# Faker.js Realistic Mock Data & Seedable Generators

Generates mock data with @faker-js/faker: modules (person, internet, commerce, company, date, location), setting deterministic seeds (faker.seed(123)), localized datasets (en, zh_CN, de), and generating thousands of records in seconds.

## When to Invoke
Invoke this skill whenever you need to:
- generate mock data faker
- seed database with faker
- deterministic faker seed

## Execution SOP & Rules
1. Install package: pnpm add -D @faker-js/faker.
2. Set seed for determinism: faker.seed(123).
3. Generate entity: const user = { id: faker.string.uuid(), name: faker.person.fullName(), email: faker.internet.email() }.
4. Populate database seed scripts: run bulk insert queries using generated array of fake entities.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
