+name: theme-system
+description: Use when creating or modifying UI components, styling, or visual elements in OpenChamber. All UI colors must use theme tokens - never hardcoded values or Tailwind color classes.
+license: MIT
+compatibility: opencode
+---
+
+## Overview
+
+OpenChamber uses a JSON-based theme system. Themes are defined in `packages/ui/src/lib/theme/themes/`. Users can also add custom themes via `~/.config/openchamber/themes/`.
+
+**Core principle:** UI colors must use theme tokens - never hardcoded hex colors or Tailwind color classes.
+
+## When to Use
+
+- Creating or modifying UI components
+- Working with colors, backgrounds, borders, or text
+
+## Quick Decision Tree
+
+1. **Code display?** → `syntax.*`
+2. **Feedback/status?** → `status.*`
+3. **Primary CTA?** → `primary.*`
+4. **Interactive/clickable?** → `interactive.*`
+5. **Background layer?** → `surface.*`
+6. **Text?** → `surface.foreground` or `surface.mutedForeground`
+
+## Critical Rules
+
+- `surface.elevated` = inputs, cards, panels
+- `interactive.hover` = **ONLY on clickable elements**
+- `interactive.selection` = active/selected states (not primary!)
+- Status colors = **ONLY for actual feedback** (errors, warnings, success)
+- Input footers = `bg-transparent` on elevated background
+
+### Never Use
+
+- Hardcoded hex colors (`#FF0000`)
+- Tailwind colors (`bg-white`, `text-blue-500`, `bg-gray-*`)
+- Deprecated: `bg-secondary`, `bg-muted`
+
+## Usage
+
+### Via Hook
+```tsx
+import { useThemeSystem } from '@/contexts/useThemeSystem';
+const { currentTheme } = useThemeSystem();
+
+<div style={{ backgroundColor: currentTheme.colors.surface.elevated }}>
+```
+
+### Via CSS Variables
+```tsx
+<div className="bg-[var(--surface-elevated)] hover:bg-[var(--interactive-hover)]">
+```
+
+## Color Tokens
+
+### Surface Colors
+
+| Token | Usage |
+|-------|-------|
+| `surface.background` | Main app background |
+| `surface.elevated` | Inputs, cards, panels, popovers |
+| `surface.muted` | Secondary backgrounds, sidebars |
+| `surface.foreground` | Primary text |
+| `surface.mutedForeground` | Secondary text, hints |
+| `surface.subtle` | Subtle dividers |
+
+### Interactive Colors
+
+| Token | Usage |
+|-------|-------|
+| `interactive.border` | Default borders |
+| `interactive.hover` | Hover on **clickable elements only** |
+| `interactive.selection` | Active/selected items |
+| `interactive.selectionForeground` | Text on selection |
+| `interactive.focusRing` | Focus indicators |
+
+### Status Colors
+
+| Token | Usage |
+|-------|-------|
+| `status.error` | Errors, validation failures |
+| `status.warning` | Warnings, cautions |
+| `status.success` | Success messages |
+| `status.info` | Informational messages |
+
+Each has variants: `*`, `*Foreground`, `*Background`, `*Border`.
+
+### Primary Colors
+
+| Token | Usage |
+|-------|-------|
+| `primary.base` | Primary CTA buttons |
+| `primary.hover` | Hover on primary elements |
+| `primary.foreground` | Text on primary background |
+
+**Primary vs Selection:** Primary = "click me" (CTA), Selection = "currently active" (state).
+
+### Syntax Colors
+
+For code display only. Never use for UI elements.
+
+| Token | Usage |
+|-------|-------|
+| `syntax.base.background` | Code block background |
+| `syntax.base.foreground` | Default code text |
+| `syntax.base.keyword` | Keywords |
+| `syntax.base.string` | Strings |
+| `syntax.highlights.diffAdded` | Added lines |
+| `syntax.highlights.diffRemoved` | Removed lines |
+
+## Examples
+
+### Input Area
+
+```tsx
+const { currentTheme } = useThemeSystem();
+
+<div style={{ backgroundColor: currentTheme.colors.surface.elevated }}>
+  <textarea className="bg-transparent" />
+  <div className="bg-transparent">{/* Footer - transparent! */}</div>
+</div>
+```
+
+### Active Tab
+
+```tsx
+<button className={isActive 
+  ? 'bg-interactive-selection text-interactive-selection-foreground'
+  : 'hover:bg-interactive-hover/50'
+}>
+```
+
+### Error Message
+
+```tsx
+<div style={{ 
+  color: currentTheme.colors.status.error,
+  backgroundColor: currentTheme.colors.status.errorBackground 
+}}>
+```
+
+### Card
+
+```tsx
+<div style={{ backgroundColor: currentTheme.colors.surface.elevated }}>
+  <h3 style={{ color: currentTheme.colors.surface.foreground }}>Title</h3>
+  <p style={{ color: currentTheme.colors.surface.mutedForeground }}>Description</p>
+</div>
+```
+
+## Wrong vs Right
+
+### Wrong
+
+```tsx
+// Hardcoded colors
+<div style={{ backgroundColor: '#F2F0E5' }}>
+<button className="bg-blue-500">
+
+// Primary for active tab
+<Tab className="bg-primary">Active</Tab>
+
+// Hover on static element
+<div className="hover:bg-interactive-hover">Static card</div>
+
+// Colored footer on input
+<div style={{ backgroundColor: currentTheme.colors.surface.elevated }}>
+  <textarea />
+  <div style={{ backgroundColor: currentTheme.colors.surface.muted }}>Footer</div>
+</div>
+```
+
+### Right
+
+```tsx
+// Theme tokens
+<div style={{ backgroundColor: currentTheme.colors.surface.elevated }}>
+<button style={{ backgroundColor: currentTheme.colors.primary.base }}>
+
+// Selection for active tab
+<Tab style={{ backgroundColor: currentTheme.colors.interactive.selection }}>Active</Tab>
+
+// Hover only on clickable
+<button className="hover:bg-[var(--interactive-hover)]">Click</button>
+
+// Transparent footer
+<div style={{ backgroundColor: currentTheme.colors.surface.elevated }}>
+  <textarea className="bg-transparent" />
+  <div className="bg-transparent">Footer</div>
+</div>
+```

