I GAVE CLAUDE A BRAIN THAT DECIDES HOW HARD TO THINK Not per session. Per step. Jev is a classifier that scores each move 0 to 1. Claude Opus 5 shifts between LOW, MEDIUM, and HIGH reasoning mid-run. Reading files. LOW. Twelve steps in a row. Then it cross-references modules. LOW to MEDIUM. Final analysis across 1,176 lines. MEDIUM to HIGH. 6 real bugs. 14 steps. $0.38. 160 lines of python, no framework, and one API beta you've never seen in a demo.
