The author uses Jev as the decision layer and Opus as the reasoning layer to pick project notes, route simple tasks, choose recovery paths when tools fail, and run targeted checks, reporting roughly 80% lower cost and execution time.
jev + opus 5.5... i genuinely don't understand why more people aren't building this yet in my workflow, it cut both cost and execution time by ~80%. one of the best ways to use opus → select the right project notes before loading context → route simple tasks to a faster worker → choose a recovery path when a tool fails → run targeted checks before the full test suite opus handles the difficult reasoning. jev chooses between the options the harness prepares and validates i explain how to build this decision layer in the article below:
