Run Conway's Game of Life on a full-screen canvas grid with click-and-drag to toggle cells, plus play/pause, step, randomize, and clear controls.
thinking
The user wants me to build a single-page Conway's Game of Life web app with: 1. Full-screen canvas grid 2. Click-and-drag to toggle cells 3. Controls: play/pause, step, randomize, clear 4. Everything in one index.html file 5. No external resources Let me build a polished implementation.

The user wanted me to build a Conway's Game of Life single-page web app. I've written it to /tmp/ws/index.html with all the features requested. Let me verify the file was created correctly.

The file has been written successfully. Let me verify the content looks complete and correct by reading it back.
Done! `index.html` is ready at `/tmp/ws/index.html`. Here's what's included: **Features:** - **Full-screen canvas** with a subtle grid and cyan-colored alive cells - **Click-and-drag** to paint/erase cells (also works with touch) - **Play/Pause** — toggles continuous simulation - **Step** — advances one generation - **Random** — fills ~25% of cells randomly - **Clear** — wipes the board - **Keyboard shortcuts** — `Space` (play/pause), `N` (step), `R` (random), `C` (clear) - **Live stats** — generation counter and population count - **Toroidal wrapping** — edges wrap around - **HiDPI aware** — renders crisply on Retina displays - **Responsive** — adapts to window resize while preserving cell state No external resources or network calls — it runs fully offline in a single file.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Game of Life grid works: drag places cells, space/enter runs simulation (Gen counts up), but display is sparse and minimal.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
