Automated README summary
Automatically summarized from the README on 28 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A chess web app where you play against TypeSafe AI's Jev, Stockfish, or a hybrid of both. Built end to end in TypeScript.
How it uses Jev
Jev picks moves based on the board state, with six personalities and three difficulty levels. It also answers draw offers with a yes-or-no question. The Jev panel shows the move, confidence, and top candidates.
Primitives:choicenoul
Technique worth stealing
Hybrid mode: Stockfish shortlists five moves, Jev picks one by personality.

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.
