What problem does it solve? Wiring a new syncable entity into Twenty's workspace migration system requires registering services across multiple NestJS modules and correctly layering services and resolvers, which is error-prone without a clear guide. ## Core Features & Use Cases - Module Registration: Register migration builders, validators, and action handlers in the correct NestJS modules with proper providers and exports. - Service Layer Creation: Build services that transform input to universal flat entities, run validate-build-and-run migrations, and return flat entities. - Resolver Layer with DTO Conversion: Expose entities via GraphQL mutations using an exception interceptor and flat-to-DTO conversion utilities. - Use Case: After defining a new metadata entity's types and migration logic, use this Skill to wire it into the builder module, validators module, and action handlers module, then expose create/update/delete mutations through the GraphQL API. ## Quick Start Wire my new entity into the Twenty workspace migration modules and create its service and GraphQL resolver following the syncable entity integration pattern.
