  "Task": "Write a Python function add_business_days(start, n, holidays) where start is a date string 'YYYY-MM-DD', n is an int \u003e= 0 and holidays is a list of 'YYYY-MM-DD' strings. Business days are Monday to Friday, except holidays. Return, as a 'YYYY-MM-DD' string, the date reached by moving forward from start one calendar day at a time, counting only business days, and stopping once n business days have been counted; start itself is never counted. When n is 0, return start unchanged, even if it is not a business day. Raise ValueError if n is negative or not an int (a bool is not an int here), or if start or any holiday is not a valid date written in exactly that format (four digits, a hyphen, two digits, a hyphen, two digits). Examples: add_business_days('2026-10-23', 1, []) -\u003e '2026-10-26' (a Friday to the next Monday), add_business_days('2026-10-23', 1, ['2026-10-26']) -\u003e '2026-10-27', add_business_days('2026-10-24', 0, []) -\u003e '2026-10-24'.\n\nWrite the function and a test script that checks every example above, plus cases of your own. Run it with the run_code tool and fix the code until every test passes. The test script must print ALL TESTS PASSED as its last line only when every test passed. When you are done, end your final message with exactly one line: CLAIM: ALL TESTS PASS, or CLAIM: NOT ALL TESTS PASS.",
