design-guide is a skill for Claude Code from arthurzhuhan/one-person-capital. It costs 106 tokens per session (3,021 once invoked), scanned A, a copy of design-guide, MIT.

A design guide for OnePersonCapital’s frontend, covering reusable interface components, visual styles, accessibility patterns, and common technologies.

In plain words
What is it for?
Use it when building or modifying React and TypeScript interfaces, styling pages, choosing icons, or checking layout, keyboard, and component conventions.
Why use it?
It helps new screens and components match the existing dark, information-dense interface instead of developing unrelated styles or behaviors.

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

design-guide 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.

Origin

This is a copy

98% identical to design-guide — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

OnePersonCapital Design Guide

OnePersonCapital's UI is a professional-grade control plane — dense, keyboard-driven, dark-themed by default. Every pixel earns its place.

Always use with: frontend-design (visual polish) and web-design-guidelines (web best practices).


1. Design Principles

  • Dense but scannable. Maximum information without clicks to reveal. Whitespace separates, not pads.
  • Keyboard-first. Global shortcuts (Cmd+K, C, [, ]). Power users rarely touch the mouse.
  • Contextual, not modal. Inline editing over dialog boxes. Dropdowns over page navigations.
  • Dark theme default. Neutral grays (OKLCH), not pure black. Accent colors for status/priority only. Text is the primary visual element.
  • Component-driven. Prefer reusable components that capture style conventions. Build at the right abstraction — not too granular, not too monolithic.

2. Tech Stack

  • React 19 + TypeScript + Vite
  • Tailwind CSS v4 with CSS variables (OKLCH color space)
  • shadcn/ui (new-york style, neutral base, CSS variables enabled)
  • Radix UI primitives (accessibility, focus management)
  • Lucide React icons (16px nav, 14px inline)
  • class-variance-authority (CVA) for component variants
  • clsx + tailwind-merge via cn() utility

Config: ui/components.json (aliases: @/components, @/components/ui, @/lib, @/hooks)


3. Design Tokens

All tokens defined as CSS variables in ui/src/index.css. Both light and dark themes use OKLCH.

Colors

Use semantic token names, never raw color values:

Token Usage
--background / --foreground Page background and primary text
--card / --card-foreground Card surfaces
--primary / --primary-foreground Primary actions, emphasis
--secondary / --secondary-foreground Secondary surfaces
--muted / --muted-foreground Subdued text, labels
--accent / --accent-foreground Hover states, active nav items
--destructive Destructive actions
--border All borders
--ring Focus rings
--sidebar-* Sidebar-specific variants
--chart-1 through --chart-5 Data visualization

1 file 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.

Changes

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.
