Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A DuckDB extension that lets you ask a Jev question about every row of a table or Parquet file in SQL, returning real SQL types instead of text.
How it uses Jev
Each function takes a row's text plus a constant criteria literal that defines both the permitted answers and the column type. Jev picks from that set, and the typed result is used directly as an ENUM, DOUBLE, or STRUCT field in SQL.
Primitives:choicescorenoul
Technique worth stealing
Declare the answer set as a constant criteria literal so the result is typed by construction, not by validation.
Try it
CREATE SECRET (TYPE jev, API_KEY 'sk-...'); then call jev_choice, jev_score, jev_noul, or jev_ask.
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.
