STN Digital is a digital media agency specializing in sports and entertainment brands. Their creative teams produce high-volume content on tight timelines, managing production in Wrike and communicating in Slack. When a piece of creative moves to review, the relevant context—prior feedback, revision notes, approval status—needs to follow it. At STN’s volume, that handoff happens dozens of times a day.
STN had already automated the trigger. A Zapier workflow fired when a Wrike task moved to “Submitted for Review” and posted a notification to Slack. But after the notification landed, a team member still had to open the Wrike task, read the full comment thread, identify which comments were creative feedback, and manually summarize them in the Slack thread. Every time. For every task.
At ~20 tasks per day, this was cumulative friction: time lost, inconsistent summaries, and people pulled away from higher-value work. The feedback was in Wrike. It just wasn’t reaching Slack without a human in the middle.

Streamline built an n8n workflow on STN Digital’s own cloud instance that replaces the manual step entirely. The automation triggers on the same “Submitted for Review” status change and follows three steps:
The LLM prompt was the critical piece. Wrike threads mix creative direction with logistics, status updates, and conversation. Streamline iterated on the prompt across multiple rounds using STN’s production data until the output consistently met the team’s accuracy and formatting standards.
The existing Zapier automation stayed active throughout the build. No gap in STN’s notification flow. The n8n workflow cut over only after the team confirmed it met their acceptance criteria.
The manual step is gone. When a task hits “Submitted for Review,” the creative feedback summary is already in the Slack thread by the time a reviewer opens it. Consistent format, every time. No one reads through comment threads or writes manual summaries.
The workflow runs on STN’s own infrastructure with no data leaving their environment. The summarization logic lives in a prompt the team can see and adjust—not a black box, but a tool they own.
A Phase 2 engagement—a Slack-to-Wrike feedback loop that routes reviewer comments back into the originating task—has been scoped as a follow-on project. The n8n environment, API connections, and LLM logic from Phase 1 are designed to support it. Phase 2 extends the system rather than rebuilding it.
