Overview
Run /brag inside a website or app project and your agent reads the code, picks an angle and writes a storyboard for a 15 to 25 second launch video. It hands a brief to the Hyperframes video tool, which builds and renders the video with bundled music and sound effects. You get a brag-output folder with the plan, the finished brag.mp4, a poster image and share copy. It suits makers who just built something and want a post-ready video.
It works from your project's own code, so it needs no live link or screenshots, and you can steer the tone with presets or a line of direction.

What you get
From the creator's documentation.
| Output | What it is | Reads |
|---|---|---|
| Project reading | Reads your project code to find the product angle, copy and key screens | Your project files |
| Storyboard | A brag-plan.md with the hook, scenes, timing and sound cues | Your project files |
| Tone presets | Seven presets such as polished, chaotic and cinematic, or your own direction | Your project files |
| Rendered video | brag.mp4 in landscape, vertical or square, with bundled music and sound effects | Hyperframes CLI |
| Share copy | A share-copy.txt and a poster image for your post | Your project files |
Good to know
Make a short video to announce a site or app you just built. The skill reads the project code, plans a storyboard and a hook, and renders the video through Hyperframes, with share copy for your post.
Limits
- Rendering needs Node.js 22 or newer, FFmpeg and the Hyperframes CLI on your computer; run npx hyperframes doctor to check them.
- Voiceover is off unless you ask for it with --voice. Check the on-screen claims and share copy against your product before posting.
- On Claude Opus 5.5 it switches to a lighter workflow without Hyperframes; add --full to keep the Hyperframes one.
