Summary

Exact prompt

# Total an apiary group's honey harvest by site and hive after hive moves, corrections and a moisture rule Inputs: `sites.csv` (site_id, name), `hives.csv` (hive_id, start_site), `moves.csv` (hive_id, date, to_site) and `harvests.csv` (harvest_id, date, hive_id, frames, gross_kg, moisture_pct, corrects). The season's ledger is synthetic: every site, hive and beekeeper is invented, and the tare and moisture figures below are this group's own house rules. These rules are the group's; where `helper-note.txt` disagrees, the rules win. Rules: - Corrections: a harvest row whose corrects names another harvest_id replaces that row completely; the corrected row is ignored and the correction's own date, hive and figures are used. A blank corrects means an ordinary row. - Sites: a harvest counts at the site its hive stood at on the harvest date: the hive's start_site, changed by every move of that hive dated on or before the harvest date (a move counts from its own date). - Net honey: gross_kg minus 0.42 kg of tare for each frame, in kg. - Feed honey: a harvest whose moisture_pct is above 18.5 is set aside as feed honey; at 18.5 or below its net honey is sellable. - Top hive and jars: the top hive has the most sellable honey (on a tie, the lower hive_id); jars is the number of whole 340 g jars the total sellable honey fills. - Write `out/harvest.json`: `{"sellable_kg_by_site": {"<site_id>": <kg>, ...}, "feed_kg_by_site": {"<site_id>": <kg>, ...}, "sellable_kg_by_hive": {"<hive_id>": <kg>, ...}, "top_hive": "<hive_id>", "jars": <whole number>}`. - Roll-ups: Sites in sites.csv with no sellable honey are left out. Sites in sites.csv with no feed honey are left out. Hives in hives.csv with no sellable honey are left out. ## 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.

Work out a synthetic beekeeping group's season from a harvest ledger: net honey is gross weight minus a stated tare per frame, each harvest counts at the site the hive stood at on that date (hives are moved between sites, and a move counts from its own date), correction rows replace the rows they correct, and honey over a stated moisture limit is set aside as feed honey. Report sellable and feed honey per site, sellable honey per hive, the top hive and the jar count. The prompt says sites and hives with nothing to report are left out, not listed at 0. A helper's note gets the tare, move and roll-up rules wrong. 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: sellable_by_site feed_by_site sellable_by_hive top_hive jars

Setup notes: Batch 41 case tp02-apiary-honey-harvest-ledger (offline, synthetic inputs, seed 949217541). 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 0.27 (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-sonnet-5.5: $0.049532. Score: 5/5. 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 Sonnet 5.5 (anthropic/claude-sonnet-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: sellable_by_site feed_by_site sellable_by_hive top_hive jars
  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.
