mvp-skeleton

name	mvp-skeleton
description	Use when creating, scaffolding, planning, or implementing an MVP, prototype, runnable vertical slice, product skeleton, v0, or thin vertical slice and the agent must prevent overbuilding. Trigger for MVP作成, プロトタイプ, 骨格だけ, core runnable path, thin vertical slice, scope creep, over-polish, and cases where early implementation is getting unnecessary UI, architecture, features, or tests.

MVP Skeleton

Tool Commands

Use the command packet before applying this skill's workflow:

python3 tools/agent_tools/skill_tool_commands.py show --skill mvp-skeleton --format text

Execute the required and task-matching conditional commands that the packet prints.

1. Read agents/skills/mvp-skeleton.md.
2. Before editing, write a compact MVP contract in working notes, a run bundle, or the user-facing plan:
   • core_user: who uses the skeletal slice
   • core_loop: one input-to-useful-output path
   • success_signal: observable result that proves the core loop
   • runtime_floor: local run or inspection path that exercises the loop
   • stop_line: tempting work that must be deferred
3. Classify every candidate feature as required, stub, or defer; choose defer when uncertain.
4. Keep only the required items that are necessary for one end-to-end path.
5. Prefer one vertical slice over reusable infrastructure, extra workflows, broad abstractions, and generalized services.
6. Stub auth, external services, payments, imports, analytics, admin tools, notifications, search, exports, persistence, and deployment unless the core loop specifically depends on them.
7. For frontend work, make the entry screen the usable product surface rather than a landing page unless the user explicitly asked for a landing page.
8. Add a smoke check that proves the MVP path runs.
9. Stop when the core runnable path is available and report:
   • core loop implemented
   • run or inspection path
   • smoke check performed
   • deferred list capped at five items
10. Treat the deferred list as success evidence and scope control.
