How it works

Reads, edits, runs, verifies.

Coder works the way a careful engineer does: read the code first, plan the change, make the edit, run the build, and verify the result, looping until the task is actually done, not just suggested.

Permission modes decide how much of that loop runs without asking, from read-only plan to fully autonomous yolo.
