Automated README summary
Automatically summarized from the README on 14 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A benchmark where LLMs play Snake. Each model response advances the game by one tick, and with the same seed the food spawns in the same order for every model, so runs are reproducible and comparable.
How it uses Jev
Jev is used via the System One format: the endpoint receives { model?, state, questions } and returns answers. The game sends the current board state and questions about the next move, then applies the returned choice to advance the snake.
Primitives:choice
Technique worth stealing
Same seed ensures identical food sequence for all models, making runs reproducible and comparable.

Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
