Use this skill to create typed test data builders with mimicry-js and Faker for any TypeScript interface or type. Invoke whenever the user asks to generate mock data, create test fixtures, build factory functions, produce seed data, or construct fake objects for unit tests, Storybook stories, or E2E scenarios. Also use when migrating from test-data-bot or Fishery to mimicry-js, or when the user mentions builders, factories, or typed mock/fake/test/seed data generation — even if they describe the task indirectly (e.g. "I need realistic invoices for testing" or "generate sample users for my stories").
