Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false and destructiveHint=false, meaning it mutates state but is not destructive. The description confirms it creates ('Save a new...'), but does not elaborate on permissions, side effects, or whether it overwrites existing configurations. Given annotations are present, a score of 3 is appropriate as the description adds minimal context beyond confirming it is a write operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
