Exact prompt

Mock flight search (no real booking). flights.json lists available flights. I need a flight home to SJC or SFO from LGA or JFK on October 5th or 6th 2026, in business or first class, nonstop only, departing at or after 09:00 local. Choose the cheapest flight meeting all constraints. Write choice.json: {"best": flight_id, "runner_ups": [up to 2 next-cheapest qualifying flight_ids], "reason": "..."}.

Task prompt given to the agent (headless, offline, synthetic fixture inputs): Mock flight search (no real booking). flights.json lists available flights. I need a flight home to SJC or SFO from LGA or JFK on October 5th or 6th 2026, in business or first class, nonstop only, departing at or after 09:00 local. Choose the cheapest flight meeting all constraints. Write choice.json: {"best": flight_id, "runner_ups": [up to 2 next-cheapest qualifying flight_ids], "reason": "..."}. Inspired by https://x.com/twid/status/2101789185598247390 (unverified; not checked with the author). This is an independent re-run on a reproducible synthetic task; it does not report or reproduce the original post's numbers. Cost is real Venice spend (paid from DIEM credit), as reported by Venice.

Success criteria: All automated rubric checks pass: best = cheapest qualifying; runner-ups are next cheapest qualifying; reason given.

Setup notes: Harness: venice-mini-agent v1.2 via Venice OpenAI-compatible API. Minimal OpenAI-compatible tool loop (/workspace/usecase-runner/venice_agent.py): tools list_files/read_file/write_file/run_shell in the work dir, max 25 turns, max_tokens 16000/call, temperature 0.2, Venice system prompt and web search off, $0.08 per-run cost cap. Identical for all Venice models. Cost source: Venice /api/v1/models model_spec.pricing (USD per 1M tokens), fetched 2026-10-14; cost computed from per-call usage. Paid from Bob's DIEM daily allowance. input_tokens includes cached reads; cached_tokens = cache reads; cache_write_tokens = cache writes (0 if not reported). Single run, no retries; scored automatically (1/3 checks). Runner notes: Adapted: live flight search replaced by mock flights.json with one correct answer; no booking. Single run, no retries. Same rubric/score.py as Claude runs. Web disabled.
