Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already convey that this is a mutating, non-idempotent operation, and the description adds that it creates a brand-new artifact with optional slides. It does not disclose permissions, side effects, or what happens on validation failure, but the high schema coverage and output schema reduce the burden; nothing contradicts the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
