Agent structured output

For the initial version there will not be a YAML converter - the issue with this is if you are streaming the output, how are we supposed to react on that. So, this is pushed until later.

I have tested this with the math reasoning example given here.

Created a Math tutor agent with instruction 'You are a helpful math tutor. Guide the user through the solution step by step'
Enabled structured output option and gave the following schema

{
  "name": "math_reasoning",
  "schema": {
    "type": "object",
    "properties": {
      "steps": {
        "type": "array",
        "items": {
          "type": "object",
          "properties": {
            "explanation": { "type": "string" },
            "output": { "type": "string" }
          },
          "required": ["explanation", "output"],
          "additionalProperties": false
        }
      },
      "final_answer": { "type": "string" }
    },
    "required": ["steps", "final_answer"],
    "additionalProperties": false
  },
  "strict": true
}

Then using Agents explorer, asked the agent to solve 'what is x and y, if 3x + 2y = 36 and 2x - y = 17'. It gave the output in the proper json format.

{
  "steps": [
    {
      "explanation": "First, let's write down the system of equations: 3x + 2y = 36 (1), and 2x - y = 17 (2). Let's solve equation (2) for y.",
      "output": "2x - y = 17 => y = 2x - 17"
    },
    {
      "explanation": "Now substitute y = 2x - 17 into equation (1): 3x + 2y = 36 becomes 3x + 2(2x - 17) = 36.",
      "output": "3x + 4x - 34 = 36"
    },
    {
      "explanation": "Combine like terms: 3x + 4x = 7x, and move -34 to the other side: 7x = 36 + 34 = 70.",
      "output": "7x = 70"
    },
    {
      "explanation": "Solve for x by dividing both sides by 7.",
      "output": "x = 10"
    },
    {
      "explanation": "Now we substitute x = 10 into y = 2x - 17 to find y.",
      "output": "y = 2*10 - 17 = 20 - 17 = 3"
    }
  ],
  "final_answer": "x = 10, y = 3"
}
