Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.00448 |
| Opus 5.5 | $0.00028 | $0.00179 |
| Sonnet 5.5 | $0.00014 | $0.00090 |
| Haiku 4.5 | $0.00007 | $0.00045 |
Grade A, and why
demo-animation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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.htmlfile 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-v2instead.
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.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

demo-animation is a skill published in the GitHub repository jqaisystems/jqai-ai-skills (3 stars, last pushed 13d ago), licensed MIT. It adds 71 tokens to every session and 448 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

reins
Drive the user's real, logged-in browser from the shell via the reins CLI. Because it's their actual browser, every site is already authenticated — so you can scrape behind logins, read cookies/tokens/localStorage, watch and replay live API traffic, call a site's own API as the signed-in user, and…
