You must also make sure: - all fields in an object are set as required - I REPEAT, ALL FIELDS MUST BE MARKED AS REQUIRED - all objects must have additionalProperties set to false - because of this, some cases like "attributes" or "metadata" properties that would normally allow additional properties should instead have a fixed set of properties - all objects must have properties defined - field order matters. any form of "thinking" or "explanation" should come before the conclusion - $defs must be defined under the schema param Notable keywords NOT supported include: - For strings: minLength, maxLength, pattern, format - For numbers: minimum, maximum, multipleOf - For objects: patternProperties, unevaluatedProperties, propertyNames, minProperties, maxProperties - For arrays: unevaluatedItems, contains, minContains, maxContains, minItems, maxItems, uniqueItems Other notes: - definitions and recursion are supported - only if necessary to include references e.g. "$defs", it must be inside the "schema" object # Examples Input: Generate a math reasoning schema with steps and a final answer.
