msw-packages — Claude Code skill for the MSW package catalog

Checks the MSW package catalog before an agent builds a standard game feature from scratch. When a match turns up, the agent can review it and ask whether to integrate it.

What msw-packages does

Before implementing a common game feature, the skill checks it against the MSWPackages catalog. Entries cover systems such as inventory, shops, quests, dialogue, player saves, and loot tables. When a request could fit more than one package, such as basic or advanced rankings, the agent can compare the options.

This skill is an index, not a mirrored package library: the agent retrieves a matching package’s README for details and integration steps. If the request could mean a complete system or only its screen, the agent asks which one is wanted before fetching package files. It then presents integration and scratch development as choices. Packages are not installed automatically, since their UUIDs, sprite RUIDs, or naming conventions may conflict with a project.

What it helps with

  • find a ready-made package for a game system
  • compare packages for a ranking feature
  • clarify whether an inventory request includes item logic
  • review integration before installing a package

Example prompts for the agent

  • Check the MSWPackages catalog before building an inventory system.
  • Compare the ranking packages and recommend one to review.
  • Find a quest package and ask whether I need its logic or just the screen.
