What problem does it solve?
It helps you turn a phase idea into an MVP-ready plan by forcing a clear user story, checking whether the scope is too large, and writing consistent roadmap output for downstream planning.
Core Features & Use Cases
- Guided MVP-mode user story capture: Collects an “As a / I want to / So that” story via structured prompts to reduce ambiguity.
- SPIDR-based scope splitting: Checks whether the story is too big and, if needed, walks you through Spike/Paths/Interfaces/Data/Rules and offers to split into multiple phases.
- Roadmap conversion and delegation: Writes Mode: mvp and a reformatted Goal into the phase’s ROADMAP.md, then delegates to /gsd plan-phase <N> to continue planning with MVP mode.
Quick Start
Run gsd-mvp-phase with your phase number (for example, 2) so it captures the MVP user story, validates scope, updates ROADMAP.md with Mode and Goal, and then generates the plan via /gsd plan-phase 2.
