The README opens with

jev-code - a coding agent and TypeScript SDK built on Jev, the decision-only model from typesafe.ai

jev-code is a TypeScript library first. Your code lists the options and runs the effects. Jev only picks one option. The library gives you decision sessions, typed routers, DecisionProgram values, and bounded tree building. The CLI below is built on the same pieces.

See the SDK guide and the runnable router and dependency-tree examples. Import from the package root only.
