ds-animate

A design-focused tool for adding small animations to existing website interactions, such as buttons, page changes, loading states, and elements entering the screen.

In plain words
What is it for?
Use it to animate buttons, page transitions, loading feedback, or entrance effects while matching the site's intended visual style.
Why use it?
It addresses interfaces that feel static or stiff by making existing responses and transitions clearer and more natural.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ds-animate 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble

"../lib/env.sh" "animate"

What this skill does

Right now your site probably feels a little flat or stiff. Motion fixes that. I add small, purposeful animations to existing interactions — buttons that respond when you click them, pages that transition smoothly, loading states that feel fast instead of frozen.

"Tell me what feels too static — buttons? Page transitions? Everything? I'll add motion that feels natural, not over-the-top."

Dstack's approach to animation: less is more. Every animation should have a reason. We never animate just to animate.

This skill is for interaction motion. If the user wants to improve first-success or empty-state emotion, route them to /ds-delight.

Step 1 — Load Design Bible vibe

If DESIGN_BIBLE is yes, follow the standard extraction protocol in lib/bible-reader.md. Focus on the "The feeling" section.

Let the vibe words guide animation style:

  • "calm, focused, minimal" → very subtle animations, longer durations (300–400ms), ease-out only
  • "bold, energetic, playful" → more expressive animations, spring physics, bouncy easing
  • "warm, approachable" → gentle fades, soft movements, nothing too mechanical
  • "professional, trustworthy" → barely-there animations, functional only (not decorative)

If no Design Bible: default to subtle and purposeful.

Step 2 — Understand what the user wants to animate

Ask:

"What feels too static right now? Pick the things that bother you most:

A) Buttons — they click but nothing happens visually B) Page transitions — jumping from page to page feels abrupt C) Loading states — the page just sits there while things load D) Elements appearing — content just pops in instead of flowing in E) Forms — filling in fields feels mechanical F) Something specific — I'll describe it G) Multiple interactions across the UI — give the interface a more consistent motion system"

If G: prioritize in this order — page load/appearance, button interactions, transitions, loading states.

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.
