Use an editor agent for the small stuff, a terminal agent for the big stuff

Two tools, two jobs. In the editor, the agent is a very good autocomplete: rename this, extract that, fix the type error. In the terminal, the agent is a contractor: here is the task, come back when it builds.

The mistake is using either for the other. Terminal agents are slow for a one-line fix, and editor agents lose the thread on anything that touches more than three files.
