Typed decisions in Claude Code: adds $.jev over TypeSafe's Jev, through OpenRouter, Vercel AI Gateway, Cloudflare Workers AI, LiteLLM or the TypeSafe API.
discern
doeixd · SDK & Decision Frameworks
A semantic control-flow library for Effect: Jev's `Choice` / `Noul` / `Score` answers become typed branches. Thresholds are caller-supplied, and an answer below them takes an explicit `Uncertain` branch the compiler forces you to handle rather than being rounded up to the top label. Procedure routing filters candidates with deterministic predicates first and skips the model call entirely when one candidate survives.
