HaimKortovich a2eb1f3789 Add nuxt-skills and update auto quotes to use new policy API structure

- Add nuxt-skills (vue, nuxt, nuxt-ui) to .claude/skills/
- Create useCustomerSelection() composable for managing insured/buyer selection
- Create usePolicyApi() composable for policy API operations
- Update auto quote components to use insured/buyer instead of client
- Update vehicle fields: remove valorVehiculo, add market_value, requested_value, rc_limits
- Make chassis_number and engine_number optional
- Update auto quote types and composables to match new API structure
- Update auto quote page to submit to policy API with new structure

Client Utilities

Pure functions for formatting, validation, transformation, and parsing.

Quick Reference

Category	Examples
Formatters	`formatCurrency`, `formatDate`, `formatBytes`
Validators	`isValidEmail`, `isValidUrl`, `isValidPhone`
Transformers	`slugify`, `truncate`, `capitalize`
Parsers	`parseQuery`, `parseJSON`, `parseDate`

Rules

Pure functions:

Same input → same output
No side effects
No external state mutation
No API calls, no refs, no reactive

When NOT to use utils:

Stateful logic → use composables
Vue-specific → use composables
Component logic → keep in component
API calls → use queries

Structure

// utils/formatters.ts
export function formatCurrency(amount: number, currency = 'USD'): string {
  return new Intl.NumberFormat('en-US', {
    style: 'currency',
    currency,
  }).format(amount)
}

export function formatRelativeTime(date: Date): string {
  const rtf = new Intl.RelativeTimeFormat('en', { numeric: 'auto' })
  const diff = date.getTime() - Date.now()
  const days = Math.floor(diff / (1000 * 60 * 60 * 24))
  return rtf.format(days, 'day')
}

Naming: Descriptive verbs (formatCurrency, validateEmail, parseQuery) Organization: Group by category (formatters.ts, validators.ts) Exports: Named exports only

Examples by Category

Formatters:

// utils/formatters.ts
export function formatBytes(bytes: number): string { ... }
export function formatPhone(phone: string): string { ... }

Validators:

// utils/validators.ts
export function isValidEmail(email: string): boolean {
  return /^[^\s@]+@[^\s@][^\s.@]*\.[^\s@]+$/.test(email)
}

export function isValidUrl(url: string): boolean {
  try { new URL(url); return true }
  catch { return false }
}

Transformers:

// utils/transformers.ts
export function slugify(text: string): string {
  return text.toLowerCase()
    .replace(/[^\w\s-]/g, '')
    .replace(/\s+/g, '-')
}

export function truncate(text: string, length: number): string {
  return text.length > length ? `${text.slice(0, length)}...` : text
}

Parsers:

// utils/parsers.ts
export function parseQuery(search: string): Record<string, string> {
  return Object.fromEntries(new URLSearchParams(search))
}

export function parseJSON<T>(json: string, fallback: T): T {
  try { return JSON.parse(json) }
  catch { return fallback }
}

Common Mistakes

Side effects (not pure):

// ❌ Wrong - mutates external state
let count = 0
export function increment() {
  count++
  return count
}

// ✅ Correct - pure
export function add(a: number, b: number): number {
  return a + b
}

Using utils for stateful logic:

// ❌ Wrong - should be composable
export function useCounter() { ... }

// ✅ Correct - pure transformation
export function formatCount(count: number): string { ... }

Organization

Flat for small projects:

utils/
├── formatters.ts
├── validators.ts
└── transformers.ts

Nested for large projects:

utils/
├── formatters/
│   ├── date.ts
│   ├── currency.ts
│   └── index.ts
└── validators/
    ├── email.ts
    └── index.ts
