Brag: A Claude Code Skill That Films Your Launch Video
Brag is an open Claude Code skill that turns a finished build into a short launch video with music and share copy, one command.
The team at latent-spaces built /brag as a Claude Code skill: one command turns a finished project into a short launch video, with music, motion and ready share copy included. The classic /brag hands the brief to an outside service, Hyperframes by HeyGen, which builds and renders the video. The newer /brag-slim, made for Opus 5.5, skips that: the agent writes the script, style and animation itself, and plain ffmpeg renders the file on your own machine. It installs as a skill or a marketplace plugin in Claude Code, and the same skill format works in Codex CLI, opencode, Cursor, Copilot and Gemini CLI. The project is MIT-licensed, has 7 contributors and almost 10,000 stars three months in, and it is still active — /brag-slim was added only for the recent Opus 5.5 release. The output is a brag-output folder with the plan, a composition brief, share copy and the rendered brag.mp4.
Why a vibe-coder should care
If you build sites and apps with an agent, there is usually nothing to show for it besides a screen recording, and cutting your own launch video is a separate skill most people do not have. /brag removes that step: one command gets you a video with music and post copy, ready to share. With /brag-slim you get this without paying for an outside video service — just the agent and ffmpeg on your own laptop.
How to install
Copy this and send it to your agent — Claude Code, Codex, any of them:
Install the /brag skill (the brag-slim variant, no Hyperframes) from https://github.com/latent-spaces/brag in Claude Code, run it on my latest project, and show me the finished video from brag-output/brag.mp4.
Runs on a regular laptop — just Node.js 22+ and FFmpeg, no GPU needed.
