System Documentation

What problem does it solve?

It turns a rough MVP idea into a validated, properly structured phase plan, reducing the risk of building the wrong slice or an overly large “phase” that should be split.

Core Features & Use Cases

  • User-story-first phase planning: Prompts for a clean “As a / I want to / So that” user story using structured questions, ensuring the goal is clear and testable.
  • SPIDR splitting guardrail: Checks whether the story is too large and, when needed, walks through Spike/Paths/Interfaces/Data/Rules to help you split into multiple phases.
  • Roadmap MVP mode + delegation: Writes the phase as Mode: mvp and updates the phase Goal, then delegates to the phase planner so the plan is generated in MVP mode.

Quick Start

Run the command /gsd mvp-phase 2 after making sure phase 2 already exists in ROADMAP.md.
