Summary
Exact prompt
# AIS collision risk: CPA, TCPA and alert levels `input.json` (synthetic; not for collision avoidance): `own` ship (`lat`, `lon`, `cog` degrees true, `sog` knots), `targets` (each `mmsi`, `lat`, `lon`, `cog`, `sog`), thresholds `cpa_danger_nm`, `cpa_caution_nm`, `tcpa_max_min`. Write `solve.py` (Python 3 standard library only); `python solve.py input.json answer.json` writes `answer.json` and `radar.svg`. Fresh inputs are used too. ## Rules 1. Skip a target (list its mmsi in `skipped`, ascending) if lat, lon, cog or sog is missing/null, sog >= 102.3 (AIS "not available"), or cog >= 360 (not available). Keep the rest in input order. 2. Local flat frame around own ship in nm: x = (lon - own lon) * 60 * cos(own lat), y = (lat - own lat) * 60. Velocity of a ship = (sog * sin(cog), sog * cos(cog)) knots. 3. Relative position r = target - own, relative velocity v = v_target - v_own. If |v|^2 < 1e-9, TCPA = 0. Otherwise TCPA (hours) = max(0, -(r . v) / |v|^2). CPA = |r + v * TCPA|. 4. `range_nm` = |r|, `bearing_deg` = atan2(x, y) mod 360 (true bearing from own ship), `tcpa_min` = TCPA * 60. 5. Level: `danger` if CPA <= cpa_danger and tcpa_min <= tcpa_max; else `caution` if CPA <= cpa_caution and tcpa_min <= tcpa_max; else `none`. 6. `alerts`: mmsi of danger then caution targets, each group sorted by tcpa_min then mmsi. Round range/CPA to 3 decimals, bearing to 1, tcpa_min to 2. ## Visual output: radar.svg Static, self-contained SVG (root `<svg>`, no scripts, images, links or external assets; renders headless) with an element `id="own-ship"` and one element `id="target-<mmsi>"` for every non-skipped target. The drawing itself is not graded. ## answer.json `{"targets": [{"mmsi", "range_nm", "bearing_deg", "cpa_nm", "tcpa_min", "level"}, ...], "skipped": [...], "alerts": [...]}` ## Scoring Hidden checks (partial credit; all must pass): `filtering`, `range_bearing`, `cpa_tcpa`, `levels_and_alerts`, `radar_svg_static` (radar.svg exists, follows the static rules, has `own-ship` and every `target-<mmsi>`), `fresh_run_1`, `fresh_run_2`. Tolerances: distances 0.002 nm, bearings 0.11, minutes 0.011 (fresh runs 0.011 for all numbers). 60-second limit per run.
AIS not-available sentinels (sog 102.3, cog 360), a stationary target, diverging targets with TCPA clamped to 0, longitude scaling, near-threshold crossing targets, and a two-key alert sort. Original benchmark task written for usecaserank.com. Headless, offline run on a reproducible fixture. Cost shown is a list-price API-equivalent estimate (run on a Google account via Antigravity CLI, not billed per token).
Benchmark code for comparing AI models, not navigation or safety software.
Success criteria: 1. filtering 2. range_bearing 3. cpa_tcpa 4. levels_and_alerts 5. radar_svg_static 6. fresh_run_1 7. fresh_run_2
Setup notes: Use Case Scout batch10 case k08-ais-cpa-tcpa (offline fixture). Prepared with batch10/prepare.sh on the shared box; only TASK.md + starting files went to the agent machine, hidden keys stayed on the box. Prompt = TASK.md verbatim. Flags: -p --model gemini-3.8-flash-medium --sandbox --dangerously-skip-permissions --disable-slash-commands --output-format stream-json, cwd=workdir. Scored on the box with `python score.py WORKDIR KEYDIR`. Single run, no retries, no human input. Visual output (radar.svg) rendered offline to PNG with google-chrome headless, network blocked, 1280x800 at ~3 s after load. Requested model gemini-3.8-flash-medium (effort medium); priced at the base model row gemini-3.8-flash (pricing.json, https://ai.google.dev/gemini-api/docs/pricing). Score: 7/7. Cost is an ESTIMATE: measured tokens x pricing.json list price (Google account, nothing billed per token); output_tokens include thinking tokens. Tool calls 24 (0 failed). 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: Gemini 3.8 Flash (google/gemini-3.8-flash, effort medium · thinking on) via
Antigravity CLI 1.4.5 (agy -p), cloud. - It counts as a success only if it meets every success criterion: 1. filtering 2. range_bearing 3. cpa_tcpa 4. levels_and_alerts 5. radar_svg_static 6. fresh_run_1 7. fresh_run_2
- 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.

Skipped targets have their MMSIs recorded in `skipped` (sorted ascending). Non-skipped targets are processed in their original input order.\n- **Kinematics & Calculations**:\n - Positions are projected into the local flat frame: $x = (\\text{lon} - \\text{own\\_lon}) \\cdot 60 \\cdot \\cos(\\text{own\\_lat})$, $y = (\\text{lat} - \\text{own\\_lat}) \\cdot 60$.\n - Ship velocities are calculated as $(sog \\cdot \\sin(cog), sog \\cdot \\cos(cog))$.\n - CPA and TCPA calculations account for $|v|^2 < 10^{-9}$ and receding targets ($TCPA = 0$).\n - Target bearing is computed as $\\text{atan2}(x, y) \\pmod{360}$.\n - Outputs are rounded to 3 decimals for `range_nm` and `cpa_nm`, 1 decimal for `bearing_deg`, and 2 decimals for `tcpa_min`.\n- **Alert Levels & Sorting**: Targets are classified into `danger`, `caution`, and `none` levels. MMSIs in `alerts` are grouped (`danger` then `caution`), with each group sorted by `tcpa_min` ascending and then by MMSI.\n- **Visual Output**: Generates [`radar.svg`](file:///home/bob/usecase-runs/agy-batch/out/gemini-3.8-flash-medium/k08/work/radar.svg), a static, self-contained SVG rendered with range rings, crosshairs, `id=\"own-ship\"`, and unique `id=\"target-<mmsi>\"` elements for all non-skipped targets.\n\n### Verification\n- Tested with `input.json`, producing valid [`answer.json`](file:///home/bob/usecase-runs/agy-batch/out/gemini-3.8-flash-medium/k08/work/answer.json) and [`radar.svg`](file:///home/bob/usecase-runs/agy-batch/out/gemini-3.8-flash-medium/k08/work/radar.svg).\n- Verified edge cases including stationary/co-moving targets ($|v|^2 < 10^{-9}$), custom output directories, missing fields, and strict XML/SVG element ID assertions.\n", "duration_seconds": 234.434625621, "num_turns": 1, "usage": {"input_tokens": 148615, "output_tokens": 42934, "thinking_tokens": 34186, "cache_read_tokens": 1032123, "total_tokens": 191549}}}
