Stageshow skill teaches coding agents to build product UI demos as React components
Stageshow is a skill that agents such as Claude Code, Codex and Gemini read before making mock product interfaces and demo animations. The agent starts from the closest example, builds the demo, films it, then fixes what it finds, and the result is an ordinary React component. A playground shows the same demo done badly and done well side by side. Its author says most demos still take a few rounds of feedback.
