Overview

The LLM::Schema class represents a JSON schema, and provides methods that let you describe and produce a schema that can be used in various contexts that include the validation and generation of JSON data.

Examples:

JavaScript-style

schema = LLM::Schema.new
schema.object({
  name: schema.string.enum("John", "Jane").required,
  age: schema.integer.required,
  hobbies: schema.array(schema.string).required,
  address: schema.object({street: schema.string}).required,
})

Ruby-style

class Address < LLM::Schema
  property :street, String, "Street address", required: true
end

class Person < LLM::Schema
  property :name, String, "Person's name", required: true
  property :age, Integer, "Person's age", required: true
  property :hobbies, Array[String], "Person's hobbies", required: true
  property :address, Address, "Person's address", required: true
end
