motion-frames

motion-frames is a skill for Claude Code, Codex from sanqiufong/slides-from-anything. It costs 91 tokens per session (943 once invoked), scanned A, a copy of motion-frames, Apache-2.0.

A recipe for creating a single 16:9 animated hero composition using HTML, CSS, and inline SVG. The result is designed as a looping visual that can be exported as video or animation.

In plain words
What is it for?
Use it to build animated landing-page heroes with rotating rings, globe or typographic marks, moving labels, timers, and parallax elements.
Why use it?
It provides a defined layer structure and animation approach for motion-focused hero sections instead of leaving the composition and timing open-ended.

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

motion-frames 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 9d 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.

Motion Frames Skill

Produce a single full-bleed motion composition. Inline CSS animations only — the page is the loop. Treat it as a poster frame that an exporter (HyperFrames, Lottie, etc.) can capture into a video.

Workflow

  1. Read the active DESIGN.md (injected above). Motion lives or dies on typography contrast — pick the most expressive serif / display token in the DS for the headline; the body / mono token labels everything else.
  2. Compose the canvas as a 16:9 hero with these layers, back to front:
    • Stage — full-bleed <main>. Off-white or DS-canvas background, very subtle dotted grid texture (CSS background, radial-gradient dots at 22–32px intervals).
    • Concentric rings — 2–3 SVG circles radiating from a focal point. Ultra-thin strokes (0.5–1px) in DS-foreground at low opacity. These rotate at different speeds (60s, 90s, 180s).
    • Focal mark — a wireframe globe, a stylized object, or a typographic monogram drawn as inline SVG. ~28% of the canvas wide.
    • Ring labels — short words / phonetic tokens placed around one of the rings (e.g. "Hola · Bonjour · 你好 · नमस्ते"). They co-rotate with the ring, with <text> paths counter-rotated so the words stay upright.
    • Headline — bottom-left or center-bottom. Display serif, italic accent on one word. Add a subtle letterSpacing + opacity reveal animation (@keyframes type-in).
    • Frame chrome — corner stamps (top-left lab tag, top-right brand or issue number) and a thin baseline rule. Static.
  3. Animate with @keyframes only — no JS:
    • rotate-slow, rotate-med, rotate-fast for rings.
    • globe-spin for the focal mark.
    • pulse for the focal dot, ~2s, easing.
    • marquee-fade to reveal headline once on load.
  4. Write a single HTML document:
    • <!doctype html> through </html>, CSS inline.
    • All motion uses CSS — no scripts, so HyperFrames or any frame-grabber can capture it deterministically.
    • data-od-id on stage, focal, ring, headline, chrome.
  5. Self-check:
    • The composition still reads as a poster with motion paused at frame 0.
    • At least 3 layers move at different speeds (depth comes from delta velocity, not parallax tricks).
    • Accent appears once — usually the italic word in the headline.
