Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It only says 'Run an ERPNext report,' offering no information about side effects, read-only nature, required permissions, or output characteristics. The lack of any behavioral context makes it nearly useless for understanding tool behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
