Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states it creates meetings without disclosing behavioral traits. It doesn't mention authentication requirements, rate limits, error handling, whether it's idempotent, what happens on partial failures, or the response format. 'Create' implies mutation, but no safety or side effect information is given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
