Demo Animation
Generate a simple self-playing HTML product demo. Output: demo/index.html.
For most new demo requests, prefer demo-animation-v2. Use this skill when the user asks for the legacy desktop-oriented demo style or when a smaller, simpler demo is enough.
Workflow
- Read the project README, app entry points, and relevant UI files.
- Identify the product name, tagline, visual style, font stack, and 6-10 features to showcase.
- Draft a brief demo step list. If the project is unclear, ask one concise question; otherwise proceed.
- Generate a single self-contained
demo/index.html file with no external dependencies except Google Fonts.
- Include intro, dashboard mockup, animated cursor/highlights, sidebar captions, timeline controls, optional piano music, ending screen, and replay.
- Validate that all referenced IDs exist, controls work, and the file opens directly in a browser.
Legacy Reference
If you need the original desktop architecture, read references/legacy-demo-engine.md. It contains the older detailed CSS, layout, animation, music, and quality checklist guidance.
Rules
- Keep the generated UI realistic for the actual product.
- Keep wait times reasonable: 800-1500ms for reading, 300-600ms for animations.
- Do not add network dependencies beyond Google Fonts.
- Do not use this legacy skill when the user explicitly requests mobile-first, touch, fullscreen, or highly responsive behavior; use
demo-animation-v2 instead.
Output
Write to demo/index.html. Tell the user:
Demo created at `demo/index.html`. Open it in a browser to preview. Click "Watch Demo" to start the animation.
