Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the operation without elaborating on the return format, side effects (e.g., read-only nature), or any prerequisites. This is minimally transparent for a simple get operation but lacks useful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
