## 3. COMPOSABLE FUNCTIONS - DETAILED BREAKDOWN

### useCart.ts (109 lines)

**Purpose:** Cart/stack builder with persistent localStorage.

**State:**

```typescript
const items = ref<CartItem[]>([]);
const STORAGE_KEY = "vibery-cart";
let initialized = false;
let watcherSetup = false;
```

**Key Features:**

- **Auto-persistence:** Watches cart changes → saves to localStorage
- **Hydration safety:** Defers load to `onMounted()` to avoid SSR mismatches
- **Debounced save:** Single watcher handles all mutations

**Exports:**

| Function            | Returns  | Purpose                              |
| ------------------- | -------- | ------------------------------------ |
| `addItem(item)`     | boolean  | Add if not exists, return success    |
| `removeItem(name)`  | void     | Remove by name                       |
| `clearCart()`       | void     | Empty cart                           |
| `hasItem(name)`     | boolean  | Check if item exists                 |
| `toggleItem(item)`  | boolean  | Add/remove, return new state         |
| `generateCommand()` | string   | Build `vibery install x y z` command |
| `getIcon(type)`     | string   | Map TemplateType → Phosphor icon     |
| `count`             | computed | Reactive item count                  |
| `items`             | computed | Reactive item array                  |

**Storage Format:** JSON stringified CartItem[]

### useModal.ts (34 lines)

**Purpose:** Global modal state for template details.

**State:**

```typescript
const isOpen = ref(false);
const currentTemplate = ref<Template | null>(null);
```

**Exports:**

| Function              | Purpose                                    |
| --------------------- | ------------------------------------------ |
| `openModal(template)` | Set template, open modal, lock body scroll |
| `closeModal()`        | Clear template, close modal, unlock scroll |
| `isOpen`              | Reactive open/closed state                 |
| `currentTemplate`     | Reactive current template data             |

**Side Effects:** Manages `document.body.overflow` to prevent scroll while modal open

### useNotifications.ts (47 lines)

**Purpose:** Toast notification system with auto-dismiss.

**State:**

```typescript
const notifications = ref<Notification[]>([]);
let notificationId = 0;

interface Notification {
  id: number;
  message: string;
  type: "success" | "error" | "info" | "warning";
  duration: number;
}
```

**Exports:**

| Function                                | Purpose                                       |
| --------------------------------------- | --------------------------------------------- |
| `showNotification(msg, type, duration)` | Add notification, auto-dismiss after duration |
| `removeNotification(id)`                | Manually remove by ID                         |
| `notifications`                         | Reactive notification array                   |

**Auto-Dismiss:** setTimeout fires after duration (default 2500ms)

**State:**

```typescript
const query = ref("");
```

**Exports:**

| Function             | Parameters    | Returns | Purpose                          |
| -------------------- | ------------- | ------- | -------------------------------- |
| `filteredItems<T>()` | items: T[]    | T[]     | Filter by query (name/type/desc) |
| `setQuery(value)`    | value: string | void    | Update search query              |
| `clearQuery()`       | —             | void    | Clear query                      |
| `query`              | —             | Ref     | Reactive search term             |

**Matching:** Case-insensitive substring match on name, type, description

### useUsageStats.ts (75 lines)

**Purpose:** Track template interactions (copy-to-clipboard, downloads).

**State:**

```typescript
const stats = ref<UsageStats>({});
const STORAGE_KEY = "vibery-usage-stats";

interface UsageStats {
  [templateName: string]: {
    copies: number;
    downloads: number;
    lastUsed: number;
  };
}
```

**Exports:**

| Function              | Purpose                                                |
| --------------------- | ------------------------------------------------------ |
| `trackCopy(name)`     | Increment copies, update lastUsed                      |
| `trackDownload(name)` | Increment downloads, update lastUsed                   |
| `getScore(name)`      | Compute: `copies * 2 + downloads` (copies weighted 2x) |
| `getStats(name)`      | Return stat object or zeros                            |
| `stats`               | Reactive stats object                                  |

**Scoring:** Copies count more than downloads (2x weight)

export interface CartItem {
  name: string;
  type: TemplateType;
  description?: string;

