EVALUATION

2/5 partial

Snake is just a single green dot that doesn't grow a tail; arrow keys move it but score stays 0 and no game-over/restart seen.

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.
