MSU Skills

Use MapleStory Universe resources with AI agents.

nexpace-limited.github.io/msu-skills — the same install steps and skill list as a web page.

This repository provides installable MSU Resource Skills for AI agents. The skills help agents discover and use MSU game resources through Resource MCP while building Synergy Apps.

Within the NEXPACE skills ecosystem, this repository is the msu-skills catalog — the home of MSU (≒ NEXPACE) common skills and shared modules. Product-specific skill sets live in their own repositories and depend on these.

Its plugins install independently:

Installation

Choose the channel that matches your agent. All of them install the same SKILL.md sources; they differ in plugin selection and MCP setup.

Claude Code — plugin

This repository is its own plugin marketplace, so it is added and installed directly.

/plugin marketplace add NEXPACE-Limited/msu-skills
/plugin install msu@msu-skills             # Maple assets + maple-lookup MCP
/plugin install game-tools@msu-skills      # game quality gates, no credential
/plugin install msu-statusline@msu-skills  # MSU notices in the status line, no credential

Install any of them. Later releases arrive with /plugin marketplace update msu-skills.

msu-statusline is the one plugin that also needs a step of its own: Claude Code keeps statusLine in your own settings rather than in plugin config, so run /msu-statusline:msu-statusline-install once and it is written there for you. A status line you already use is kept and rendered above the MSU line, not replaced.

Installing the msu plugin registers the skills and the maple-lookup MCP server together — the server definition is bundled as plugins/msu/.mcp.json at that plugin’s root, so Claude Code picks it up automatically. When the plugin is enabled, Claude Code prompts for your MSU Builder OpenAPI key and stores it securely — no manual MCP setup is needed.

Other agents — skills CLI

Requires Node.js 22.20+.

npx skills add NEXPACE-Limited/msu-skills

This installs the skills for your active coding agent, such as Cursor, Codex CLI, OpenCode, Windsurf, Continue, Cline, or Zed. (Claude Code users should prefer the plugin channel above.) The skills do not bundle a CLI helper or require shell utilities.

This offers the skills of every plugin in the repository at once. Name the ones you want to narrow it:
