Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('Delete') which implies a destructive operation, but doesn't specify whether deletion is permanent, requires admin permissions, affects network traffic immediately, or has confirmation prompts. For a destructive tool with zero annotation coverage, this leaves critical behavioral traits undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
