/brag: The Free Claude Code Skill That Makes Your Launch Video

Here's a pattern you might recognize. You spend three weekends building something, it finally works, and then you post a screenshot and one sentence on X because making a proper launch video feels like a whole second project. /brag exists to kill that moment. You type one command inside your project and get a short launch video back, with music, motion and the copy to post alongside it.

How it works

/brag is an agent skill, so it runs inside the coding agent you already use. When you say let's /brag, it looks at the project you're sitting in, works out what the product actually does and who it's for, and decides which moments are worth showing. That's the story part, and that's the job the skill owns.

Then it hands a focused brief to Hyperframes, HeyGen's video framework, which builds the scenes, times them to the music and renders the file. You end up with a brag-output/ folder holding the plan, the composition brief, share copy for your post, and the finished brag.mp4. The looping video on the project's own launch site was made by running /brag on its own repo, which is a nice bit of dogfooding.

You can steer the tone, too. The README's example is /brag --tone "fake Series A launch from 2016", and yes, that's exactly as cringe-perfect as it sounds. Voiceover is off by default. Add --voice if you want narration.

/brag vs /brag-slim

There are two versions now. The original uses Hyperframes plus a bundle of music and sound effects. The newer /brag-slim is a single-file skill rebuilt for Claude Opus 5.5: no Hyperframes, no bundled assets, same creative rules, and it still writes a soundtrack and share copy for your specific project. On Opus 5.5, /brag switches to the slim version on its own. Run /brag --full if you want the classic workflow back.

If you don't want to run anything locally, the authors also have a hosted version at letsbrag.app where you paste a link and get a video. The skill itself stays free and open source.

Installing it

In Claude Code it's two commands:

/plugin marketplace add latent-spaces/brag
/plugin install brag@brag

For Cursor, Codex, Copilot, Gemini CLI or opencode, the npx skills add https://github.com/latent-spaces/brag --skill brag route works across all of them. The full version needs Node.js 22+, FFmpeg on your PATH and the Hyperframes CLI (npx hyperframes doctor tells you if anything is missing). If plugin marketplaces are new to you, we wrote up how Claude skill marketplaces work and how to install skills straight from GitHub.

Who should use it

Indie hackers, side-project people, anyone doing a Product Hunt launch or a "Show HN." Also developer-tool teams who ship small features weekly and never have a designer free to cut a clip for each one. A 20 second video with motion gets noticeably more attention in a feed than a static screenshot, and it takes /brag minutes instead of an afternoon in a video editor.

It won't replace a real motion designer for your big funding announcement, and I wouldn't pretend otherwise. What it does is make "good enough to post" free. For most launches that's the gap that actually matters, because the alternative usually isn't a professional video. It's no video at all.

Why it took off

At the time of writing the repo has more than 16,000 stars on GitHub, which is a lot for a skill. I think the reason is simple. Coding agents made building fast, and the bottleneck moved to telling people about it. /brag goes after that second half. It's MIT licensed, and the bundled music and sound effects come from ende.app and Kenney, both credited in the repo.

Once the video is out, the next problem is where to post it. Our guide on mentioning your product on Reddit without getting banned is a good next read. And if you're just getting set up, start with getting started with Claude Code.
