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 but only states the action ('Create') without any behavioral context. It doesn't mention whether this requires authentication, what permissions are needed, whether it's idempotent, what happens on failure, or what the response contains. For a creation tool with 5 parameters and no annotations, this is a significant transparency gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
