## What it does

The skill runs in agents that read `SKILL.md`: Claude, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode. You describe the outcome, the agent builds a single-file HTML with a clickable prototype inside an iPhone 15 Pro or Android bezel, a slide deck, a timeline animation exported to MP4 and GIF, or a print-quality infographic. A separate mode critiques a design across five dimensions and returns a radar chart with a Keep/Fix/Quick Wins list.

The repo ships the building blocks: `animations.jsx` with Stage, Sprite, Easing and interpolate primitives, device frames, the `deck_stage.js` slide engine, the `design_canvas.jsx` variant panel, 24 prebuilt examples and six background tracks. Scripts `render-video.js`, `convert-formats.sh`, `add-music.sh` and `html2pptx.js` handle Playwright rendering, 60fps interpolation, music muxing and converting DOM styles into editable PPTX objects.

The agent does not start blind. It fires a batch of questions first, marks assumptions and placeholders inside the HTML, and shows a gray-box skeleton for approval. When a named brand is involved, the skill insists on pulling brand colors from downloaded assets into `brand-spec.md` instead of guessing from memory. Video rendering goes through Playwright, so check that it is installed before asking for an MP4.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)
