Automated README summary
Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A TypeScript library for chess move resolution, evaluation, persona opponents, and historic game classification, built on TypeSafe AI System One models. For developers building chess tools, analysis, or AI opponents.
How it uses Jev
Jev resolves natural language intents to legal moves via Choice, evaluates moves in parallel across tactical sharpness (Score), strategic theme (Choice), and king attack risk (Noul), selects persona moves via composite scoring, and classifies games into archetypes.
Primitives:choicescorenoul
Technique worth stealing
Use System One primitives to map natural language to verified legal moves, avoiding hallucinated coordinates.
Try it
npm install jev-chess; npm run demo or npm run serve
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.
