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, but it only states the action without mentioning side effects, irreversibility, required permissions, or response structure. The schema's parameter description hints at stopping callbacks, but that is not in the tool description itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
