<arguments>$ARGUMENTS</arguments>
The text inside <arguments> is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.
<objective> Guide the user through MVP-mode planning for a phase. The command:
- Prompts for an "As a / I want to / So that" user story (three structured questions)
- Runs SPIDR splitting check — if the story is too large, walks through Spike/Paths/Interfaces/Data/Rules and offers to split into multiple phases
- Writes
**Mode:** mvpand the reformatted**Goal:**to the phase's ROADMAP.md section - 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>

<runtimenote> **Copilot (VS Code):** Use `vscodeaskquestions wherever this workflow calls AskUserQuestion`. Equivalent API. </runtime_note>
<context> Phase number: the <arguments> block (required — integer or decimal like 2.1)
The phase must already exist in ROADMAP.md (created via /gsd-new-project, /gsd-phase, or /gsd-phase --insert). 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>
