Fix Type Cast

The model receives the prompt (and optional system message). The run uses scorer contains_any with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Fix the bug and return corrected Python code only.

def add_one(x):
    return x + "1"

{
  "expected_contains": [
    "int(x) + 1",
    "x + 1"
  ]
}
