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 | $0.00028 | $0.03531 |
| Opus 5.5 | $0.00011 | $0.01412 |
| Sonnet 5.5 | $0.00006 | $0.00706 |
| Haiku 4.5 | $0.00003 | $0.00353 |
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 1mo 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
The opening of the file, as written. The whole thing — 442 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Design
Production-grade UI design skill combining design system thinking with bold aesthetic execution. Covers web (HTML/CSS/JS, React, Vue, etc.) and mobile (Flutter, React Native, SwiftUI, etc.).
MODE DETECTION (FIRST STEP)
Analyze the user's request to determine platform:
| Request Pattern | Mode | Focus |
|---|---|---|
| HTML, CSS, JS, React, Vue, Next.js, landing page, dashboard, web app | WEB |
Browser viewport, responsive breakpoints, CSS animations |
| Flutter, React Native, SwiftUI, Kotlin, mobile app, iOS, Android | MOBILE |
Touch targets, safe areas, platform depth, native patterns |
| Unspecified | WEB |
Default to web unless context suggests mobile |
DESIGN PROCESS (BEFORE CODING)
Before writing any code, commit to a BOLD aesthetic direction by answering four questions:
- Purpose: What problem does this interface solve? Who uses it?
- Tone: Pick a clear direction — brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian. Commit fully.
- Constraints: Technical requirements (framework, performance, accessibility)
- Differentiation: What is the ONE thing someone will remember about this interface?
CRITICAL: Choose a clear conceptual direction and execute with precision. Bold maximalism and refined minimalism both work — the key is intentionality, not intensity.
Then implement working code that is:
- Production-grade and functional
- Visually striking and memorable
- Cohesive with a clear aesthetic point-of-view
- Meticulously refined in every detail
Design-First Workflow
- Design the actual piece of functionality first — not the shell, navigation, or chrome
- Work in grayscale first — add color after hierarchy is clear
- Establish systems (spacing, type, color) before detailed design
- Details come later — work in cycles
What ships with it
3 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 anilcancakir/claude-code-plugin (2 stars, last pushed 5mo ago), licensed MIT. It adds 28 tokens to every session and 3,531 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
