Sequential and parallel phases automatically inherit from the current base branch without manual intervention. Each new phase builds on completed work from previous phases, with the main worktree tracking the base and explicit verification steps confirming correct cross-phase inheritance across your stacked branches.

Phase stacking is the automatic dependency chain where each workflow phase inherits the work completed by prior phases. It prevents broken dependency chains by ensuring sequential phases build on previous outputs and parallel phases share the same base, eliminating manual base branch management.

Use explicit verification commands to check stack continuity and confirm correct base branch detection. Verification ensures each phase has inherited the expected work from previous phases and that the cross-phase chain maintains proper dependency relationships without gaps.

Yes. Parallel phases automatically inherit from the base branch established by sequential phases. Once a sequential phase completes, parallel phases spawn from that base, ensuring they build on the finished work rather than stale branches.

Failed base detection breaks the dependency chain, causing phases to inherit from incorrect or stale branches. The Skill provides verification steps to catch base detection issues early and prevent cascading failures across your stacked phases.

No. Phase inheritance is fully automatic—no manual branch management required. The system tracks base branches through the main worktree and applies inheritance rules automatically, with explicit verification as the only manual step needed to confirm correctness.
