/brag

You built it. Now brag.

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

/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)

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.

Agent	How it discovers
Google Antigravity	Auto-detects from .agents/skills/brag/ at project root or ~/.gemini/config/skills/brag/ globally
opencode	Auto-detects from .opencode/skills/brag/ at project root
Codex CLI	Reads .agents/skills/brag/, walking up to repo root
Claude Code	Also reads .claude/skills/brag/ (in addition to the .claude-plugin/ marketplace install above)
Other agents	Point custom instructions at skills/brag/SKILL.md — see docs/other-agents.md

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.

Requirements

• An agent that supports Agent Skills — Claude Code, opencode, Codex CLI, or any agent with custom instructions (see "Also works with" above)
• Node.js 22+
