What it is
A VGI worker for DuckDB that exposes TypeSafe System One questions — choice, noul, and score — as table functions, so SQL users can classify, judge, and score rows in a LATERAL join or WHERE clause.
How it uses Jev
Each row's state (a string, struct, list, map, or whole row) is sent to TypeSafe with named questions; Jev returns typed columns — choice with confidence and probabilities, noul as a probability, score with confidence and probabilities — plus per-row token usage. Results are used directly in SQL, e.g. filtering on confidence.
Primitives:choicenoulscore
Technique worth stealing
Judge once, then split rows on confidence: auto-route the confident ones and keep the rest for a human.
Try it
INSTALL vgi FROM community; LOAD vgi; ATTACH 'typesafe' (TYPE vgi, LOCATION 'uvx --from git+https://github.com/Query-farm/vgi-typesafe vgi-typesafe');
