Good for

  • Create a launch video from a project folder
  • Introduce a website using its actual interface
  • Produce a vertical or square launch video
  • Prepare a video and accompanying share copy

Overview

What it does

Create a launch video from the current project directory or a website URL. The skill reuses the source's actual screens, fonts, and assets. It handles the video structure, visuals, music, sound effects, audio mixing, and final rendering. The plan, finished video, and accompanying text for sharing are saved in brag-output/.

When it helps

Use it when you want a short video to introduce a project you have developed or a website you are launching. It suits presentations that show the actual interface. You can request landscape, portrait, or square video to fit the destination, and specify the tone and duration.

Example requests

  • “Create a launch video for this project.”
  • “Use this URL to make a portrait introduction video and share copy.”
  • “Make it 30 seconds long with a calm tone.”

Notes

The skill is written for Claude Opus 5.5. It has no fixed toolchain, but production assumes FFmpeg and a headless browser such as Playwright, Puppeteer, or Chrome. It uses neither Hyperframes nor bundled assets. The supplied material is a catalog description; installation retrieves the actual skill from its upstream source.

This overview was written by AI (OpenAI Codex) from the public SKILL.md. Check the original below for the exact behavior.

Objective evaluation

AI rated this skill on four points using only the contents of its SKILL.md. Stars and popularity are not taken into account.

Brag Slim (upstream-maintained)

Catalog stub. This entry is maintained upstream at latent-spaces/brag: the project ships /brag-slim as a single SKILL.md under skills/brag-slim/. hermes skills install official/creative/brag-slim pulls the current file live from that repo (quarantined and scanned like any hub install) — this directory holds only the catalog metadata, so the vendored copy can never go stale.

/brag-slim is the lean /brag, written for Claude Opus 5.5: no Hyperframes, no bundled assets. The model builds the whole launch video itself (story, visuals, music, sound effects, mix and render) with the tools already on the machine. It takes the current project directory or a website URL, reuses the source's real UI, fonts and assets instead of redrawing them, and writes brag-output/ with the plan, the rendered video and share copy. Options: --tone, --format landscape|vertical|square, --duration.

brag adds the classic Hyperframes workflow, the bundled soundtrack and SFX, and --voice narration (see its prerequisites). It includes this skill and hands off to it on Opus 5.5.

Prerequisites

  • No fixed toolchain: the model builds with whatever is installed. In practice that means FFmpeg for the audio mix and encode, plus a headless browser (Node with Playwright or Puppeteer, or Chrome) to draw frames from HTML and to capture websites that render their page with JavaScript.
