Automated README summary
Automatically summarized from the README on 26 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Go binary that connects AI agents like Claude Code, Claude Desktop, Codex, Hermes and pi to TypeSafe's Jev and other System One models, returning probabilities instead of prose for quick judgment calls.
How it uses Jev
The agent sends a state string plus typed questions (noul, choice, score) via the evaluate tool; Jev returns a probability per answer, which the agent uses in if statements or threshold comparisons. Setup registers evaluate with each detected client.
Primitives:choicescorenoul
Technique worth stealing
Ask narrow typed questions with named options so the agent gets probabilities it can branch on, not text to parse.
Try it
curl -fsSL .../install.sh | sh, then TYPESAFE_API_KEY=your-key evaluate setup mcp
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.
