Start with one project
Open Neovim in the chosen project directory. Inspect the current diff before asking an assistant to edit. Record the files it may change; existing unsaved or uncommitted work remains protected. A terminal pane is a place to run commands, not permission to run every suggested command.
Move between editor and process
Neovim has an embedded terminal. Use :terminal to start a shell buffer and Ctrl-\ Ctrl-N to return to Normal mode. Keep the editor and a test process in separate splits when that helps review. Check the working directory before commands that write files.
A CLI assistant is a separate process with its own login, permissions and quota. Use an explicitly selected account. Subscription CLI sessions and API-key calls have different accounting; never silently switch between them after a failure.
Finish with a visible handoff
Read the changed diff, run the relevant bounded checks, then capture their exit status and the artifact being reviewed. Describe what was checked and what still needs a native environment. The linked handoff guide defines this evidence boundary; the Harness guide explains how an orchestrator can keep it across jobs.
