TypeSafe releases a skill teaching Claude Code to use Jev
The skill sets the order docs→behaviour→judgments→one request→code decides, so agents stop asking one question per call and guessing field names, and is said to cut the bill by 12.2x.
this is pure f*cking gold TypeSafe released the skill that teaches Claude Code to build on Jev left alone, coding agents send Jev one question per call and guess the field names this skill fixes the order before a single line gets written: docs -> behaviour -> judgments -> one request -> code decides every rule in it, broken down on two pages: > the failure behind each of its 11 instructions > Choice, Noul or Score, picked in one glance > a prompt skeleton you paste straight into your agent 12.2x that's how far the bill drops when 13 questions share one call, measured in TypeSafe's cookbook one short file, and your agent stops paying for decisions it should batch
