Description
DemoKit reads your codebase, plans the demo, drives the real app in a browser, films it in 4K with Cap's camera, then checks every step three ways — and writes no file unless the feature actually worked. CLI + agent skill. AGPL-3.0. npm i -g @dekai/demokit

Could you build this?
Partial The CLI wrapper and agent prompts can be vibe coded, but deterministic headless browser control, smooth programmatic 4K camera spring-physics rendering, and multi-modal step verification require complex video pipeline engineering.
What it would actually take: The stack relies on Playwright/Puppeteer with CDP (Chrome DevTools Protocol) event capture, a custom canvas/FFmpeg video rendering pipeline executing spring-physics math for zoom and cursor movements, and an automated verification engine comparing DOM states, network traffic, and visual frame assertions. The primary complexity lies in deterministic frame-by-frame video rendering without drift, high-fidelity cursor interpolation, and robust multi-step verification before encoding.
