Devin Coach flags wasteful prompts before you send them, as Cognition ties usage limits to output

Coach checks drafts in Devin's input box and suggests a fix inline, such as planning first on a big open-ended build, dropping Ultra for a one-line change, or splitting bundled tasks into parallel child sessions; admins can set it to warn only (the default), require confirmation, or turn it off. It ships alongside Cognition's efficiency score, which estimates human engineering hours per session against cost and can automatically raise a user's spending limit (TokenPost).
