jnuyens/gsd:mvp-phase

<objective> Guide the user through MVP-mode planning for a phase. Prompts for an "As a / I want to / So that" user story, runs SPIDR splitting check on the story, writes the result to ROADMAP.md, and delegates to `/gsd:plan-phase` (which auto-detects MVP via the roadmap mode field).

Orchestrator role: Parse phase argument, validate phase, gather user story, run SPIDR check, persist mode + story to ROADMAP.md, then route to plan-phase. </objective>

<execution_context> @${CLAUDE_PLUGIN_ROOT}/workflows/mvp-phase.md @${CLAUDE_PLUGIN_ROOT}/references/user-story-template.md @${CLAUDE_PLUGIN_ROOT}/references/spidr-splitting.md @${CLAUDE_PLUGIN_ROOT}/references/planner-mvp-mode.md </execution_context>

<runtime_note> Copilot (VS Code): Use vscode_askquestions wherever this workflow calls AskUserQuestion. They are equivalent — vscode_askquestions is the VS Code Copilot implementation of the same interactive question API.

TEXT_MODE fallback: Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. </runtime_note>

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

Flags:

• --force — Allow operating on in_progress / completed phases
• --text — Use plain-text numbered lists instead of TUI menus </context>

<process> Execute the mvp-phase workflow from @${CLAUDE_PLUGIN_ROOT}/workflows/mvp-phase.md end-to-end. Preserve all workflow gates (phase validation, user-story prompt, SPIDR check, ROADMAP.md persistence, delegation to plan-phase). </process>

<output_format> When MVP planning concludes (user story written, ROADMAP.md updated, plan-phase delegated), emit a Next Up continuation block following the pattern in references/continuation-format.md:

• Show MVP-planning status (e.g., ## ✓ Phase N MVP-Planned — vertical slice captured)
• Emit a ## ▶ Next Up heading with /gsd:execute-phase N (TDD execution)
• Use `/clear` then: before the command
• Include a parenthetical: (/clear is safe — /gsd:resume-work restores position from HANDOFF.json if you change your mind)

MVP planning is a deliberate slice-of-the-cake exercise; clearing context before execution keeps TDD focused on the captured story rather than the planning conversation. </output_format>
