Automated README summary
Automatically summarized from the README on 18 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Ruby gem that provides convenient access to the TypeSafe System One API, allowing Ruby applications to send state and typed questions to Jev and receive structured answers with probabilities and confidence.
How it uses Jev
Jev answers typed questions (choice, score, noul) about a given state. The client sends these questions and returns probabilities and confidence, which code uses to decide whether to act automatically or escalate to a human.
Primitives:choicescorenoul
Technique worth stealing
Use confidence from Jev's answers to gate automatic decisions versus human review.
Try it
Install the gem, set TYPESAFE_API_KEY, and call client.system_one with state and questions.
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.
