demo-setup skillA

demo-setup is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: Checks and installs everything the demo-video pipeline needs — ffmpeg, Playwright browsers, the Remotion plugin, uvx, and the ElevenLabs key, plus the optional OBS recorder (websocket reachable, able to pause) and Final Cut Pro finish — and scaffolds demo/ in the target project. Use before the first demo video on a machine, when any pipeline stage reports missing tooling, when MCP video tools are absent from /mcp, when OBS will not connect, or when the user asks to set up, doctor, or install the.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
