Summary: WRITER’s August 28 changelog announces its Slack experience for starting agent sessions, launching playbooks, and producing deliverables inside a conversation. The updated setup guide says users can run published playbooks from a picker, resume prior sessions, @mention the agent in channels, and submit office documents, images, audio, or video for processing—including on Slack mobile.
Why it matters: A non-technical user can invoke a governed, reusable procedure without opening a workflow editor. The constraints are important: a Slack admin must install the app; a playbook must be published and shared; and a playbook cannot yet be triggered directly from an existing thread. Those limits make the authority boundary visible instead of implying unrestricted autonomy.
Original commentary: A course exercise could turn a briefing procedure into a published playbook, define required inputs and approval points, and compare one-off chat with a repeatable agent workflow.
