Automated README summary
Automatically summarized from the README on 22 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
jevpipe is a Go CLI for Unix pipelines: it reads data from stdin, sends it to TypeSafe Jev's /v1/systemone endpoint, and writes the decoded answer as compact JSON to stdout, for shell users who want a typed decision as one pipeline step.
How it uses Jev
It builds a Jev question from stdin: a JSON object or array becomes the state, and for open questions leaf scalars become choice candidates; other stdin becomes the state with a noul question. Questions starting with is/does/has force noul. The decoded answer (model, usage, type, choice/confidence/probabilities or noul) is printed as JSON.
Primitives:choicenoul
Technique worth stealing
Map stdin shape to the primitive: JSON objects/arrays feed choice over leaf scalars; plain text or bare scalars feed noul.
Try it
Build with mise exec -E jev -- go build -o jev ., set JEV_KEY, then pipe data: cat record.json | jev "does this mention billing?"
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.
