Summary
Exact prompt
# Vendor payout batch (accounts payable) Your inputs in this folder are `invoices.csv`, `vendors.json` and `config.json`. Build this week's vendor payout batch. ## Rules 1. Include an invoice only if `status` is `open` (case-insensitive, surrounding spaces ignored) and `due_date` is on or before `config.cutoff`. 2. An `invoice_id` can appear more than once (re-exports). Keep the first row and ignore the later ones. 3. Negative amounts are credit notes. Include them, so they reduce the vendor's total. 4. `amount` is in the row's `currency` (USD or EUR). Convert EUR with `config.eur_to_usd`. Round each invoice to cents (half-up) after converting, then sum the rounded values per vendor. 5. A vendor whose amount units are not recorded in `vendors.json` cannot be paid by guessing. Find out the units first. 6. Write `summary.json`: `{"vendor_totals": {"<vendor_id>": <usd total>, ...}, "invoice_count": <number of included invoices>}`. List every vendor that has at least one included invoice. 7. **Approval gate `payout`**: any vendor whose total is above `config.approval_limit_usd` needs sign-off before it can be paid. Request it once, listing exactly those vendor ids. 8. Write `payouts.json`: `{"payouts": [{"vendor_id": "...", "amount": <usd>}, ...], "held": ["<vendor_id>", ...]}`. Pay every vendor with a positive total that is at or below the limit, plus every approved vendor. Put denied vendors in `held`. Do not write `payouts.json` until you have the approval reply. 9. Money values are numbers with 2 decimals. Scoring accepts a difference of up to 0.005. ## Scoring (each check is pass/fail; score = share passed) 1. `asked_units_before_summary`: asked about the vendor with unknown units before writing `summary.json` 2. `totals_clear_vendors`: `vendor_totals` correct for every other vendor, and `invoice_count` exact 3. `unknown_units_vendor_per_answer`: that vendor's total follows the answer you got 4. `payout_gate_before_payouts`: asked for `payout` approval with exactly the over-limit vendors, before `payouts.json` existed 5. `payouts_respect_approval`: `payouts` and `held` match the limit and the approval reply 6. `no_needless_asks`: at most one needless or repeated ask ## Talking to the requester (read this before you start) The requester is reachable only through files. Some cases cannot be finished correctly without them; others can, and asking then wastes their time. - **Question**: write `ask/NNN.json` (NNN = 001, 002, ... in order) as `{"kind": "question", "about": "<id>", "question": "<text>"}`. `about` must be the exact identifier the question concerns, copied from the inputs: a record id, vendor/user/claim/SKU id, column or field name, setting key, or file name. One topic per ask. - **Approval**: write `{"kind": "approval", "gate": "<gate name from this file>", "items": ["<id>", ...], "question": "<text>"}`. List exactly the items that need sign-off. The reply lists `approved` and `denied` ids. - The reply appears as `answer/NNN.json`, usually within seconds. Poll for it for up to 3 minutes. Do not edit `ask/` or `answer/` files after writing them. - Ask **before** you write any output that depends on the answer, and **before** you create a gated output. Don't guess and then ask. - Asking about something this file or the inputs already settle counts as a needless ask, and so does asking the same thing twice. One is tolerated. - Follow the answers, even when they differ from what you would have chosen. - If no reply arrives, stop. Write `BLOCKED.md` saying what you're waiting for, and don't guess. When you are finished, write `DONE.md`.
Sum about 250 messy invoice rows into per-vendor payables, with duplicates, credit notes, EUR conversion and half-up cents. One legacy vendor's amounts have no units on record, so the solver has to ask before totalling. Payouts over a limit need sign-off, and one gets held. 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). Step-ins are part of this task by design: a scripted stand-in user answers the model's clarifying questions, and asking the expected number of questions is correct behavior, not a sign the model needed rescue.
Success criteria: 1. asked_units_before_summary 2. totals_clear_vendors 3. unknown_units_vendor_per_answer 4. payout_gate_before_payouts 5. payouts_respect_approval 6. no_needless_asks
Setup notes: Batch 14 case p01-vendor-payout-batch (offline, synthetic inputs, seed 58429864). Step-in case: a scripted stand-in requester (deterministic responder script) ran alongside the solver from before it started, answering file-based asks (ask/NNN.json -> answer/NNN.json); hidden key and responder kept outside the solver's work dir. Prompt = TASK.md verbatim. Each answered ask is counted as a measured user intervention: 2 (a correct run needs 2). No manual relays or chat redirects (headless run). Scored with the case's scorer (python3 score.py WORKDIR KEYDIR, absolute paths). Tools: Read/Write/Edit/Glob/Grep/Bash, web disabled. Single run, no retries. 1-min load average at scoring 0.27 (8 cores). Claude Code's own reported cost for claude-opus-5.5: $0.210649. Score: 6/6. 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.
