brag

/brag

You built it. Now brag.

Want a video without running /brag yourself? Paste your site's link at letsbrag.app.

[](https://latent-spaces.github.io/brag/)

/brag is an agent skill that turns the project you created into a short, shareable launch video — music, motion, and share copy included. One command, powered by Hyperframes.

The looping video on the launch site was made by /brag on this very repo.

Rather not run it yourself? Use letsbrag.app

letsbrag.app runs /brag for you. Paste your site's link and get a 20-second launch video with music, motion, and share copy. No setup, no subscription.

The skill stays free and open source. Install it below and run it yourself anytime.

New: /brag-slim

The same /brag, rebuilt lean for Opus 5.5.

A smooth launch video, designed for your specific project, with its own soundtrack and share copy.

No Hyperframes, no bundled assets, same creative rules.

Just tell Opus 5.5: let's /brag about this.

On Opus 5.5, /brag switches to /brag-slim automatically. Run /brag --full to keep the classic Hyperframes workflow.

Install just /brag-slim:

npx skills add https://github.com/latent-spaces/brag --skill brag-slim

Already have the Claude Code /brag plugin? /brag-slim is included from version 0.4.0. Run claude plugin update brag to get it.

Install /brag

Codex:

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

To update it later:

codex plugin marketplace upgrade brag
codex plugin add brag@brag

Claude Code:

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

Then run /brag inside any project. The plugin includes /brag-slim too.

Any other agent — one command via the skills CLI (Cursor, Codex, Copilot, Gemini CLI, opencode, and more):

npx skills add https://github.com/latent-spaces/brag --skill brag

Add -g to install globally (available in every project); drop it to scope to the current one. (browse on skills.sh)

No installer? Copy the skill directly.

rsync -a --exclude '.DS_Store' skills/brag/ ~/.claude/skills/brag/
rsync -a --exclude '.DS_Store' skills/brag-slim/ ~/.claude/skills/brag-slim/  # optional: the /brag-slim command

Restart Claude Code after copying.

Also works with

This repo exposes the skill at every agent's standard discovery path via symlinks. No extra config needed.

Windows users: Git requires git config core.symlinks true (or git clone -c core.symlinks=true) and Windows Developer Mode or Administrator privileges to create symlinks. If symlinks don't work on your system, copy skills/brag/ to the agent's skill directory manually instead.

Use it

From any project directory, ask your agent:

let's /brag

Or steer the tone:

/brag --tone "fake Series A launch from 2016"

Voiceover is off by default. Enable it explicitly with:

/brag --voice

Narration uses Kokoro through Hyperframes when enabled.

You get a brag-output/ folder with the plan, a composition brief, share copy, and the rendered brag.mp4.

How it works

/brag owns the story — the product angle, tone, and which moments to show. It hands a focused brief to Hyperframes, which builds, times, and renders the video.
