Summary
Exact prompt
# Choose next quarter's project portfolio Inputs: `projects.csv` (cost, engineering hours and estimated value of each candidate project, plus prerequisites) and `constraints.json` (budget, available hours, pairs that can't both be funded). Pick the set of projects that maximises total value. - Total cost must not exceed the budget, and total hours must not exceed the available hours. - A project can only be funded if all its prerequisites are funded too. - At most one project of each mutually exclusive pair may be funded. - Then answer one what-if: if the budget were cut by 10% (hours unchanged), what is the best total value achievable? Write `out/portfolio.json`: `{"selected": [<project ids, sorted>], "total_value": <n>, "total_cost": <n>, "total_hours": <n>, "value_if_budget_cut_10pct": <n>}`. ## 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.
Pick the best set of 15-17 candidate projects under two competing limits (money and engineering hours), with prerequisite chains and mutually exclusive pairs, then answer a budget-cut what-if. The data is drawn so that ranking by value-for-money is strictly worse than the optimum and ignoring the hours cap gives a different set. The hidden key is the unique exact optimum. Original benchmark task written for usecaserank.com (not based on a specific public post). Headless, offline run on a reproducible fixture. Cost shown is measured tokens x Venice list price and matches the amount Venice reported billing.
Success criteria: optimal_selection optimal_value cost_and_hours what_if_budget_cut
Setup notes: Batch 18 case t01-portfolio-under-budget (offline, synthetic inputs, seed 1184814210). 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 1.39 (8 cores). Time-zone results depend on the system time-zone database: tzdata 2026e-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. This is a re-run of an earlier run of the same case and model that was cut off by the nightly Venice budget (its per-run cap had been shrunk to fit the leftover allowance); that run was voided and never published. It is a new run, not a rescore. It ran at the normal $0.05 per-run cap. Score: 4/4. Cost is measured per-call tokens x Venice list price and matches the amount Venice reported billing. Input tokens include cached reads.

Reproduce this run
- Use the use case prompt on the use case page.
- Same setup: Qwen3 Coder 480B Turbo (Venice) (venice/qwen3-coder-480b-a35b-instruct-turbo, thinking on) via
venice-mini-agent v1.3.1, cloud. - It counts as a success only if it meets every success criterion: optimal_selection optimal_value cost_and_hours what_if_budget_cut
- 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.

Let me double-check the solution by verifying the constraints manually:\n\n1. **Budget constraint**: 626 \u2264 639 \u2713\n2. **Hours constraint**: 3931 \u2264 4092 \u2713\n3. **Prerequisites**:\n - PRJ-F requires PRJ-B (PRJ-B is selected) \u2713\n - PRJ-E requires PRJ-D (PRJ-D is not selected, but PRJ-E is not selected) \u2713\n - PRJ-K requires PRJ-I (both are selected) \u2713\n - PRJ-M requires PRJ-B (both are selected) \u2713\n4. **Mutually exclusive pairs**:\n - PRJ-G and PRJ-Q: Only PRJ-G is selected \u2713\n - PRJ-C and PRJ-O: Neither is selected \u2713\n\nThe solution looks correct. Here's my final summary:\n\nI've successfully solved the portfolio optimization problem by:\n\n1. Reading the project data from `projects.csv` and constraints from `constraints.json`\n2. Implementing a brute-force approach to find the optimal project selection that maximizes value while satisfying all constraints\n3. Handling prerequisites, mutually exclusive pairs, budget limits, and hour constraints\n4. Computing the impact of a 10% budget cut as requested\n5. Writing the results to `out/portfolio.json`\n\nThe optimal portfolio selects projects PRJ-B, PRJ-G, PRJ-I, PRJ-J, PRJ-K, and PRJ-M with a total value of 1078k USD, costing 626k USD and requiring 3931 hours. With a 10% budget cut, the best achievable value would be 1025k USD.",
