the slow part of your agent is not the hard problem. the problems start after it does the same work several times. JEV DOESN'T WRITE. IT DECIDES. one auth refactor. 340 lines. 31 checks: keep this hunk, reject that file, stop or go again. claude code spent a full generation on each one. jev takes the diff and returns a score. 70-500ms. $0.042 per million in. no output text. output is free because there isn't any. 20-200x faster. 40-400x cheaper. the ceiling is only for loops that decide a lot and write a little.
