Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. 'Delete' implies a destructive mutation, but it doesn't specify whether this is permanent, requires specific permissions, affects related data, or has rate limits. The description lacks crucial context for a mutation operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
