What it is
A Pi extension for coding agents that classifies incoming requests with Jev and routes each one to a configured provider/model. It ships config examples for TypeSafe, Cloudflare, Vercel, and OpenRouter, and is meant to be the only automatic router enabled.
How it uses Jev
The README says Jev classifies requests, but does not specify which typed questions are asked, what state is projected, or how the returned probabilities drive the routing policy in code. It only notes that src/classifier.ts holds transport adapters and response validation, and src/routing.ts holds the deterministic policy.
Technique worth stealing
Bounded text projection plus a deterministic routing policy kept separate from the Jev transport adapter.
Try it
pi install npm:pi-typesafe-router, then /typesafe-router setup typesafe, /typesafe-router doctor, /typesafe-router on
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.
