Msw Painter

When msw-search comes up empty, this generates pixel art sprites on the fly and uploads them to get a sprite RUID. You pick between chunky pixel style (retro icons, tiles, 16×16 logical grid with hard outlines) or maple cartoon style (MapleStory-inspired characters with selout shading and selective antialiasing on larger canvases). The workflow is strict: write SVG, Canvas, or HTML following per-style rules, render to PNG via a sandboxed Puppeteer script, then call the two-step asset upload. It won't do animation or audio, just static sprites. The style guides are detailed enough that you won't accidentally mix gradients into your NES-looking slime, and the render script blocks network requests so nothing leaks during headless Chrome execution.

MSW Painter

A workflow for registering a hand-drawn pixel art sprite as a sprite resource. Call msw-search first, and only invoke this skill when no suitable RUID is found.

This skill is dedicated to the sprite category. It does not handle animation / audio / avatar / atlas.

The painter supports two pixel art styles: chunky pixel (retro, icon/tile feel) and maple cartoon (MapleStory-inspired, character/NPC feel). Pick one before writing code — see step 2 below.

When to invoke

Situation	Action
User wants a specific sprite	First use `msw-search` (Resource search section, sprite category)
`msw-search` returns an RUID that matches the intent	Use that RUID directly. Do not invoke painter.
No search results, or all results are unsuitable	Invoke painter → create directly
User explicitly says "I need a hand-drawn looking character/icon"	Invoke painter directly
