Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# melonJS — agent instructions

> **This is a template for a game that *uses* melonJS, not instructions for
> working on the engine itself.** Copy it to your own project root:
>
> ```bash
> cp node_modules/melonjs/skills/AGENTS.md ./AGENTS.md
> ```
>
> Already have an `AGENTS.md`? Paste the sections below into it. Codex, Cursor,
> Gemini CLI and anything else following the `AGENTS.md` convention will read it
> from your project root. Claude Code users should install the plugin instead —
> `/plugin marketplace add melonjs/melonJS` — which registers the same guidance
> as 25 routed skills.

This project uses **melonJS 20.x**, an open-source HTML5 game engine covering
2D, 2.5D and 3D, running on WebGPU, WebGL 2 or Canvas with automatic fallback.

## Read these before writing engine code

Task-oriented guides ship with the package at `node_modules/melonjs/skills/`,
one directory per subsystem, each ending with a symptom → cause table.

**Start at `node_modules/melonjs/skills/melonjs/SKILL.md`** — it routes to the
right one for the task. Do not read all of them; read the router, then the one
or two it points at.

For anything the guides do not cover, fetch

How to install

The exact contents, by fingerprint
mdr add melonjs/melonjs/packages/melonjs/skills/AGENTS.md@sha256:0fd90d34f08e0b2f

The line at the top of this page pins the label git:20261030.33bfc96, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
