What it is
A Pi extension for coding agents that keeps the Agent Skills catalog out of model requests and replaces it with one ranking tool backed by TypeSafe's Jev System One model, so skills load on demand.
How it uses Jev
Each enabled skill becomes its own Score question: the task goes in the shared state, and the skill's name and description go in that skill's instructions. Jev rates every skill on three ordered levels (0 unrelated, 1 adjacent, 2 directly applicable) and returns a probability-weighted position. Code applies the floor, sorts, and loads the winners.
Primitives:score
Technique worth stealing
Judge each skill as an independent Score question against shared task state, so no keyword prefilter can drop a skill first.
Try it
pi install git:github.com/safzanpirani/pi-jev-skill-picker, then /reload or start a new session.
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.
