Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations supplied, the description carries the full behavioral burden, and it instead describes product packaging ("ships as a full prompt kit with step-by-step instructions and a 30-day support promise"). It never states what the tool actually does at runtime, whether it is a read or write operation, what it returns, or what happens with an empty query. The commercial language is not merely uninformative but potentially misleading about the tool's real behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
