Automated README summary
Automatically summarized from the README on 21 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Rust CLI that sends a state and typed questions to TypeSafe AI's System One (Jev) API and prints calibrated decisions as JSON, for scripts, shell pipelines, and agent tool calls needing fast decisions without a full LLM workflow.
How it uses Jev
The user supplies a state plus questions (choice, noul, score) via stdin, JSON argument, file, or CLI flags. jeb sends them to the Jev model and returns per-question probabilities; with -d it prints only the top decision per question.
Primitives:choicescorenoul
Technique worth stealing
Wrap a non-generative decision model behind a CLI so scripts and agents get typed, calibrated answers instead of free text.
Try it
cargo install --path . ; export TYPESAFE_API_KEY=... ; jeb --state "..." --noul "q:..."
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.
