Dev Workflow

Full development lifecycle: workspace setup → plan execution → branch completion.

Mode Selection

Starting new feature needing isolation?       → WORKTREE SETUP mode
Have a written plan to execute?               → EXECUTE PLAN mode
Implementation done, need to ship?            → FINISH BRANCH mode

WORKTREE SETUP MODE

Create an isolated git workspace before multi-task development

Always set up before: executing plans, subagent-driven development, any work that shouldn't touch main/master.
