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 | $0.00031 | $0.01259 |
| Opus 5.5 | $0.00012 | $0.00504 |
| Sonnet 5.5 | $0.00006 | $0.00252 |
| Haiku 4.5 | $0.00003 | $0.00126 |
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 2mo 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 Skill
Purpose: Create production-grade, distinctive UI that stands out from generic AI-generated designs
Quick Start
When to Use
- Building web UI components, pages, or applications
- Creating dashboard interfaces, landing pages, or marketing sites
- Styling React components, HTML/CSS layouts, or design systems
Quick Reference
| Category | Key Principle | Action |
|---|---|---|
| Fonts | Avoid defaults | Never use Inter as default |
| Colors | Avoid gradients | No purple-to-blue gradients |
| Layout | Embrace asymmetry | Break from rigid grids |
| Details | Add texture | Use noise, patterns, borders |
Core Principles
1. Choose an Aesthetic Direction
| Direction | Characteristics | Examples |
|---|---|---|
| Minimalist | Clean, sparse, purposeful | Stripe, Linear |
| Maximalist | Bold, expressive, layered | Brutalist sites |
| Warm/Human | Organic textures, soft edges | Notion, Gumroad |
| Technical/Precise | Sharp edges, monospace | Vercel, GitHub |
| Playful | Bright colors, rounded | Discord, Slack |
Action: Start with "I'll use a [direction] aesthetic for this."
2. Make Every Detail Intentional
- Default fonts → Never accept Inter as the default
- Gradients → Purple-to-blue is the most overused gradient
- Center alignment → Explore asymmetry and interesting layouts
- Flat colors → Add texture, noise, patterns, or subtle borders
3. Be Specific, Not Generic
Bad: "Use a nice color scheme" | Good: "Use a warm palette with coral (#FF6B6B) as primary, cream (#FFF8F0) background"
Typography & Color
Font Selection
⚠️ NEVER use Inter as the default font
| Category | Font Families | When to Use |
|---|---|---|
| Serif | GT Super, Charter, Georgia | Editorial, premium |
| Sans-Serif | Geist, Satoshi, System UI | Clean, modern (not Inter!) |
| Monospace | Geist Mono, JetBrains Mono | Technical, code |
| Display | Clash Display, Syne | Headlines, personality |
What ships with it
4 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 changoo89/claude-pilot (20 stars, last pushed 8mo ago), licensed MIT. It adds 31 tokens to every session and 1,259 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 2026-08-30.
