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 | $0.00021 | $0.04925 |
| Opus 5 | $0.00010 | $0.02462 |
| Sonnet 5 | $0.00004 | $0.00985 |
| Haiku 4.5 | $0.00002 | $0.00492 |
Grade A, and why
frontend-design-svelte 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 6d 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.

Frontend Design Svelte Skill
Purpose
This skill guides the creation of distinctive, production-grade Svelte frontends that combine Svelte's reactive elegance with exceptional design quality. It integrates all design frameworks: intentional thinking, typography, color, motion, spatial composition, and anti-pattern awareness.
When to Use
- Building production Svelte/SvelteKit frontends
- Creating component libraries with design personality
- Designing interactions that leverage Svelte's reactivity
- Building accessible, mobile-first web applications
- Prototyping high-fidelity designs in code
Core Principles
1. Design Thinking Foundation (Pre-Coding)
Before writing any code, establish intentional design direction:
The Four Critical Questions:
- Purpose: What problem are we solving? Who are we solving it for?
- Tone: What emotional response do we want? What aesthetic direction reflects this?
- Constraints: What are the real technical, temporal, or business limits?
- Differentiation: What one unforgettable element makes this distinctly ours?
2. Anti-Generic AI Design Standards
Deliberately reject these patterns:
Typography:
- ❌ Avoid: Inter, Roboto, Open Sans as primary choices
- ✅ Prefer: Playfair Display, Crimson Pro, Space Grotesk, IBM Plex, Bricolage Grotesque
- ✅ Use high-contrast pairings: Display + Mono, Serif + Geometric Sans
- ✅ Use size jumps of 3x+, not incremental 1.5x scaling
Color & Theme:
- ❌ Avoid: Material Design trinity (blue, red, green)
- ❌ Avoid: Default SaaS blue (#0099ff) everywhere
- ✅ Prefer: Intentional palettes with one unexpected accent
- ✅ Prefer: Warm or cool personality, never neutral grays
Layout & Space:
- ❌ Avoid: Centered, symmetrical "cookie-cutter" layouts
- ✅ Prefer: Asymmetrical compositions with intentional whitespace
- ✅ Use consistent spacing scale: 8px, 12px, 16px, 24px, 32px, 48px, 64px
Motion:
- ❌ Avoid: Linear timing, instantaneous interactions
- ✅ Prefer: Orchestrated animations with easing functions
- ✅ Prefer: Staggered reveals, delightful hover surprises
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

frontend-design-svelte is a skill published in the GitHub repository matteocervelli/llms (25 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 4,925 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.
