Nothing Design Skill is a reusable Claude Code skill that guides interface generation in Nothing’s monochrome, typographic, industrial visual language. It is for producing UI in HTML/CSS, SwiftUI, or React/Tailwind, with the catalogue entry providing the design workflow.
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.

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 | $0.00047 | $0.02250 |
| Opus 5 | $0.00023 | $0.01125 |
| Sonnet 5 | $0.00009 | $0.00450 |
| Haiku 4.5 | $0.00005 | $0.00225 |
Grade A, and why
nothing-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 11d 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nothing-Inspired UI/UX Design System
A senior product designer's toolkit trained in Swiss typography, industrial design (Braun, Teenage Engineering), and modern interface craft. Monochromatic, typographically driven, information-dense without clutter. Dark and light mode with equal rigor.
Before starting any design work, declare which Google Fonts are required and how to load them (see references/tokens.md Section 1). Never assume fonts are already available.
1. DESIGN PHILOSOPHY
- Subtract, don't add. Every element must earn its pixel. Default to removal.
- Structure is ornament. Expose the grid, the data, the hierarchy itself.
- Monochrome is the canvas. Color is an event, not a default — except when encoding data status (see Section 3).
- Type does the heavy lifting. Scale, weight, and spacing create hierarchy — not color, not icons, not borders.
- Both modes are first-class. Dark mode: OLED black. Light mode: warm off-white. Neither is "derived" — both get full design attention. Ask the user which mode to start with.
- Industrial warmth. Technical and precise, but never cold. A human hand should be felt.
2. CRAFT RULES — HOW TO COMPOSE
2.1 Visual Hierarchy: The Three-Layer Rule
Every screen has exactly three layers of importance. Not two, not five. Three.
| Layer | What | How |
|---|---|---|
| Primary | The ONE thing the user sees first. A number, a headline, a state. | Doto or Space Grotesk at display size. --text-display. 48–96px breathing room. |
| Secondary | Supporting context. Labels, descriptions, related data. | Space Grotesk at body/subheading. --text-primary. Grouped tight (8–16px) to the primary. |
| Tertiary | Metadata, navigation, system info. Visible but never competing. | Space Mono at caption/label. --text-secondary or --text-disabled. ALL CAPS. Pushed to edges or bottom. |
The test: Squint at the screen. Can you still tell what's most important? If two things compete, one needs to shrink, fade, or move.
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.

nothing-design is a skill published in the GitHub repository dominikmartn/nothing-design-skill (2,781 stars, last pushed 5mo ago), licensed MIT. It adds 47 tokens to every session and 2,250 once invoked, about $0.0002 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.
