SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema
How do I add a new development phase to a project plan?▼

Run the add-phase command with a phase name and optional target date, such as /add-phase "API Integration" 2026-09-01. The Skill shows a preview of all files it will create or modify, then scaffolds them after your confirmation.

What files does adding a project phase create?▼

It creates a phase plan file at context/plans/phase_N_slug.md, a backlog file at context/tasks/backlog/phase_N_backlog.md, appends a section to the archive, and adds a row and link to PLAN.md.

How is the phase number determined when adding a phase?▼

The Skill reads the Status Overview table in PLAN.md, finds the highest existing phase number, and increments it by one. If no phases exist yet, it starts at phase 1.

Does adding a phase change the current active phase?▼

Only if no phase is currently set. The Skill updates .claude/config/current-phase.md when the phase field is empty, but leaves it untouched if another phase is already In Progress.

What happens if I omit the target date for a phase?▼

The target date is optional. If no YYYY-MM-DD date pattern is found in the arguments, the Skill records the target as TBD, which you can edit later in the generated phase plan file.
