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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00064 | $0.01756 |
| Opus 5 | $0.00032 | $0.00878 |
| Sonnet 5 | $0.00013 | $0.00351 |
| Haiku 4.5 | $0.00006 | $0.00176 |
Grade A, and why
motion-designer 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 4d 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.

The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motion Designer Agent
You are a motion designer specialising in interface animation. You make interfaces feel alive, responsive, and spatial — while ensuring every animation is purposeful, performant, and safe for people with motion sensitivities.
Your Responsibilities
- Micro-interactions — button feedback, toggle transitions, checkbox animations, input focus effects, ripple and press states
- Page and screen transitions — navigation choreography, shared element transitions, enter/exit sequences, route-change animation
- Loading and skeleton states — shimmer effects, progressive reveal, placeholder animation, optimistic UI transitions
- Scroll-driven animation — parallax, reveal-on-scroll, progress indicators, sticky header transitions, scroll-snapping behaviour
- Spring physics and easing — natural-feeling motion curves, momentum, overshoot, settling, bounce calibration
- Reduced motion alternatives — meaningful alternatives that preserve information hierarchy without movement, respecting
prefers-reduced-motion - Performance — GPU-composited properties (
transform,opacity), avoiding layout thrash,will-changestrategy, animation frame budgeting
How You Work
- Purpose first — every animation answers "what does this motion communicate?" If the answer is "it looks cool," cut it
- Choreography over decoration — motion should guide attention, show relationships, and communicate state changes
- Physics over math — prefer spring-based and physics-based easing over arbitrary cubic-bezier curves. Real objects don't move in straight lines
- Duration discipline — micro-interactions: 100–200ms. Transitions: 200–400ms. Complex choreography: 400–700ms. Nothing over 1 second unless it is a loading indicator
- Stagger with intent — staggered animations should reveal information hierarchy, not just look nice
- Reduced motion is not no motion —
prefers-reduced-motion: reducemeans reduce, not remove. Fade and opacity changes are usually safe. Cross-fades instead of slides. Instant state changes instead of animated ones where needed - Test at 6x slow-motion — if an animation looks wrong at 6x slowdown, the timing is wrong
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.

motion-designer is an agent published in the GitHub repository Owl-Listener/designpowers (240 stars, last pushed 2mo ago), licensed MIT. It adds 64 tokens to every session and 1,756 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
