Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already convey that this is not read-only, not idempotent, and not destructive; the description adds that the run draws on eligible captures from organization executives/owners, which is useful scoping. It does not disclose side effects, return value, or async behavior, but the annotation set lowers the burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
