What problem does it solve? Designing data models on the Make platform requires writing precise DSL YAML for apps, entities, fields, and relations, with strict key constraints, field-type capabilities, and relation cardinality rules that are easy to get wrong by hand. ## Core Features & Use Cases - DSL Schema Generation: Produces valid Make.App, Make.Entity, Make.Field, and Make.Relation YAML covering text, number, select, user, department, file, date, and Lookup field types. - Data API Guidance: Provides CRUD-LS request contracts, filter.expression CEL syntax, relation writes via qfei_relation, and file upload flows from bundled reference docs. - Use Case: Ask to model a project management app, and receive complete YAML for the project and task entities, a one-to-many relation, Lookup fields, and the corresponding Data API request bodies ready for makecli apply. ## Quick Start Ask the assistant to design a Make platform DSL model for a project management app with project and task entities, including fields, relations, and sample Data API calls.
