Automated README summary
Automatically summarized from the README on 3 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Jev One is a JavaScript library for building stateful applications around TypeSafe AI's Jev, a model that answers by pointing to choices you supply. It carries observations into the next decision until an objective is verified or a limit is reached.
How it uses Jev
Jev selects from vocabularies of words, numbers, actions, or tools. Your code validates and applies the chosen entry, observes the real change, and feeds it back as context. The runtime loops until a success predicate verifies or a limit stops it.
Primitives:choicescore
Technique worth stealing
Rebuild legal actions from actual state each turn, so Jev's choices stay grounded in the observed world.
Try it
git clone, npm ci, npm run build, set AI_GATEWAY_API_KEY, then node examples/quick-start.js
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.
