Summary

Exact prompt

# Run hourly payroll for a two-week period Inputs: `employees.csv` (pay type and hourly rate), `punches.csv` (clock-in and clock-out times, local time) and `pay-period.json` (period, week starts, holidays). Report gross pay for every hourly employee for the two-week period. Salaried employees are paid elsewhere; leave them out. - Shift length = clock_out minus clock_in. A shift longer than 6 hours has a 30-minute unpaid break deducted. A shift of exactly 6 hours or less has none. - A shift belongs to the day and the week in which it starts, even if it ends after midnight. - The punch clock sometimes re-sends a punch: rows with the same employee and the same clock_in are one shift. - Overtime is time over 40 hours in one week (Monday to Sunday), paid at 1.5x the hourly rate. - Hours on a shift that starts on a holiday are paid at 2x and do not count toward the 40 hours. - Work in exact hours and minutes; round only the reported figures, to 2 decimals half-up. Write `out/payroll.json`: `{"gross_pay": {"<employee_id>": <pay>, ...}, "overtime_hours": {"<employee_id>": <hours>, ...}, "holiday_hours": {"<employee_id>": <hours>, ... only employees with holiday hours}, "total_gross": <sum of the rounded gross pay figures>}`. List every hourly employee who worked in `gross_pay` and `overtime_hours` (0 if none). ## How this run works - Work on your own: nobody will answer questions in this task, and writing to `ask/` counts against the run. - Write only under `out/`. Create `out/` if it is missing. Inputs are synthetic; don't fetch anything from the network. - Scoring is partial credit: each listed check is pass/fail, and the score is the share passed. Numbers are compared to within 0.005 unless the task says otherwise.

Turn about 120-200 clock punches for 9-13 workers into gross pay for a two-week period. Overtime is weekly rather than per fortnight, breaks are deducted only above 6 hours, overnight shifts belong to their start day, the clock re-sends some punches, holiday hours are paid double and kept out of the overtime count, and salaried staff are mixed in. Pooling the fortnight, skipping the break, or counting duplicates each changes someone's pay. Original benchmark task written for usecaserank.com (not based on a specific public post). Headless, offline run on a reproducible fixture. Each run's notes say how its cost was measured (estimates are marked).

Success criteria: gross_pay overtime holiday breaks_and_duplicates

Setup notes: Batch 20 case v01-hourly-payroll-overtime (offline, synthetic inputs, seed 3091329474). Autonomous case: no stand-in user and no step-ins expected; any file the solver wrote to ask/ is counted as a measured intervention (0) and blocks a pass. Prompt = TASK.md verbatim. Hidden key kept outside the solver's work dir. Scored with the case's scorer (python3 score.py WORKDIR KEYDIR, absolute paths); pass = every check true and no ask/ files. Tools: Read/Write/Edit/Glob/Grep/Bash, web disabled. Single run, no retries. 1-min load average at scoring 1.33 (8 cores). Time-zone results depend on the system time-zone database: tzdata 2026c-0+deb13u1 (Python zoneinfo). Claude Code's own reported cost for claude-haiku-5.5: $0.006087. Score: 4/4. Cost is an ESTIMATE: measured tokens x pricing.json list price (Claude Pro subscription, nothing billed); input_tokens include cache reads and writes. Single run.

Estimated cost List-price estimate; not actually billed.

Reproduce this run

  1. Use the use case prompt on the use case page.
  2. Same setup: Claude Haiku 5.5 (anthropic/claude-haiku-5.5, effort default (no --effort flag) · thinking on) via Claude Code 2.1.299 (headless -p), cloud.
  3. It counts as a success only if it meets every success criterion: gross_pay overtime holiday breaks_and_duplicates
  4. Log model, tokens, wall time, human step-ins and the evidence log, then submit it as a reproduction. A different model? Submit a head-to-head rerun.

The salaried employees E214 and E249 are excluded.\n\nChoices I made where the brief was open:\n- **Duplicates:** 5 repeated punches were dropped, keeping one row per employee and clock-in. In every case the repeat had the same clock-out, so the choice doesn't change any figure. This includes the `kiosk-resync` rows.\n- **Period:** all shifts start inside 2026-10-05 to 2026-10-18, so none were excluded.\n- **Holidays:** 2026-10-12 is the only holiday. Its hours are paid at 2x and kept out of the 40-hour count. Shifts starting on 10-11 that run past midnight stay on 10-11.\n- **Rounding:** gross pay and hours are rounded half-up to 2 decimals only in the output. `total_gross` is the sum of the rounded gross figures.\n- **Employees with no overtime:** `overtime_hours` lists every hourly employee who worked, with 0 where there was none.\n\n| Employee | Gross pay | Overtime hrs | Holiday hrs |\n|---|---|---|---|\n| E200 | 2400.01 | 4.68 | 9.43 |\n| E207 | 2123.24 | 0.22 | \u2014 |\n| E221 | 2420.50 | 2.88 | 10.55 |\n| E228 | 2274.95 | 0.00 | 9.50 |\n| E235 | 2554.00 | 15.05 | 6.17 |\n| E242 | 1530.61 | 7.55 | \u2014 |\n| E256 | 1993.13 | 0.00 | \u2014 |\n| E263 | 1584.85 | 0.00 | 9.55 |\n| E270 | 2733.71 | 4.77 | 5.97 |\n| E277 | 1124.45 | 0.00 | 7.98 |\n| E284 | 2332.84 | 0.00 | \u2014 |\n\nI did not check the output against an independent calculation, so the figures rest on one script run.
