Automated README summary
Automatically summarized from the README on 3 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A self-contained handoff repository for building software with Jev, TypeSafe's System One model. It bundles the typesafe-ai Codex skill, an offline TypeSafe documentation snapshot, and an email application build brief, intended for Codex agents.
How it uses Jev
The README does not describe specific decisions Jev makes, the state it consumes, or how results are used in code. It states Jev returns typed judgments and probabilities, and should choose, rank, score, classify, check evidence, or select a bounded next action, while ordinary code retains exact calculations, quotas, permissions, idempotency, durable job state, and external-write authorization.
Technique worth stealing
Treat Jev as a general typed-decision layer, not a browser-only model; keep exact calculations and authorization in ordinary code.
Try it
Read LLM-BOOTSTRAP.txt, AGENTS.md, docs/EMAIL-APPLICATION-BUILD-BRIEF.md, and skill/typesafe-ai/SKILL.md.
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.
