The user wants a Conway's Game of Life single-page app. Let me build it into index.html.

Done. I created `/workspace/index.html` — a self-contained Conway's Game of Life. **Features:** - **Full-screen canvas grid** with a glider seeded to get you started - **Click & drag** to draw cells (drag sets all cells to the same state as the first cell touched — erases if you start on a live cell, draws if you start on a dead cell), with pointer capture so dragging outside doesn't break - **Controls:** Play/Pause, Step, Randomize (25% fill), Clear - **Generation counter** in the toolbar - **Keyboard:** Space toggles play/pause **Implementation details:** - All CSS/JS inline, no external resources, fully sandboxed - Toroidal (wrap-around) grid so patterns loop off edges - DPR-aware canvas for crisp cells on HiDPI displays - Efficient row-based `Uint8Array` grid with neighbor counting - Re-draws every animation frame so edits and state stay in sync Open it in a browser to run.
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 runs and evolves generations, but the pattern stays tiny/sparse and clicks/drags don't visibly add cells.
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.
