Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It mentions 'and all its data,' indicating cascading deletion scope, but fails to disclose critical behavioral traits: irreversibility, the purpose of the 'confirm' parameter, or whether deletion is immediate/async. The '[UNIFIED]' prefix is unexplained metadata that provides no behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
