What /brag does

/brag turns the website or project you just built into a short launch video. The main skill reads the project code directly, so no live URL or screenshots are needed, then plans a story, builds scenes from a large template set, adds music and renders through Hyperframes, HeyGen's HTML-to-video tool. There is a variant, brag-slim, which is a single file with no bundled assets: the model does the story, visuals, audio and render itself with whatever tools exist on the machine, and it can start from a project directory or a website URL. Options cover tone presets or free-form tone, and formats such as landscape, vertical and square. The repo contains roughly 280 template files, a few reference documents and one helper script, analyze_music_cues.py, for syncing cuts to music. The skills are about 9 KB each. The author also runs a hosted site, letsbrag.app, that makes the video from a pasted link without any setup. On Windows, cloning needs symlink support enabled through git config and Developer Mode.

Good for

  • Launch or demo clips for a freshly built web project
  • Developers who want shareable promo video without editing software
  • Quick social video with generated share copy

Not for

  • Long-form or heavily art-directed video production
  • Machines without a working video-rendering toolchain

What's inside depth 3/5

Two ~9 KB skills with about 280 template files, seven reference files and one helper script, but no tests or evals.

Security review

Review before installing

A skill that turns your project's site or code into a short launch video by planning a story and driving Hyperframes to render it. It reads project files (with rules to skip .env, keys and credentials), may fetch a live site, and shells out to unpinned npx hyperframes plus FFmpeg; one optional Python script analyses audio locally. Nothing in the files we read uploads data, but the Hyperframes tool that does the rendering was not reviewed.

Worth knowing

  • Runs remote code at an unpinned versionThe workflow runs npx hyperframes check, snapshot, preview and render (HeyGen's Hyperframes CLI) without a version pin to build and render the video.skills/brag/references/step-4-deliver.md:7
  • Relies on a CLI or package we could not reviewRequires the Hyperframes CLI, FFmpeg and Node.js 22+; optional voiceover (--voice) uses Kokoro through Hyperframes. None of that code is in the repository.README.md:130
  • Installs packages or toolsThe optional beat-analysis path needs librosa, numpy, scipy and soundfile (version floors only) installed with Python/uv; the skill tells the agent to ask before installing missing tools.skills/brag/scripts/pyproject.toml:6
  • Makes network requestsMay fetch a live website (loading it in a headless browser if needed) and download its images and videos as data for the video; it is told to treat fetched content as data only and to download media only, never executables.skills/brag/slim.md:43

What we checked

The repository (370 files) on Oct 29, 2026. Not a full review: 52 of 370 files were not downloaded (large repository; we reviewed the skill folders); it relies on code outside the repository: Hyperframes CLI (npx hyperframes), FFmpeg and Kokoro voice model used for rendering; 52 of 370 repository files were not available to us (plugin manifests and symlinked skill folders); 294 media files (bundled music and SFX) cannot be inspected as text.

NVIDIA SkillSpector static scan: 26 pattern hits (MCP Rug Pull 17, Supply Chain 4, Data Exfiltration 3, Agent Snooping 2). The SkillSpector hits are unpinned npx skills/npx hyperframes mentions, the ~/.gemini skills path in the README, a README link to api.star-history.com for a badge, a 'curl | sh' phrase in brag-slim that tells the agent to prefer a package manager over it, and CVE notes on the numpy/scipy version floors.

Can it run unattended?

Not really. It is a one-command creative flow with human review of the result, not a long-running loop.

FAQ

What is /brag?

/brag is an agent skill that makes a short launch video from your project, including music, motion graphics and share copy. It is powered by Hyperframes.

How do I install /brag?

For any agent, run npx skills add https://github.com/latent-spaces/brag --skill brag. Codex users can run codex plugin marketplace add latent-spaces/brag, and the repo also documents the Claude Code plugin.

What is the difference between brag and brag-slim?

brag uses a bundled template library and helper script. brag-slim is a single file with no bundled assets, where the model builds the whole video with the tools already on your machine.

Can I get a /brag video without installing anything?

Yes, the README points to letsbrag.app, where you paste a site link and get a 20-second video.
