Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description alone must disclose behavior. It reveals that the operation bypasses the cache, but does not explain side effects such as overwriting existing data, whether auth is required, or whether the refresh can fail. The mutating nature is hinted but not elaborated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
