def self.fix_ar_code(failed_code, error_message)

  prompt = <<~PROMPT
    The following Ruby/ActiveRecord expression failed to execute:
    ```ruby
    #{failed_code}
    ```

    The error returned was:
    "#{error_message}"

    Your task is to correct the Ruby expression so it becomes valid and read-only.
    - Return ONLY the corrected Ruby expression (optionally in a ```ruby block).
    - Do not provide explanations or comments.
    - Ensure it uses only read methods (where, joins, select, count, sum, pluck, etc.).
    - NEVER use .destroy, .delete, .update, .save, .create, or any write method.
