Guide: build agents where the big model writes, Jev decides, code validates
blaizedsouza · x · 2026-09-25
Developer cyrilXBT shares the guide he wishes existed for his first agent: instead of calling a frontier model for every route, yes/no, and tool choice, structure it as "big model writes, Jev decides, your code makes the final call." Decisions come back typed with confidence scores, making the agent faster, cheaper, and easier to debug.
