Artifact Game Builder

Produces one file. That file runs. That is the whole deliverable.

When to trigger

Clear triggers:

• "Build me a platformer / shooter / puzzle / roguelike"
• "Make a playable artifact"
• "Can you prototype this game idea"
• "Game jam entry"

Not this skill:

• Multi-file Vite / Next.js game projects → point to playground/ or freshtechbro/claudedesignskills.
• Full Godot/Unity/Bevy work.
• Asset generation only → use sprite-atlas-builder.
