What msw-planning does

The skill asks focused questions, then uses a MapleStory Worlds catalog of genres, map types, mechanics, and effort hints to shape a game concept. It produces a GDD and milestone roadmap in Markdown. For ambitious ideas, it scopes the initial build around a playable core and leaves broader features for later phases.

Already have planning files? The skill checks Docs/ and Archive/ to work out where the project stands before guiding a resume. It tracks plans and progress; it does not implement game code. Its planning is specific to MapleStory Worlds and mLua, so that environment shapes the designs it can help plan.

What it helps with

  • turn a game idea into a MapleStory Worlds plan
  • scope the first build around a playable core
  • map development into milestones and phases
  • work out the next step in an existing project

Example prompts for the agent

  • Help me plan a MapleStory Worlds game and draft its GDD.
  • Cut this concept down to an MVP and plan the first phase.
  • Pick up this game project and figure out the next planning step.
