What it is
Advocaat is a small TypeScript client for asking AI questions about a dataset, powered by TypeSafe Jev. It returns probabilities, choices, and scores in one request, aimed at developers building type-safe data triage and classification.
How it uses Jev
Jev answers typed questions about a state: yes/no (ask.if, ask.chance), choices (ask.choice, ask.switch), and scores (ask.score). Results are returned under the same keys, with .choice, .chance, .ratio, and .confidence used directly in code.
Primitives:choicescorenoul
Technique worth stealing
Send several typed questions about the same state in one ask call instead of separate requests.
Try it
npx nypm i advocaat, set TYPESAFE_API_KEY, then call ask(state, { ... }).
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
