Use this skill for vector and matrix maths in melonJS — Vector2d, Vector3d, their observable variants, Matrix2d, Matrix3d, and the math utility functions. Covers which methods mutate and which allocate, the vector pool and when clone() is the wrong tool, interpolation with lerp, slerp, damp and moveTowards, and the argument defaults that silently drop a component. Triggers on: Vector2d, Vector3d, ObservableVector2d, ObservableVector3d, Matrix2d, Matrix3d, vector, vector maths, dot, cross, norma…

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-math' ] || [ -L ~/.agents/skills/'melonjs-math' ]; then echo 'A skill folder named melonjs-math 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 "$d" checkout --quiet 'ea6157308367fab7a5aa7ba6ee719b4a1f79fae8' -- 'packages/melonjs/skills/melonjs-math' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/melonjs/skills/melonjs-math' ~/.agents/skills/'melonjs-math' && 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-math' ~/.claude/skills/'melonjs-math' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
