Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds that it returns 'all' pipelines and includes stages, which is useful. However, it does not explain behavior when the optional locationId is omitted, nor does it mention pagination or return format—gaps that annotations don't fill.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
