What it is
guideme sends a question and your state to TypeSafe Jev and returns the answer as a normal TypeScript value: a boolean, one of your option keys, or one of your level keys. For programs that decide about text or data.
How it uses Jev
You build a Guide, define choices with choice(), levels with levels(), and ask with noul(), choose(), or score(). Jev returns calibrated probabilities; guideme turns them into a boolean, an option key, or a level key using thresholds, which your code acts on with if, switch, or comparison.
Primitives:choicescorenoul
Technique worth stealing
Use choice() and levels() descriptors to get exhaustive switch and ordered level comparisons instead of comparing keys.
Try it
npm install @guideme/sdk @opentelemetry/api (after first release); set TYPESAFE_API_KEY.
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.
