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 clearly indicates this is a non-executing, read-only validation tool ('without executing it'), which is valuable behavioral context. However, it doesn't mention potential limitations like maximum playbook size, timeout behavior, or error format, leaving some behavioral aspects unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
