Is it impossible to construct this simple JSON schema for a function definition?

[SwiftedMind]

Hey,

so, I might just be stupid but I struggle with building a very simple JSON object schema as a tool.

What I want is this:

{
  "name": "Name",
  "parameters": {
    "type": "object",
    "properties": {
      "key": {
        "type": "object",
        "properties": {
          "anotherKey": "value"
        }
      }
    }
  }
}

But this seems impossible to build with ChatQuery.ChatCompletionToolParam.FunctionDefinition:

let tool = ChatQuery.ChatCompletionToolParam.FunctionDefinition(
  name: "name",
  parameters: .init(
    type: .object,
    properties: [
      "key": .init(
        type: .object,
        // cant' use "properties" here, there's just "items", which is technically not allowed
      )
    ]
  )
)

Is there a trick to this? Or am I doing something wrong?

Thanks!

Hy @SwiftedMind , thanks for the question! I am not familiar that much with this part of code, so can't tell you right away, but it seems like pretty... rigid, and there is a chance it might not allow you to do what you need.

But, I remember that sometime ago a user asked for a dynamic way to define json schema, let me find the PR and see if we can use that

Hey, thanks for the fast answer! 🙂 It's not urgent or anything, I can easily work around this at the moment, I was just wondering if I misunderstood something with the way these function definitions work (I usually do 😅).

No, I don't think you miss anything. FunctionDefinition.FunctionParameters is currently hardcoded to predefined fields names, whereas it seems that it should be... any JSONSchema you'd want to define. Like, it should probably just be [String: Any] or something like that, where you could define any key/value pair

[nezhyborets]

I will have to fix that, but I'm not sure yet when I'll be able to do that

[SwiftedMind]

Okay, thanks :) No rush
