Msw Ui System

If you're building UI in MSW, this is your single entry point for everything: design fundamentals (anchor/pivot/RectTransform), full component API tables (ButtonComponent, TextGUIRendererComponent, ScrollLayoutGroup, GridView, all the enums), builder invocation through msw_ui_builder.cjs, and runtime mlua patterns for popups, toasts, HP bars, drag, and cooldown timers. The skill enforces strict routing to sub-references based on keywords and blocks direct JSON editing entirely, forcing all mutations through the builder to prevent UUID and binding breakage. It includes layout recipes for common patterns (HUD, inventory grid, scroll list) and handles the .ui to .mlua UUID auto-binding that trips everyone up. The workflow is opinionated: match a recipe first, invoke builder, inject bindings, let auto-lint catch mistakes. Sound integration is mandatory for interactive buttons unless you opt out.

msw-ui-system

MSW .ui single entry point — design guide + component API + builder invocation + runtime patterns bundled into one skill.

Role division with existing skills:

Skill	Responsibility
`msw-ui-system` (this skill)	Everything `.ui` — design (which/when/why), component API/enum (what), builder invocation (how to mutate), runtime mlua patterns. `.ui` mutations must always go through this skill's builder
`references/templates/`	Pre-built style bundles — `.ui` + ruid-map + button handler packages
