Automated README summary
Automatically summarized from the README on 4 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A TypeScript library of 248 focused recipes for JavaScript and TypeScript. It helps developers route messages, select evidence, review agent actions, and label model responses in agents, RAG, support, code review, and music applications.
How it uses Jev
Each recipe accepts your data, calls Jev through TypeSafe's System One API or an injected compatible client, and returns a structured decision. For example, route takes a support message and team descriptions and returns a team or a review outcome when uncertain. Your application decides what happens next.
Primitives:choicescorenoul
Technique worth stealing
Use one function call per decision, with explicit uncertainty handling and optional offline evaluation.
Try it
npm install jev-recipes, set TYPESAFE_API_KEY, then run a recipe like route.
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.
