, but says nothing about irreversibility, required permissions, or what happens to contained views/cards. A destructive tool with zero annotation coverage warrants more disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
