Summary
Exact prompt
# Work out a multi-leg trip itinerary across time zones Input: `itinerary.json`, a list of flight legs in travel order. Each leg has a local departure time (`depart_local`, wall-clock time at the departure airport), the departure and arrival time zones (IANA names) and the block time in minutes. Rules: - Arrival time = departure instant + duration_min, written as wall-clock time in the arrival airport's zone, format `YYYY-MM-DDTHH:MM`. - Use the real time-zone rules for the travel dates, including daylight-saving changes. - Layover = minutes from a leg's arrival to the next leg's departure (real elapsed minutes). - A connection is tight when its layover is under 60 minutes. - total_elapsed_min = real minutes from the first departure to the last arrival. - date_change_legs = the legs whose local arrival date differs from their local departure date, in travel order. Write `out/itinerary.json`: `{"arrivals": {"<leg>": "<YYYY-MM-DDTHH:MM>", ...}, "layovers_min": {"<leg>": <int>, ...}, "tight": [<leg>, ...], "total_elapsed_min": <int>, "date_change_legs": [<leg>, ...]}` `layovers_min` and `tight` are keyed by the leg that arrives before the connection (every leg except the last), and `tight` is in travel order. ## 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 4-6 flight legs given in local departure times and block minutes into local arrival times, layovers, tight-connection flags, total trip time and date-change legs. The travel window spans the late-October and early-November daylight-saving changes, and routes include half-hour and 45-minute offset zones. Departures that fall on ambiguous or skipped local times are redrawn. Original benchmark task written for usecaserank.com (not based on a specific public post). Headless, offline run on a reproducible fixture. Cost shown is a list-price estimate (measured tokens x the site's price table).
Success criteria: arrival_local_times dst_rules_applied layover_minutes tight_connections total_elapsed date_change_legs
Setup notes: Batch 16 case r02-timezone-itinerary (offline, synthetic inputs, seed 2415410439). Autonomous case: no stand-in user and the agent never needs to check with the user; 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 on the box with the case's scorer; pass = every check true and no ask/ files. Tools: list_files/read_file/write_file/run_shell (venice-mini-agent v1.3), web disabled. Single run, no retries. 1-min load average at scoring 1.62 (8 cores). Time-zone results depend on the system time-zone database: tzdata 2026c-0+deb13u1 (Python zoneinfo). Harness: venice-mini-agent v1.3.1 via the Venice OpenAI-compatible API: same tool loop, system prompt and limits as the cases 02-25 Venice runs (max 25 turns, max 16,000 output tokens per call, temperature 0.2, Venice system prompt and web search off, per-run cost cap $0.05, thinking on (model default)). Same task text, work-dir layout and scorer as the Claude runs of this case. Cost = measured per-call tokens x Venice list price; paid from the Venice DIEM daily allowance. Harness: venice-mini-agent v1.3.1 via Venice OpenAI-compatible API (max 16,000 output tokens per call, $0.05 run cap). Score: 0/6. Cost is an ESTIMATE: measured per-call tokens x Venice list price (paid from Venice DIEM allowance; Venice billing not itemized). input_tokens include cached reads. Single run.
Estimated cost List-price estimate; not actually billed.

Reproduce this run
- Use the use case prompt on the use case page.
- Same setup: Mistral Small 3.2 24B Instruct (Venice) (venice/mistral-small-3-2-24b-instruct, thinking on) via
venice-mini-agent v1.3.1, cloud. - It counts as a success only if it meets every success criterion: arrival_local_times dst_rules_applied layover_minutes tight_connections total_elapsed date_change_legs
- 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.
