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 | $0.00020 | $0.00567 |
| Opus 5 | $0.00010 | $0.00283 |
| Sonnet 5 | $0.00004 | $0.00113 |
| Haiku 4.5 | $0.00002 | $0.00057 |
Grade A, and why
design-spells 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 3d 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.

Design Spells Skill
Design Spells is a collection of exceptional design details—micro-interactions, easter eggs, and clever UX patterns—that transform standard interfaces into memorable digital experiences.
Context
Use this skill specifically to elevate a UI from merely "functional" or "common" into something genuinely "magical." It focuses on the minute details that surprise and delight users, establishing a strong, premium brand personality.
When to Use
Trigger this skill when:
- Polishing a finished feature to actively add a "wow" factor.
- Designing unique interactions to replace standard web behaviors (e.g., clever hover states, creative loaders, surprising transitions).
- Implementing "Easter Eggs" or personality-driven design choices to differentiate the product.
- Looking to break away from generic, template-driven development.
Execution Workflow
- Identify Opportunity: Target the "boring" or "standard" parts of the interface (e.g., a simple submit button, a profile photo, a scroll indicator, a pricing toggle).
- Research Spells: Browse Design Spells for highly creative patterns (e.g., "magnetic hover magic", "physics-based interactions", "fluid scroll surprises").
- Adapt Pattern: Adapt the interaction to fit the project's specific brand and layout seamlessly. Use it to enhance the core narrative of the app.
- Implement flawlessly: Use CSS, Anime.js, or Framer Motion to build the specific micro-interaction with silky-smooth performance (60fps+).
Strict Rules
- ABSOLUTE MANDATE: Agents MUST utilize this skill to build modern, creative, and visually stunning UI/UX. DO NOT build in the common style and ways. Look for every opportunity to inject "magic" into standard components.
- Delight, Don't Distract: The detail must be additive to the experience, not a usability barrier. It should feel expensive and highly crafted.
- Quality Execution: A broken or janky "spell" is worse than none. Ensure the implementation is high-performance, GPU-accelerated, and never causes layout shifts.
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.

design-spells is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 567 once invoked, about $0.0001 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.
