Summary
Exact prompt
# Work backward from a retirement budget: savings target, contributions and earliest retirement age `input.json` describes a saver (synthetic numbers). Write `solve.py` (Python 3 standard library only) so that `python solve.py input.json answer.json` computes how much they need, how much they must save each year, and the earliest age they could retire. We re-run it on fresh inputs, so do not hard-code anything. ## Input `current_age`, `retire_age`, `end_age` (integers), `spend_today` (yearly spending in today's dollars), `inflation`, `return_pre` (yearly return before retirement, never 0), `return_post` (after), `current_savings`, `gross_income`, `actual_contribution` (what they save per year now), `part_time_income_today` (yearly part-time income in today's dollars), `part_time_years`. ## Rules 1. For a retirement age A, the first retirement year's spending is S = `spend_today * (1 + inflation) ** (A - current_age)`; spending in retirement year k (k = 0 .. end_age - A - 1) is S * (1 + inflation) ** k. 2. Part-time variant: income in retirement year k is `part_time_income_today * (1 + inflation) ** (A - current_age + k)` for k < `part_time_years`, else 0. The withdrawal is max(0, spending - income). 3. Withdrawals happen at the start of each retirement year. The **target** for age A is the sum over k of withdrawal_k / (1 + return_post) ** k (no part-time income), and **target_with_part_time** uses rule 2. 4. Saving: with m = A - current_age and g = (1 + return_pre) ** m, the projected savings at A with a level contribution C at the end of each year is `current_savings * g + C * (g - 1) / return_pre`. 5. `required_contribution` = the C that makes the projection equal the target for A = `retire_age`, but never below 0; the same with the part-time target gives `required_contribution_with_part_time`. `required_savings_rate` = required_contribution / gross_income (6 decimals). `projected_at_retire_age` = the projection with C = `actual_contribution`. 6. `earliest_retire_age` = the smallest integer A from current_age + 1 to end_age - 1 where the projection with `actual_contribution` >= the target for that A; `null` if none. `earliest_retire_age_with_part_time` does the same against the part-time target. 7. Round money to 2 decimals only when writing. ## Output `answer.json` keys: `target`, `target_with_part_time`, `required_contribution`, `required_contribution_with_part_time`, `required_savings_rate`, `projected_at_retire_age`, `earliest_retire_age`, `earliest_retire_age_with_part_time`. ## Scoring Hidden checks (partial credit = fraction passed; all must pass), money within 0.011, rate within 0.000001, ages exact: `savings_target`, `part_time_target`, `required_contributions`, `earliest_ages` on the given input; `fresh_run_1` and `fresh_run_2_edge_cases` (all keys; the second input has part-time income above spending and a small contribution) on fresh inputs. Each run has a 60-second limit.
Start-of-year withdrawals discounted at the post-retirement return, part-time income inflated from today and floored at zero withdrawals, end-of-year contribution annuity, and a per-age search where the target moves with the age. Cost-cap stop: the run hit its $0.05 cost cap ($0.051684 over 20 turns), so it counts as a fail. Its leftover output scored 6/6 on the scorer. Its leftover output scored 6/6 on the scorer. 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 pricing.json list price). Rescore note (Oct 23, 2026): re-scored from the saved work dir: the original scoring step failed to start (exit 127, scorer interpreter missing), so the first score was not a real result. Model output and measured data unchanged.
These are synthetic test cases for comparing AI models, not financial advice.
Success criteria: 1. savings_target 2. part_time_target 3. required_contributions 4. earliest_ages 5. fresh_run_1 6. fresh_run_2_edge_cases
Setup notes: Use Case Scout batch 9 case j04-reverse-retirement-plan (offline fixture). Prepared with batch9/prepare.sh; hidden key/tests kept outside the agent's work dir. Prompt = TASK.md verbatim. Scored with the scout's scorer: `python score.py WORKDIR KEYDIR`. Tools: list_files/read_file/write_file/run_shell (venice-mini-agent v1.3), web disabled. Single run, no retries. Harness: venice-mini-agent v1.3.1 (/workspace/usecase-runner/venice_agent2.py) via the Venice OpenAI-compatible API: same tool loop, system prompt and limits as the cases 02-25 Venice runs (max 25 turns, max_tokens 16000/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_prices.json list price; paid from the Venice DIEM daily allowance. Run ended early: run cost cap $0.05 reached. Cost-cap stop: the run hit its $0.05 cost cap ($0.051684 over 20 turns), so it counts as a fail. Its leftover output scored 6/6 on the scorer. Harness: venice-mini-agent v1.3.1 via Venice OpenAI-compatible API (16000 max tokens/call, $0.05 run cap). Score: 6/6. Cost is an ESTIMATE: measured per-call tokens x pricing.json 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: Kimi K2.5 (Venice) (venice/kimi-k2-5, thinking on) via
venice-mini-agent v1.3.1, cloud. - It counts as a success only if it meets every success criterion: 1. savings_target 2. part_time_target 3. required_contributions 4. earliest_ages 5. fresh_run_1 6. fresh_run_2_edge_cases
- 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.
