Automated README summary
Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A set of commented TypeScript demos for QA and SDET engineers, walking through Jev, TypeSafe AI's System One model, called through Vercel AI Gateway with the AI SDK's experimental_evaluate.
How it uses Jev
In the triage demo, 8 failed CI tests are the state; Jev answers root cause (Choice), release impact (Score) and whether a retry will pass (Noul). Code then routes each result to file bug, fix test, ping DevOps, auto-retry or human review.
Primitives:choicescorenoul
Technique worth stealing
Ask Jev for typed probabilities, then keep the routing decision in plain code.
Try it
npm install, add your key to .env, then npm run demo:hello
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.
