Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already disclose that this is a non-read-only, non-idempotent, open-world, non-destructive operation, so the description only needs to add context. It adds that the action involves a file upload and initiates an import process, but does not explain file format expectations, whether the import is asynchronous, what happens on partial failure, or what existing data may be affected. The description is consistent with the annotations but remains shallow.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
