What problem does it solve? Manually setting up a new development phase means editing multiple planning files consistently — the master PLAN.md, a phase plan file, a backlog file, and the archive — which is error-prone and easy to forget. This Skill automates the entire scaffolding process in one command. ## Core Features & Use Cases - Automatic Phase Numbering: Reads the Status Overview table in PLAN.md to determine the next phase number. - Multi-File Scaffolding: Creates the phase plan file, backlog file, and archive section, and updates PLAN.md and the current-phase config in one pass. - Confirmation Preview: Shows a draft of all changes and waits for user confirmation before writing any files. - Use Case: You finished Phase 2 of your project and want to start "API Integration" targeting 2026-09-01. Run the command and the Skill creates phase_3_api-integration.md, phase_3_backlog.md, updates PLAN.md, and sets the current phase. ## Quick Start Ask the AI to add a new phase called "API Integration" with target date 2026-09-01 to the project plan.
