Executing Sequential Phase
Overview
Sequential phases use natural git-spice stacking in the main worktree.
Each task creates a branch with gs branch create, which automatically stacks on the current HEAD. No manual stacking operations needed.
Critical distinction: Sequential tasks BUILD ON each other. They need integration, not isolation.
When to Use
Use this skill when execute command encounters a phase marked "Sequential" in plan.md:
- ✅ Tasks must run in order (dependencies)
- ✅ Execute in existing
{runid}-mainworktree - ✅ Trust natural stacking (no manual
gs upstack onto) - ✅ Stay on task branches (don't switch to base between tasks)
Sequential phases never use worktrees. They share one workspace where tasks build cumulatively.
