Use this skill when writing melonJS code that may be based on pre-20.x knowledge, when migrating a game from melonJS 19.x or earlier, or when an API you expected does not exist. Covers the mandatory async Application.init(), the WebGL 2 baseline and WebGPU backend, renderable post effects replacing the shader property, the deprecated exports still present, and what changed again during 20.x. Triggers on: migration, upgrade, melonJS 19, me.game, me.video.init, video.renderer, renderable.shader, …

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'melonjs-20-migration' ] || [ -L ~/.agents/skills/'melonjs-20-migration' ]; then echo 'A skill folder named melonjs-20-migration already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melonjs/melonJS' "$d" && git -C "$d" checkout --quiet 'ea6157308367fab7a5aa7ba6ee719b4a1f79fae8' -- 'packages/melonjs/skills/melonjs-20-migration' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/melonjs/skills/melonjs-20-migration' ~/.agents/skills/'melonjs-20-migration' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'melonjs-20-migration' ~/.claude/skills/'melonjs-20-migration' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
