We taught Claude Code to make videos. Entirely in the terminal. Now we're making hundreds of ads every week and no one in our team has downloaded CapCut or any other video editing tool. To do this we had to build a harness. Here's what's in it. We think about the video generation harness in layers: - Skills for the atoms — research a brand, generate product shots, music, voiceover, stitch clips, add captions, watch a video and critique it, etc. - Molecules that chain those atoms into specific steps and templates - A HOW_TO doc for each video we've made before, so the agent isn't starting from scratch each time. - Learnings from each video that improve the harness. There's still a human in the loop, but the human requirement is getting thinner quickly, especially for formats we've made before. Still figuring out the right structure for some of this — there are a lot of ways to improve this, especially the watch and review loop. But the core works. We're setting up creative engines that can make hundreds of ads every week with this system and get stronger with every video. See our ad library linked below for examples.
