Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states the action ('Delete') without disclosing critical behavioral traits. It doesn't mention if deletion is permanent, requires specific permissions, affects associated data, or has confirmation prompts, leaving significant gaps for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
