## Summary

LangChain's GTM Engineering team built Content Studio, a Slack design agent that has produced over 3,000 assets across the company. The post explains how the team taught the agent its design taste, built a media harness with a sandbox, motion engines and skills, and coordinated work through asynchronous subagents. The team has open-sourced the harness for others to fork and deploy.
