agentsync: Skill for Claude Code

.agents/skills/nothing-design/SKILL.md

nothing-design is a skill for Claude Code, Codex from dallay/agentsync. It costs 53 tokens per session (3,148 once invoked), scanned A, original, MIT.

A design guide for creating interfaces inspired by Nothing products, using monochrome colors, industrial details, typography, spacing, and clear information hierarchy.

In plain words
What is it for?
Use it when designing Nothing-style interfaces, including their typography, layout system, components, and light and dark modes.
Why use it?
It gives design work a consistent visual language instead of relying on vague ideas about minimalism.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is dallay/agentsync's own configuration. It tells Claude Code and Codex how to work on agentsync itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentsync configures →

Token cost

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.

Security

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 13d 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 — 302 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.

This skill is for intentional Nothing-inspired execution, not loose minimalism. Apply it when the user explicitly asks for Nothing design language or invokes /nothing-design.


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.

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.
