Baarali Design Guide

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:

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:

5. Status & Priority Systems

Status Colors (consistent across all entities)

Defined in StatusBadge.tsx and StatusIcon.tsx:

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 Baarali-specific design language.
3. Page components (ui/src/pages/) — Compose primitives and composites into full views.

See 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
• Simple className combinations (use Tailwind directly)
• Thin wrappers that add no semantic value

7. Composition Patterns

These patterns describe how components work together. They may not be their own component, but they must be used consistently across the app.

Entity Row with Status + Priority

The standard list item for issues and similar entities:

<EntityRow
  leading={<><StatusIcon status="in_progress" /><PriorityIcon priority="high" /></>}
  identifier="PAP-001"
  title="Implement authentication flow"
  subtitle="Assigned to Agent Alpha"
  trailing={<StatusBadge status="in_progress" />}
  onClick={() => {}}
/>

Leading slot always: StatusIcon first, then PriorityIcon. Trailing slot: StatusBadge or timestamp.

Grouped List

Issues grouped by status header + entity rows:

<div className="flex items-center gap-2 px-4 py-2 bg-muted/50 rounded-t-md">
  <StatusIcon status="in_progress" />
  <span className="text-sm font-medium">In Progress</span>
  <span className="text-xs text-muted-foreground ml-1">2</span>
</div>
<div className="border border-border rounded-b-md">
  <EntityRow ... />
  <EntityRow ... />
</div>

Property Row

Key-value pairs in properties panels:

<div className="flex items-center justify-between py-1.5">
  <span className="text-xs text-muted-foreground">Status</span>
  <StatusBadge status="active" />
</div>

Label is always text-xs text-muted-foreground, value on the right. Wrap in a container with space-y-1.

Metric Card Grid

Dashboard metrics in a responsive grid:

<div className="grid md:grid-cols-2 xl:grid-cols-4 gap-4">
  <MetricCard icon={Bot} value={12} label="Active Agents" description="+3 this week" />
  ...
</div>

Progress Bar (Budget)

Color by threshold: green (<60%), yellow (60-85%), red (>85%):

<div className="w-full h-2 bg-muted rounded-full overflow-hidden">
  <div className="h-full rounded-full bg-green-400" style={{ width: `${pct}%` }} />
</div>

Comment Thread

Author header (name + timestamp) then body, in bordered cards with space-y-3. Add comment textarea + button below.

Cost Table

Standard <table> with text-xs, header row with bg-accent/20, font-mono for numeric values.

Log Viewer

bg-neutral-950 rounded-lg p-3 font-mono text-xs container. Color lines by level: default (foreground), WARN (yellow-400), ERROR (red-400), SYS (blue-300). Include live indicator dot when streaming.

8. Interactive Patterns

Hover States

• Entity rows: hover:bg-accent/50
• Nav items: hover:bg-accent/50 hover:text-accent-foreground
• Active nav: bg-accent text-accent-foreground

Focus

focus-visible:ring-ring focus-visible:ring-[3px] — standard Tailwind focus-visible ring.

Disabled

disabled:opacity-50 disabled:pointer-events-none

Inline Editing

Use InlineEditor component — click text to edit, Enter saves, Escape cancels.

Popover Selectors

StatusIcon and PriorityIcon use Radix Popover for inline selection. Follow this pattern for any clickable property that opens a picker.

9. Layout System

Three-zone layout defined in Layout.tsx:

┌──────────┬──────────────────────────────┬──────────────────────┐
│ Sidebar  │  Breadcrumb bar              │                      │
│ (w-60)   ├──────────────────────────────┤  Properties panel    │
│          │  Main content (flex-1)       │  (w-80, optional)    │
└──────────┴──────────────────────────────┴──────────────────────┘

• Sidebar: w-60, collapsible, contains CompanySwitcher + SidebarSections
• Properties panel: w-80, shown on detail views, hidden on lists
• Main content: scrollable, flex-1

10. The /design-guide Page

Location: ui/src/pages/DesignGuide.tsx Route: /design-guide

This is the living showcase of every component and pattern in the app. It is the source of truth for how things look.

Rules

1. When you add a new reusable component, you MUST add it to the design guide page. Show all variants, sizes, and states.
2. When you modify an existing component's API, update its design guide section.
3. When you add a new composition pattern, add a section demonstrating it.
4. Follow the existing structure: <Section title="..."> wrapper with <SubSection> for grouping.
5. Keep sections ordered logically: foundational (colors, typography) first, then primitives, then composites, then patterns.

Adding a New Section

<Section title="My New Component">
  <SubSection title="Variants">
    {/* Show all variants */}
  </SubSection>
  <SubSection title="Sizes">
    {/* Show all sizes */}
  </SubSection>
  <SubSection title="States">
    {/* Show interactive/disabled states */}
  </SubSection>
</Section>

11. Component Index

See references/component-index.md for the full component inventory.

When you create a new reusable component:

1. Add it to the component index reference file
2. Add it to the /design-guide page
3. Follow existing naming and file conventions

12. File Conventions

• shadcn primitives: ui/src/components/ui/{component}.tsx — lowercase, kebab-case
• Custom components: ui/src/components/{ComponentName}.tsx — PascalCase
• Pages: ui/src/pages/{PageName}.tsx — PascalCase
• Utilities: ui/src/lib/{name}.ts
• Hooks: ui/src/hooks/{useName}.ts
• API modules: ui/src/api/{entity}.ts
• Context providers: ui/src/context/{Name}Context.tsx

All components use cn() from @/lib/utils for className merging. All components use CVA for variant definitions when they have multiple visual variants.

13. Common Mistakes to Avoid

• Using raw hex/rgb colors instead of CSS variable tokens
• Creating ad-hoc typography styles instead of using the established scale
• Hardcoding status colors instead of using StatusBadge/StatusIcon
• Building one-off styled elements when a reusable component exists
• Adding components without updating the design guide page
• Using shadow-md or heavier — keep shadows minimal (xs, sm only)
• Using rounded-2xl or larger — max is rounded-xl (except rounded-full for pills)
• Forgetting dark mode — always use semantic tokens, never hardcode light/dark values
