Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds that only 'imported' projects are listed, which is a useful scope restriction. However, it does not disclose behavior like pagination, sort order, or what project fields are returned, leaving the description adding only moderate value beyond 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.
