 "prompt": "Net pay for 40 employees changed more than 10% from the last run. Here is the data. Explain each change.",
 "system": "You are a payroll assistant at a US company. Answer the request.",

 "response": "The data didn't come through. I only see your message, with no file, table, or pasted rows. Could you re-send it? Pasting the rows directly works best, or you can attach a CSV or Excel export.\n\n## What to include\n\nFor each of the 40 employees, current run vs. prior run:\n\n- **Identifiers:** employee ID or name, pay frequency, pay type (hourly or salaried)\n- **Earnings:** regular hours and pay, overtime, PTO/sick/holiday, bonus, commission, retro pay, other earnings codes\n- **Pre-tax deductions:** 401(k)/403(b), health/dental/vision, HSA/FSA\n- **Taxes:** federal withholding, Social Security, Medicare, state and local\n- **Post-tax deductions:** garnishments, Roth 401(k), loans, union dues, etc.\n- **Gross pay and net pay**\n- **Helpful if available:** recent W-4 or state form changes, benefit enrollment changes, hire/term/leave dates, rate changes, address changes\n\nIf you'd rather not share names or SSNs, employee IDs are fine.\n\n## What I'll do with it\n\nFor each employee, I'll identify the specific line items driving the change. Typical causes I'll check for:\n\n| Category | Common causes |\n|---|---|\n| **Earnings** | Overtime spikes, bonus/commission, unpaid leave, partial period (new hire, termination, rate change mid-period), retro pay, PTO payout, a 3rd paycheck month for biweekly benefits |\n| **Taxes** | Supplemental wage withholding on bonuses (22% federal flat rate), W-4 changes, hitting the Social Security wage base ($176,100 for 2025) so OASDI stops, Additional Medicare Tax kicking in above $200K, state/local jurisdiction changes |\n| **Deductions** | Open enrollment or benefit elections, 401(k) % changes or hitting the annual limit, new or ended garnishments, deduction catch-ups or skipped deductions, loan payoffs |\n| **Errors to flag** | Duplicate earnings, missing hours, wrong rate, deductions taken twice or not at all, incorrect tax setup |\n\n## What you'll get back\n\nA per-employee explanation, for example:\n\n> **EMP 1042:** Net pay +18% ($2,140 \u2192 $2,525). Driven by 6.5 OT hours ($312) and Social Security max reached on 11/15 ($96 less withheld). No issues.\n\nI'll also give you a summary of patterns (e.g., \"22 of 40 changes are due to open enrollment taking effect\") and a list of any changes that look like possible errors to review before you finalize the run.\n\nSend the data whenever you're ready.",
