Jev engineers just released a PDF on building a Jev harness for coding agents this is a clean blueprint for making agents faster, cheaper and easier to control. 1. jev picks which files, model and route to use 2. the frontier model only handles the work that actually needs generation 3. code keeps control over tests, approvals and execution the result: smaller contexts, fewer wasted llm calls and a coding loop you can actually inspect.
