Real-time agent observability with a Jev-protocol judge.

Automated README summary

Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

Captures agent boundary events, checks them with code rules and typed semantic questions, and streams auditable recommendations to a live console. For developers exploring agent safety in a sandbox.

How it uses Jev

Each boundary event becomes a frozen snapshot. Code rules run first, then typed questions (Noul/Choice/Score) go to a judge over /v1/systemone. The judge's answer is recorded as an auditable recommendation; semantic signals never block or change it.

Primitives:choicescorenoul

Technique worth stealing

Frozen decision-time snapshots checked by code rules first, then typed semantic questions to a judge.

Try it

npm run server, open http://127.0.0.1:8787, press S1…S9 / F1.

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.
