It looks similar to agent-video, which is also based on agent-browser: https://www.mux.com/blog/agentic-video-screen-recording
I don't think you need either, though, because agent-browser itself has a skill for this: https://github.com/vercel-labs/agent-browser/blob/main/skill...
Maybe the author would like to compare the three.
Yes agent-video is focused on high quality recording. ProofShot uses agent-browser’s recording under the hood but the value is really in everything else: error collection, server log capture, the interactive viewer with synced timeline, and the PR upload. It’s less about the video itself and more about bundling all the evidence together to generate the evidence the agent did the work.
I would prepare a table in the README with all these features as comparison points.
