Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'create' implies a write operation, the description doesn't address permissions needed, whether this is an atomic operation, what happens on failure, or what the response contains. For a complex creation tool with nested objects, this leaves significant behavioral questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
