Functions: Support for minItems and maxItems for json schema array

[tjhiggins]

Describe the feature or improvement you're requesting

First off - let me just say how great functions are! Game changer!

It would be really cool if the functions would respect validation like minItems and maxItems for an array. If I explicitly put the number of questions I want in the function description it works, but I half expected it to work when setting minItems. Unfortunately, if I specify minItems: 10 it only returns 5 questions.

I'd imagine other json schema validation options are ignored, and this could be a more generic ticket.

const func = {
  name: "generateQuiz",
  description: "Generate a questions about a given topic",
  parameters: {
    type: "object",
    properties: {
      topics: {
        type: "array",
        items: {
          type: "string",
          description: "Topic of the lesson, e.g. Planes",
        },
      },
      questions: {
        type: "array",
        minItems: 10,
        maxItems: 20,
        description:
          "Questions, e.g. What is the primary function of an airplane?",
        items: {
          type: "object",
          properties: {
            question: {
              type: "string",
              description:
                "Question, e.g. What is the primary function of an airplane?",
            },
            answer: {
              type: "string",
              description: "Answer for the question",
            },
          },
          required: ["question", "answer"],
        },
      },
    },
    required: ["topic", "questions"],
  },
};
