Summary
Exact prompt
# Animate a row of pendulums, each swinging at its own true period, in one self-contained HTML file Make a small animated scene: a pendulum wave. Write one file, `out/scene.html`, that works opened straight from disk with no network access. `spec.json` gives the page title, the stage size and the scene parameters. **Looks are not scored**: the page is opened in a headless browser (800x600 window, UTC time zone, network blocked) and checked by objective tests only. ## Scene contract - Draw the scene on one `<canvas>` or `<svg>` stage of `width` x `height` CSS pixels (spec.json), visible on load, with `<title>` containing spec.json `title`. - Animate continuously from load (`requestAnimationFrame` or timers); no click is needed unless stated below. - Expose `window.sceneState()`, returning the scene's current state in stage pixel coordinates (origin top-left of the stage): `{pendulums: [{name, angle_deg, pivot: {x, y}, bob: {x, y}}, ...]}`. Extra fields are fine. It must describe what is actually drawn. - Each pendulum in spec.json has a `length_m`. Its period T is the time for one full back-and-forth swing of an ideal small-angle pendulum of that length under `gravity` (m/s²); every pendulum swings with the same amplitude `amplitude_deg`. `sceneState()` must return the state at the moment it is called (work it out from `performance.now()`, don't return the last frame's numbers). - The page must log no errors and throw no exceptions. Keep the file at most 200,000 bytes; no external scripts, fonts, images or URLs (inline everything). ## Checks (partial credit = share passed) 1. `self_contained`: `out/scene.html` exists, is at most 200,000 bytes, references no http(s) or protocol-relative URL, and requests nothing from the network when opened. 2. `has_canvas_or_svg`: a visible `<canvas>` or `<svg>` of at least 300x200 CSS pixels is on the page. 3. `frames_change`: over 3 s, some later screenshot differs from the first in at least 0.1% of pixels, and at least 3 of 30 screenshots differ. 4. `swing_periods`: `sceneState().pendulums` names exactly the pendulums in spec.json, and over 3 s each pendulum's `angle_deg` stays within 2.5° of `amplitude_deg` × cos(2π t / T + φ) for some fixed φ, where t is `performance.now()` in seconds and T is the pendulum's period. 5. `bobs_on_strings`: in every sample, each bob is within 3 px of pivot + `length_m` × `px_per_m` × (sin θ, cos θ), θ = `angle_deg` (positive swings the bob to the right of the pivot, y grows downwards). 6. `no_console_errors`: no uncaught exception, `console.error` or browser error is logged during the run. ## 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.
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).
Success criteria: self_contained has_canvas_or_svg frames_change swing_periods bobs_on_strings no_console_errors
Setup notes: batch29 case h07-pendulum-wave (offline fixture). Prepared with batch29/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 `MEDIA_DIR=<dir> python3 score.py WORKDIR KEYDIR`. Single run, no retries, no human input. Gallery media (3 s headless-Chrome capture: poster.png + clip.mp4, network blocked) written to a fresh MEDIA_DIR by the scorer; SHA-256 in evidence.media. Autonomous case (seed 2944328201): no stand-in user; any ask/ file counts as an intervention and blocks a pass. 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: 6/6. Cost is an ESTIMATE: measured tokens x pricing.json list price (Google account, nothing billed per token); output_tokens include thinking tokens. Tool calls 29 (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 1.4.6 (agy -p), cloud. - It counts as a success only if it meets every success criterion: self_contained has_canvas_or_svg frames_change swing_periods bobs_on_strings no_console_errors
- 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.
