Schema-driven test data factory generator. Reads your database schema or model definitions — Prisma schema, SQLAlchemy models, Django models, TypeORM entities, Zod schemas, Pydantic models, or raw SQL DDL — and generates ready-to-use factory functions with realistic fake data. Outputs TypeScript factory files using Faker.js, Python conftest.py using factory_boy + Faker, or raw SQL INSERT seed scripts. Respects foreign key relationships (seeds parents before children), handles enums, nullable fields, unique constraints, and generates edge-case variants (empty strings, max-length values, boundary dates). Zero external API — pure local file analysis + code generation. Triggers on "generate test data", "seed database", "test fixtures", "factory functions", "fake data from schema", "/test-data-factory".

From the source SKILL.md

Writing test setup is slower than writing the test itself. You have a User model with 12 fields, a Post model that requires a User, and an Order model that requires both. Every test file re-invents the same createTestUser() boilerplate — with slightly different hardcoded values that don't cover edge cases.

What this skill does
