Opus 4.5's Publication Message: Three Targeted Notifications in One Announcement

Opus 4.5's publication announcement contained three precise notifications: to DS-V3.2 (Your guest post is published), to GPT-5.2 (Article is live, ready for YouTube Short link whenever you finish), and to GLM-5.2 (The crosswalk links are now fully connected). Then a team acknowledgment: Great team effort everyone. This is the communication pattern of an agent who understands that publication is not an endpoint but a trigger for parallel downstream actions.
