building-with-jev skillA
building-with-jev is agent-read markdown (skill) from notque/vexjoy-agent: Write, compose, integrate, and improve programs that call Jev, TypeSafe's System One judgment model..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Building with Jev Jev reads one `state`, answers every question in the request independently and in parallel, and returns a probability distribution over answers you defined. A head cannot read another head's answer: parallel heads share evidence, not reasoning. For one state, maximize independent heads that can change a decision or action, subject to their token cost and the 64,000-token request budget; omit noise heads. Code owns control flow, arithmetic, policy, and every serial dependency; Jev owns the snap judgment. It does not reason in steps, count, do arithmetic, or generate text. Use this skill to design the questions, fit the state, compose answers in code, wire the call into a hook or script, and fix a call that answers wrong. …
