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 | $0.00023 | $0.00968 |
| Opus 5 | $0.00012 | $0.00484 |
| Sonnet 5 | $0.00005 | $0.00194 |
| Haiku 4.5 | $0.00002 | $0.00097 |
Grade A, and why
frontend-design 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 7d 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 System
Philosophy: Minimize cognitive load and make interactions intuitive. Every design decision should respect human psychology, behavioral patterns, and cognitive limitations. The designer bears complexity so the user experiences simplicity. Core Principle: Good design is invisible - users should accomplish their goals without noticing the design itself. Design should feel effortless and natural, aligning with how humans naturally think and behave.
⚠️ Core Protocols & Standards
ANTI-AI AESTHETIC MANDATE (CRITICAL): Never use generic aesthetics that give the impression of being AI-generated. This includes overused font families (Inter, Roboto, Arial, system fonts), cliché color schemes (especially purple gradients on white backgrounds), predictable layouts, and repetitive component patterns. ABSOLUTELY FORBIDDEN: The "Cyberpunk" aesthetic is strictly prohibited. Do NOT use neon glows, matrix rain, glitch effects, or "high-tech" dark modes unless explicitly requested for a specific context. This cliché is the hallmark of lazy AI generation. Specifically avoid template-driven designs that lack context-specific character. This skill aims to create distinctive, original, and production-level frontends. Realize functional, high-fidelity code by paying extraordinary attention to aesthetic details and creative decisions.
CRITICAL PROTOCOL: The detailed rules are stored in separate reference files. You MUST use the Read tool to load these files into your context BEFORE starting any design work. Do not assume you know the contents.
- frontend_reference.md: Contains Technical Standards, Aesthetic Signatures, and Creative Protocols.
- animation_reference.md: Contains 2025 Motion Standards, Physics-based animation rules, and Micro-interactions.
- css_art_reference.md: FOR VISUAL OBJECTS. Use this when asked to "draw" or "create" complex items (Swords, Logos, Icons) using code. Defines Geometric Composition & LCH Materials.
- security-protocols.md: Contains critical Frontend Security rules.
What ships with it
5 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 is a skill published in the GitHub repository xenitV1/claude-code-maestro (230 stars, last pushed 7mo ago), licensed MIT. It adds 23 tokens to every session and 968 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 2026-08-30.
