mani-aiml/jev-demos

One folder per demo of Jev, TypeSafe's System One model.

Automated README summary

Automatically summarized from the README on 19 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A collection of self-contained demos using Jev, TypeSafe's System One model, alongside other System One models. Each folder has its own README, requirements and keys; the code backs videos on The Agentic Enterprise.

How it uses Jev

The README does not specify which decisions Jev makes, on what state, or how results are used in code; it only names demo folders such as Jev fetching for Claude, Jev grading answers, Jev as a prompt-injection review gate, and Jev checking listing photos.

Try it

cd into a demo folder, create a venv, pip install -r requirements.txt, copy .env.example to .env and add that folder's keys.

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.
