Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must convey safety and behavioral traits. It only says 'Get an automation by ID' without disclosing what is returned, error handling (e.g., 404 if not found), permissions, or rate limits. This leaves the agent without sufficient transparency for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
