Workflow

Step 0: Exit Plan Mode

If you are in plan mode: Call ExitPlanMode() immediately. Do not explore files, do not read code, do not create plans. Wait for user approval then continue with Step 3.

Step 1: Prepare Worktree

Check session context for worktree parameters:

• identifier: TASK-NNN or FEATURE-slug
• title: Feature/task title

If not already in worktree:

If no identifier create a new identifier yourself in the format FEATURE-slug. Otherwise, use the identifier provided.
