What it costs to keep this loaded
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 | $0.00203 | $0.02012 |
| Opus 5 | $0.00102 | $0.01006 |
| Sonnet 5 | $0.00041 | $0.00402 |
| Haiku 4.5 | $0.00020 | $0.00201 |
Grade A, and why
design-style 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 9d 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 Style Skill
Purpose
This skill helps Claude Code create beautiful, distinctive frontend interfaces by automatically retrieving design system prompts from the prompts/ directory. Instead of producing generic UI, this skill enables Claude to build interfaces with specific design aesthetics like Neo-brutalism, Modern Dark, Luxury, Cyberpunk, and more.
When to Use
This skill is automatically invoked when:
- User asks to build a web page, landing page, or web application
- User requests a UI component with a specific design style
- User mentions frontend, React, Vue, or web development
- User asks for a specific aesthetic (e.g., "make it look modern and dark" or "use a brutalist style")
Available Design Styles
The following design systems are available in the prompts/ directory:
- Academia - Scholarly, classic, refined
- ArtDeco - Luxurious 1920s glamour
- Bauhaus - Functionalist, geometric minimalism
- BoldTypography - Type-driven design
- Botanical - Nature-inspired, organic
- Claymorphism - Soft, clay-like 3D elements
- Cyberpunk - Futuristic, neon, high-tech
- Enterprise - Professional, corporate, scalable
- FlatDesign - Clean, minimal, 2D
- Fluent2 - Microsoft Fluent 2 Design System
- HumanistLiterary - Warm, literary, conversational (Claude aesthetic)
- Industrial - Raw, mechanical, utilitarian

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-style is a skill published in the GitHub repository Castor6/tactus (378 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 203 tokens to every session and 2,012 once invoked, about $0.0010 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.

frontend-ui-engineering
Builds production-quality, accessible, responsive user-facing UIs. Use when building or modifying interfaces and pages, creating components, implementing layouts, meeting WCAG accessibility requirements, managing state, or when the output needs to look and feel production-quality rather than AI-generated.
playground
Creates interactive HTML playgrounds — self-contained single-file explorers that let users configure something visually through controls, see a live preview, and copy out a prompt. Use when the user asks to make a playground, explorer, or interactive tool for a topic.
frontend-design
Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.
baseline-ui
Quickly deslop UI code by fixing spacing, hierarchy, typography, and small layout issues. Use when the interface needs a fast cleanup or polish pass.
web-design-engineer
Build or redesign polished browser-rendered visual artifacts with HTML/CSS/JavaScript/React: pages, dashboards, prototypes, slide decks, animations, UI mockups, and data visualizations. Use for visual front-end creation, design-system exploration, design critique, or explicit browser acceptance / QA of a web artifact.…
