Automated README summary
Automatically summarized from the README on 25 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Claude Code-native kit for building System-One decision layers on TypeSafe's Jev model. It provides subagents, a skill, a thin client, worked QuestionSets, and calibration tools for developers integrating Jev into their code.
How it uses Jev
Jev answers typed Choice/Score/Noul questions on a given state, returning calibrated probabilities. Code uses these results to make decisions, e.g., routing tickets based on team choice and refund probability. The kit includes a client and tools to measure thresholds.
Primitives:choicescorenoul
Technique worth stealing
Use Jev as a cheap, fast referee for multiple-choice judgments, not for text generation or arithmetic.
Try it
git clone, set TYPESAFE_API_KEY, run ./setup.sh, then use the ticket_triage example.
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.
