Is this compatible with standard git workflows?

Yes, it uses git-spice for branch management, which is compatible with standard git but provides enhanced tools for handling stacked PRs and branches.

What happens if a test fails during execution?

The skill includes a quality gate that validates the exit codes of tests, linting, and builds; if any step fails, the orchestration halts to allow for manual correction before proceeding.

How does the skill prevent implementing code outside the current phase?

It injects strict Phase Boundaries into subagent instructions, explicitly listing what must be implemented and what must be ignored to prevent scope creep.

What is natural stacking in this skill?

Natural stacking refers to the use of git-spice's branch creation which automatically stacks the new branch on the current HEAD, creating a linear dependency chain without manual upstack commands.

Why does this skill use a single worktree instead of many?

Sequential tasks are cumulative and rely on the integration of previous steps. A shared worktree ensures that dependencies and environment state are preserved across the entire phase.

Productivity & Workflow

Automates the execution of dependent coding tasks using natural git stacking and continuous workspace integration.

The Sequential Phase Executor is a specialized skill designed for Claude Code to manage complex development workflows where tasks must be performed in a specific order. By leveraging the natural stacking capabilities of git-spice, it ensures that each successive task builds directly upon the previous one's state within a shared worktree. This approach eliminates the need for manual branch management or upstacking, providing a seamless integration environment for features with high internal dependencies. It includes rigorous phase boundary enforcement to prevent scope creep and automated quality gates to ensure every commit in the stack is stable and verified.
