Summary
Exact prompt
You are a workday assistant on a mock calendar (no real accounts). Complete requests.md by editing calendar.json.
Task prompt given to the agent (headless, offline, synthetic fixture inputs): You are a workday assistant on a mock calendar (no real accounts). Complete requests.md by editing calendar.json. Inspired by https://agentusecases.ai (listing: 'Test AI browser agents on real workday tasks', natesnewsletter.substack.com) (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 computed from Venice list prices and per-call usage (not confirmed by Venice billing for this run).
Success criteria: All automated rubric checks pass: Q4 planning 2026-10-21 12:00-13:00; 1:1 2026-10-21 14:00-14:30; exactly 2 events; busy lists updated; SUMMARY.md written.
Setup notes: Harness: venice-mini-agent v1.1 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. cost_is_estimate=true: no Venice-reported billed amount recorded for this run. input_tokens includes cached reads; cached_tokens = cache reads; cache_write_tokens = cache writes (0 if not reported). Single run, no retries; scored automatically (5/5 checks). Runner notes: Adapted: browser agents on real accounts replaced by a mock calendar JSON scheduling task. Single run, no retries. Same rubric/score.py as Claude runs. Web disabled.
Estimated cost List-price estimate; not actually billed.

Reproduce this run
- Use the use case prompt on the use case page.
- Same setup: DeepSeek V4.1 Flash (Venice) (venice/deepseek-v4-1-flash) via
venice-mini-agent v1.1, cloud. - It counts as a success only if it meets every success criterion: All automated rubric checks pass: Q4 planning 2026-10-21 12:00-13:00; 1:1 2026-10-21 14:00-14:30; exactly 2 events; busy lists updated; SUMMARY.md written.
- 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.

Next: bob 10:30-13:00 \u2229 priya 11:00-14:00 \u2229 marco 12:30-15:30 = 12:30-13:00, 30 min. bob 14:00-17:00 \u2229 priya 11:00-14:00 = nothing (14:00 boundary, zero). bob 14:00-17:00 \u2229 priya 15:30-17:00 = 15:30-17:00 \u2229 marco 12:30-15:30 = nothing.