## 5. DATA RELATIONSHIPS & DATA FLOW

### Relationship Graph

```
templates.json (600+ templates)
    ↓
    ├─→ stacks.json (references by name)
    │   └─→ 12 Smart Stacks
    │       └─→ bundles 4-6 templates each
    │
    ├─→ outcomes.json (references by name)
    │   └─→ 8 outcome flows
    │       ├─→ 4 branches each
    │       └─→ resultStack points to stacks.json
    │
    └─→ claudekit.json (separate, non-template registry)
        ├─→ 14 Claude Code agents
        ├─→ 35+ commands
        └─→ metadata for website navigation
```

### Component Data Flow

```
Vue Component (e.g., StackCard)
    ↓
    ├─→ useCart() ← localStorage persistence
    │   ├─→ addItem() → CartItem[]
    │   └─→ generateCommand() → "vibery install x y z"
    │
    ├─→ useNotifications() ← auto-dismiss toasts
    │   └─→ showNotification() → "Copied to cart"
    │
    ├─→ useModal() ← template details drawer
    │   └─→ openModal(template) → show full content
    │
    ├─→ useSearch() ← live filtering
    │   └─→ filteredItems(templates) → filtered array
    │
    └─→ useUsageStats() ← analytics
        ├─→ trackCopy() → increment copies
        └─→ getScore() → popularity ranking
```

### Template Reference Resolution

```
Stack Reference:
stacks.json → nextjs-production
  ├─→ templates[0]: { type: 'agent', name: 'nextjs-architecture-expert' }
  ├─→ templates[1]: { type: 'agent', name: 'react-performance-optimizer' }
  └─→ ...

Resolution:
  name → look up in templates.json[agents]
  → get full Agent object with content
  → pass to useCart → CartItem
  → generateCommand() → "vibery install nextjs-architecture-expert ..."
```

### Outcome Branch Flow

```
outcomes.json → secure-codebase
  └─→ branches[0]: find-vulnerabilities
      ├─→ templates (array of refs)
      │   └─→ { type: 'agent', name: 'security-auditor' }
      └─→ resultStack: "security-hardening"
          ↓ (references stacks.json)
          └─→ Load full stack bundle
```

## 6. STORAGE & PERSISTENCE STRATEGY

### localStorage Keys

| Key                  | Composable    | Structure        | Persistence           |
| -------------------- | ------------- | ---------------- | --------------------- |
| `vibery-cart`        | useCart       | JSON(CartItem[]) | Manual save on change |
| `vibery-usage-stats` | useUsageStats | JSON(UsageStats) | Manual save on track  |

### Initialization Pattern

1. **SSR Safety:** Both check `typeof window !== 'undefined'`
2. **Hydration:** useCart defers load to `onMounted()`
3. **Startup:** useUsageStats loads immediately if browser
4. **Watch:** useCart auto-saves with deep watcher

### Icon Mapping (useCart.getIcon)

```typescript
{
  agent: 'ph-robot',
  command: 'ph-terminal',
  mcp: 'ph-plug',
  setting: 'ph-gear',
  hook: 'ph-webhooks-logo',
  skill: 'ph-magic-wand',
  default: 'ph-package'
}
```

## 7. KEY INSIGHTS

### Data Consistency

- **One source:** templates.json is authoritative
- **No duplication:** stacks/outcomes reference by name only
- **Type safety:** CartItem matches Template structure
- **Icon coverage:** All TemplateTypes have mappings

### Composable Architecture

- **Loose coupling:** Composables don't import each other
- **Shared types:** All use Template/TemplateType from types/
- **Independent lifecycle:** Each manages own state
- **Optional analytics:** useUsageStats purely optional

### Performance Notes

- **Cart watch:** Deep watcher + localStorage = 1-2ms saves
- **Search:** O(n) linear filter (acceptable for 600 templates)
- **Notifications:** Auto-cleanup prevents memory leaks
- **Usage stats:** Lightweight, localStorage-backed

## 8. UNRESOLVED QUESTIONS

1. **templates.json bloat:** 1,413 lines for 600+ templates. Should split by type?
2. **claudekit.json usage:** Is this for website sidebar or CLI tool navigation?
3. **Null resultStack:** When outcomes branch has `resultStack: null`, what should UI display?
4. **Search debounce:** Does useSearch.setQuery() get debounced or hammer filters?
5. **Stats migration:** If templates.json updates, how do usage stats evolve?
