What it is
A Python test lab where Jev plays Snake, coached by Claude. For developers exploring Jev's judgment on sequential decisions with a known optimal score.
How it uses Jev
Each move, code filters unsafe moves and withholds pocket moves. Jev chooses among safe moves given state and questions. Its probabilities pick the move; low confidence marks coin-flips.
Primitives:choice
Technique worth stealing
Use a coaching loop: Claude reads death digests and proposes config edits, improving Jev without changing its weights.
Try it
uv run python -m snake run --player jev --digest
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
