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.

SkillSpector: 14 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.03087 |
| Opus 5 | $0.00036 | $0.01543 |
| Sonnet 5 | $0.00015 | $0.00617 |
| Haiku 4.5 | $0.00007 | $0.00309 |
Grade A, and why
emil-design-skills 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

Why These Skills Exist
"Agents don't have great taste."
Emil built these skills because AI agents consistently pick wrong animation ingredients — ease-in for enter animations (should be ease-out), solid borders instead of semi-transparent shadows, wrong timing curves. These skills encode his years of experience at Vercel and Linear into actionable rules any agent can follow.
This is domain expertise as code. AI doesn't replace taste — it amplifies it when the taste is encoded.
When to Use
Trigger phrases:
- "improve the animations in this project"
- "audit the UI motion"
- "what library should I use for X?"
- "design this UI with Apple-level polish"
- "review these animation changes"
- "help me pick between animation approaches"
- "prototype this UI component in multiple ways"
Use when:
- Building UI that needs to feel polished, not just functional
- Reviewing animation/motion PRs
- Choosing frontend libraries for a new project
- Designing gesture-driven or spring-based interactions
- Looking for where motion adds value (and where it doesn't)
- You want your agent to build interfaces that stand out from AI slop
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.

emil-design-skills is a skill published in the GitHub repository oyi77/1ai-skills (12 stars, last pushed today), licensed MIT. It adds 73 tokens to every session and 3,087 once invoked, about $0.0004 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 2026-09-03.
Other skills, from other repositories
animate
Build a web animation: whether it should animate at all, the purpose, the tool, the properties, the easing curve, the duration, interruption and exit. Writes the CSS or Motion code for dropdowns, modals, toasts, tooltips, accordions, press feedback, stagger and scroll reveals. Use to animate something or make a…
motion-craft
Use when an interface moves and the movement has to feel right — durations and easing, what must never animate, fixing motion that reads sluggish, cheap or janky, and reduced-motion. Web and native. NOT the visual system (that is design), NOT the graded critique (that is design-loop).
baseline-ui
Skill "baseline-ui" from humanerd-drew/opencode-drewgent, covering baseline ui, when to apply, rule categories by priority, 1. stack defaults and 2. html semantics.

Motion tokens, spring presets, performance rules, device adaptation, accessibility enforcement, and SSR safety for React / Next.js using motion/react.
