Summary
Exact prompt
# Share out last week's tip pool Inputs: `shifts.csv` (who worked, in which role, for how many hours, per day), `tips.csv` (tips taken per day, cash or card) and `tip-policy.json`. Work out each person's tips for the week 2026-10-12 to 2026-10-18. - The pool is settled separately for each day, using only that day's tips and shifts. - Card tips are reduced by the card processing fee (`card_fee_pct`) before anything else; cash tips are not. - From each day's pool, `bar_share_pct` percent goes to the bartenders who worked that day, split by their hours that day. - The rest of the day's pool is split among servers and bussers in proportion to hours x role points (`points` in the policy). Managers take no tips. - Work exactly; round only the reported figures, to 2 decimals half-up. Write `out/tips.json`: `{"tips": {"<staff_id>": <week total>, ...}, "bar_total": <week total paid to bartenders>, "fees_deducted": <card fees for the week>}`. List everyone who received tips. ## 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.
Split a week of a restaurant's cash and card tips among staff from the shift log. The pool is settled day by day, card tips lose the processing fee first, the bar takes a fixed share split by bartender hours, the rest is shared by hours weighted by role points, and managers get nothing. Pooling the whole week, skipping the card fee or paying managers each changes someone's tips. 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: daily_pool card_fee bar_tipout points_no_managers
Setup notes: Batch 22 case x04-restaurant-tip-pool (offline, synthetic inputs, seed 186463014). 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 0.82 (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: $0.004395. 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.

Twelve staff received tips, and the managers (T32, T33) take none.\n\n```json\n{\n \"tips\": {\"T20\": 990.88, \"T21\": 863.56, \"T22\": 1408.39, \"T23\": 442.85, \"T24\": 276.55, \"T25\": 851.34, \"T26\": 330.58, \"T27\": 403.12, \"T28\": 270.6, \"T29\": 403.99, \"T30\": 181.6, \"T31\": 210.48},\n \"bar_total\": 796.08,\n \"fees_deducted\": 122.39\n}\n```\n\nHow I computed it:\n- **Card fee:** 2.5% of each day's card tips, deducted before the split. Cash is not charged. The weekly total is 122.38825, reported as 122.39.\n- **Bar share:** 12% of each day's net pool goes to that day's bartenders, split by hours that day.\n- **Floor share:** the remaining 88% goes to servers and bussers in proportion to hours \u00d7 points (server 1.0, busser 0.6). Managers and bartenders get nothing from this part, since bartenders have 0 floor points.\n- **Rounding:** all arithmetic used exact decimals, and only the final reported figures were rounded to 2 decimals, half-up.\n\nAs a cross-check, the rounded per-person amounts sum to 6633.94 against an exact net pool of 6633.96. The 0.02 gap is rounding across twelve entries. The bar total of 796.08 is 12% of the net pool, rounded half-up from 796.075.\n\nThe calculation script is in `/tmp/tipcalc/calc.py`, outside `out/`. Nothing was written to `ask/`.",
