  Paperclip UI design system guide for building consistent, reusable frontend
  components. Use when creating new UI components, modifying existing ones,
  adding pages or features to the frontend, styling UI elements, or when you
  need to understand the design language and conventions. Covers: component
  creation, design tokens, typography, status/priority systems, composition
  patterns, and the /design-guide showcase page. Always use this skill
  alongside the frontend-design skill (for visual quality) and the
  web-design-guidelines skill (for web best practices).

# Paperclip Design Guide

Paperclip'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 |

### Radius

Single `--radius` variable (0.625rem) with derived sizes:

- `rounded-sm` — small inputs, pills
- `rounded-md` — buttons, inputs, small components
- `rounded-lg` — cards, dialogs
- `rounded-xl` — card containers, large components
- `rounded-full` — badges, avatars, status dots

### Shadows

Minimal shadows: `shadow-xs` (outline buttons), `shadow-sm` (cards). No heavy shadows.

---

## 4. Typography Scale

Use these exact patterns — do not invent new ones:

| Pattern | Classes | Usage |
|---------|---------|-------|
| Page title | `text-xl font-bold` | Top of pages |
| Section title | `text-lg font-semibold` | Major sections |
| Section heading | `text-sm font-semibold text-muted-foreground uppercase tracking-wide` | Section headers in design guide, sidebar |
| Card title | `text-sm font-medium` or `text-sm font-semibold` | Card headers, list item titles |
| Body | `text-sm` | Default body text |
| Muted | `text-sm text-muted-foreground` | Descriptions, secondary text |
| Tiny label | `text-xs text-muted-foreground` | Metadata, timestamps, property labels |
| Mono identifier | `text-xs font-mono text-muted-foreground` | Issue keys (PAP-001), CSS vars |
| Large stat | `text-2xl font-bold` | Dashboard metric values |
| Code/log | `font-mono text-xs` | Log output, code snippets |

---

## 5. Status & Priority Systems

### Status Colors (consistent across all entities)

Defined in `StatusBadge.tsx` and `StatusIcon.tsx`:

| Status | Color | Entity types |
|--------|-------|-------------|
| active, achieved, completed, succeeded, approved, done | Green shades | Agents, goals, issues, approvals |
| running | Cyan | Agents |
| paused | Orange | Agents |
| idle, pending | Yellow | Agents, approvals |
| failed, error, rejected, blocked | Red shades | Runs, agents, approvals, issues |
| archived, planned, backlog, cancelled | Neutral gray | Various |
| todo | Blue | Issues |
| in_progress | Indigo | Issues |
| in_review | Violet | Issues |

### Priority Icons

Defined in `PriorityIcon.tsx`: critical (red/AlertTriangle), high (orange/ArrowUp), medium (yellow/Minus), low (blue/ArrowDown).

### Agent Status Dots

Inline colored dots: running (cyan, animate-pulse), active (green), paused (yellow), error (red), offline (neutral).

## 6. Component Hierarchy

Three tiers:

1. **shadcn/ui primitives** (`ui/src/components/ui/`) — Button, Card, Input, Badge, Dialog, Tabs, etc. Do not modify these directly; extend via composition.
2. **Custom composites** (`ui/src/components/`) — StatusBadge, EntityRow, MetricCard, etc. These capture Paperclip-specific design language.
3. **Page components** (`ui/src/pages/`) — Compose primitives and composites into full views.

**See [references/component-index.md](references/component-index.md) for the complete component inventory with usage guidance.**

### When to Create a New Component

Create a reusable component when:
- The same visual pattern appears in 2+ places
- The pattern has interactive behavior (status changing, inline editing)
- The pattern encodes domain logic (status colors, priority icons)

Do NOT create a component for:
- One-off layouts specific to a single page
- Si
