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 | $0.00079 | $0.00548 |
| Opus 5.5 | $0.00032 | $0.00219 |
| Sonnet 5.5 | $0.00016 | $0.00110 |
| Haiku 4.5 | $0.00008 | $0.00055 |
Grade A, and why
site-motion-excellence-director 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.

Site Motion Excellence Director
Use this skill before adding substantial motion to a website or app.
Workflow
- Identify the brand, route, audience, and first user task.
- Define the first read before animation.
- Name the motion job: orient, reveal, explain, confirm, compare, express brand, or convert.
- Pass the still-frame gate.
- Write a beat sequence: setup, trigger, primary move, secondary support, hold, final state.
- Choose the lightest runtime that preserves the intent.
- Specify reduced motion in the same pass.
- Implement only after the spec is clear.
- Verify with browser screenshots, mobile, reduced motion, and video/frame proof.
- Score with the excellence gate.
Runtime Rules
- Use CSS for simple state changes, hover/focus, skeletons, and low-risk reveals.
- Use Motion for React for component choreography, layout transitions, presence, and React scroll work.
- Use GSAP ScrollTrigger for pinned, scrubbed, snapped, SVG/canvas, or complex authored timelines.
- Use Rive for interactive vector state machines.
- Use Lottie/dotLottie for portable non-interactive vector loops.
- Use Three.js only when 3D is central and visually verified.
- Use Remotion for rendered video, social variants, product explainers, and exact text/layout in media.
- Use Grok/imagegen/Veo/Sora/Luma/Runway/Higgsfield only as source generation, then finish and QA in context.
Taste Rules
- Motion is hierarchy over time.
- Do not animate a weak still frame.
- Make one object the hero.
- Use stillness as contrast.
- Keep repeated task motion short and quiet.
- Do not bake exact product text into generated images or videos.
- Treat mobile as separate choreography.
- Never ship meaningful motion without reduced-motion behavior.
Required Spec
Use templates/site-motion/SITE_MOTION_SPEC.md for substantial site motion.
Use rubrics/site-motion-excellence-gate.md before handoff.
Output Shape
Return: motion thesis, first-read diagnosis, still-frame verdict, motion map, runtime choice, reduced-motion plan, implementation tasks, QA proof required, and excellence score.
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.

site-motion-excellence-director is a skill published in the GitHub repository frankxai/awesome-motion-design-agent-skills (86 stars, last pushed 3d ago), licensed CC0-1.0. It adds 79 tokens to every session and 548 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 2026-09-01.

frontend-ui-ux-system
A company-level guide for designing web interfaces and user experiences. It covers visual styles, design tokens (named values for colors, spacing, and typography), layout, interaction, accessibility, motion, and review checks.
gradient-text
Give one short headline quiet premium emphasis: a slow on-brand gradient drifts through the type. One phrase per view; never body copy (readability). Pure CSS; falls back to a solid brand color under prefers-reduced-motion.
magnetic-button
Make a primary button feel alive by gently pulling it toward the cursor as it approaches, then springing back. Keep it subtle and reserve it for one or two primary actions. Disabled on touch and under prefers-reduced-motion. Do not use it on dense UIs full of buttons.
ripple-press
Acknowledge a tap/click with a ripple that blooms from the exact press point. Fast and low-opacity so it reads as feedback, not decoration. No ripple under prefers-reduced-motion (native :active covers it). Avoid on destructive actions and text links.
scroll-reveal
Reveal content as it scrolls into view — a gentle rise + fade, once per element. Use to give a long page calm rhythm. Honors prefers-reduced-motion and supports staggering. Do not delay above-the-fold content, and keep at most a few elements animating at once.
frontend-design
Design and build production-ready frontend interfaces with design systems, responsive layouts, accessible components, and dark mode support. Use when the user requests frontend design or provides relevant inputs for this workflow.
