Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations supplied, the description bears the full burden, and it does reveal one useful behavioral fact: the tool ships a prompt kit with step-by-step instructions rather than performing analysis itself. However, it says nothing about what calling it with a query actually returns, whether output is deterministic, or how the '30-day support promise' is relevant to an API invocation, which is marketing noise rather than behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
