Automated README summary
Automatically summarized from the README on 14 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An unofficial community skill that teaches coding agents to design for TypeSafe Jev, a System One model. It provides typed decision patterns and links to 150+ community projects, sorted by shape, with code sketches. Installs in Claude Code, Codex, Antigravity CLI, Muse, and Muse Code.
How it uses Jev
Jev takes content and typed questions (Choice, Score, Noul) and returns a value with calibrated probability in 100-200 ms. The skill helps agents design these questions and use the results in code, such as routing tickets or grading pull requests.

Technique worth stealing
Designing typed questions with calibrated confidence for System One models.

Install via plugin marketplace for your agent, e.g., claude plugin marketplace add aaddrick/building-with-typesafe-jev.
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.
