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.

4 permission modes

planRead-only — explores and plans without making changes
defaultAsks before writes — safe for production codebases
autoAuto-approves file writes — fast iteration flow
yoloFull autonomy — runs commands without confirmation
