dbreunig/building-with-jev-skill

Agent skill for writing and debugging programs that call Jev.

Infra / SDKs / Integrations0.22Runner-up: Evaluation & Benchmarking
Automated README summary

Automatically summarized from the README on 29 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

An agent skill that helps developers write and improve programs calling Jev, TypeSafe's System One model. It covers question design, state structure, answer composition, confidence thresholds, and diagnosing failing questions. Targets jev-1.14 and jev-1.13.

How it uses Jev

The README does not describe specific decisions Jev makes or how its output is used in code; it only states the skill guides question design for Choice, Score, Noul, and Box, state preparation, and answer composition.

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.
