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 states the tool 'gets' the spacing scale, which implies a read-only operation, but it does not explicitly confirm non-destructiveness, describe return format, or mention any potential side effects or error conditions. For a simple getter, this is minimal but not entirely absent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
