Jev-verify 模式：只做合约校验不写内容

we've been using Claude f*cking wrong on contracts too your $200/mo model writes a function AND grades whether it matches the spec. then it writes a second prompt to grade the grading. three turns later you have a boolean back and 40 cents burned. Jev flips that too. it's a mode of Jev that cannot write a single word. you give it a response and the contract it was supposed to satisfy, it gives back one of three things: -> pass or fail -> which clause broke -> the exact span that broke it each with a confidence, so your code knows whether to retry or raise. that's the whole mode. -> 40 to 300 milliseconds per check -> $0.018 per million input tokens -> output is free -> 10,000 verifications for around $0.18. that's not because Jev knows your contract better than Claude. it's because nobody asked it to write the next thing. > let Claude write. > let Jev tell you if the write holds. > let code decide what to do with the verdict. the catch: schema only, no free-form rules, and the span index is chars not lines. how to wire Jev-verify in front of every tool call + the exact contract format in the article below
