Automated README summary
Automatically summarized from the README on 28 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A personal playground for trying out TypeSafe AI's Jev evaluation model with fictional data. It is used to check prompt (state and questions) writing, answer confidence, latency, and cost before integrating into production.
How it uses Jev
Jev is used to run scenarios defined in YAML files. The state and questions are provided, and Jev returns typed answers: choice, score, or noul. The results are aggregated and displayed. The README does not specify how the answers are used in code beyond aggregation.

Technique worth stealing
Using fictional data to test prompt writing, confidence, latency, and cost before production integration.

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.
