JSON Mode | Provide Schema? Accurate?

I’m concerned on the accuracy of the keys in response as the nested and long structure could potentially lead to issues

Here’s the JSON structure for reference:

{
  "categories": [
    {
      "Category": "string",
      "Rating": "number",
      "Strengths": "string",
      "Weaknesses": "string",
      "Recommendations": "string"
    },
    {
      ...
    }
  ]
}

It contains around 6 similar categories, and I’ll be providing descriptions on each value.
