SKILL.md

<objective> Guide the user through MVP-mode planning for a phase. The command:

  1. Prompts for an "As a / I want to / So that" user story (three structured questions)
  2. Runs SPIDR splitting check — if the story is too large, walks through Spike/Paths/Interfaces/Data/Rules and offers to split into multiple phases
  3. Writes Mode: mvp and the reformatted Goal: to the phase's ROADMAP.md section
  4. Delegates to /gsd plan-phase <N> which auto-detects MVP mode via the roadmap field

Phase 1 of the vertical-mvp-slice PRD shipped the planner-side machinery; this command is the user entry point for it. </objective>

<executioncontext> @~/.claude/gsd-core/workflows/mvp-phase.md @~/.claude/gsd-core/references/spidr-splitting.md @~/.claude/gsd-core/references/user-story-template.md </executioncontext>

<runtimenote> Copilot (VS Code): Use vscodeaskquestions wherever this workflow calls AskUserQuestion. Equivalent API. </runtime_note>

<context> Phase number: $ARGUMENTS (required — integer or decimal like 2.1)

The phase must already exist in ROADMAP.md (created via /gsd new-project, /gsd add-phase, or /gsd insert-phase). This command does not create new phases — it converts an existing phase to MVP mode. </context>

<process> Execute the mvp-phase workflow from @~/.claude/gsd-core/workflows/mvp-phase.md end-to-end. Preserve all gates: phase existence, status guard (refuse in_progress/completed), user-story format validation, SPIDR splitting check, ROADMAP write confirmation, plan-phase delegation. </process>
