Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already establish that this is a non-read-only but non-destructive operation, and the description adds useful behavioral context: it is triggered only by a user tapping the panel's offer or Not now. It does not elaborate on persistence or side effects beyond enabling reminders or stopping the offer, but that is reasonable given the annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
