The brief
A description with a clear identity
A copper-and-iron survey automaton with layered shoulder armor, a glowing furnace core, two back chimneys and a mining hammer. Give it 120 health and 8 melee damage. It walks, retaliates when attacked, and swings its hammer with warm sparks.
This brief combines a visual direction with explicit health and damage values. The generated specification contains 54 cuboids and a neutral melee behavior configuration.
- Layered copper-and-iron shoulder armor and a recessed visor.
- A furnace-colored chest core, twin back chimneys and piston-like legs.
- A squared mining hammer and a Forge Hammer Strike browser preview.