+# Adding Themes
+
+## Custom Themes (User)
+
+Drop a JSON file into `~/.config/openchamber/themes/`. No rebuild needed.
+
+1. Create theme file (e.g., `my-theme.json`)
+2. In app: **Settings → Theme → Reload themes**
+3. Select from dropdown
+
+See `docs/CUSTOM_THEMES.md` for full format reference.
+
+## Built-in Themes (Development)
+
+### 1. Create JSON Files
+
+Add to `packages/ui/src/lib/theme/themes/`:
+- `<id>-light.json`
+- `<id>-dark.json`
+
+Use existing themes (e.g., `flexoki-dark.json`) as reference for the full structure.
+
+### 2. Register in presets.ts
+
+```typescript
+import mytheme_light_Raw from './mytheme-light.json';
+import mytheme_dark_Raw from './mytheme-dark.json';
+
+export const presetThemes: Theme[] = [
+  // ... existing themes
+  mytheme_light_Raw as Theme,
+  mytheme_dark_Raw as Theme,
+];
+```
+
+### 3. Validate
+
+```bash
+bun run type-check && bun run lint && bun run build
+```

+## Theme System (MANDATORY for UI work)
+
+When working on any UI components, styling, or visual changes, agents **MUST** study the theme system skill first.
+
+**Before starting any UI work:**
+```
+skill({ name: "theme-system" })

+   ```bash
+   mkdir -p ~/.config/openchamber/themes
+   ```
+
+2. Create a theme JSON file (e.g., `my-theme.json`) with the format below.
+
+3. In OpenChamber: **Settings → Theme → Reload themes**.
+
+4. Select your theme from the dropdown.
+
+## Theme Location

+## Validation
+
+Themes are validated on load. Invalid themes are skipped with a console warning.
+
+Common issues:
+- Missing required fields
+- Invalid `variant` (must be `"light"` or `"dark"`)
+- File size > 512KB
+
+## Tips
+
+- Use hex with alpha for transparency (e.g., `#FFFFFF20`)
+- Reference built-in themes in `packages/ui/src/lib/theme/themes/` for more examples
+- Theme `id` must be unique; duplicates are skipped

+/**
+ * VS Code Theme to OpenChamber Theme Converter
+ * 
+ * USAGE:
+ *   node scripts/convert-vscode-theme.cjs <path-to-vscode-theme.json>
+ * 
+ * EXAMPLE:
+ *   node scripts/convert-vscode-theme.cjs \
+ *     /path/to/dune-kaitain-color-theme.json
+ * 
+ * WHAT IT DOES:
+ *   1. Reads a VS Code theme JSON file (with comments support)
+ *   2. Converts it to OpenChamber theme format:
+ *      - Extracts color palette (primary, surface, interactive, status, syntax)
+ *      - Generates derived sections (markdown, chat, tools)
+ *      - Adds default config (fonts, radius, transitions)
+ *   3. Saves the converted theme to:
+ *      packages/ui/src/lib/theme/themes/<theme-id>.json
+ *   4. Auto-registers the theme in presets.ts:
+ *      - Adds import statement
+ *      - Adds to presetThemes array
+ *      - Skips if already registered (no duplicates)
+ * 
+ * OUTPUT:
+ *   - Theme file: packages/ui/src/lib/theme/themes/<theme-name>-<variant>.json
+ *   - Updated: packages/ui/src/lib/theme/themes/presets.ts
+ * 
+ * COMPATIBILITY:
+ *   Works with standard VS Code themes that have:
+ *   - colors (UI colors)
+ *   - tokenColors (TextMate scopes)
+ *   - semanticTokenColors (optional, LSP tokens)
