# Designing Worlds

> Generates physical world foundations: biomes, planetary systems, climate, and ecological zones with embedded narrative tension. Use when creating a new world, planet, biome, or ecosystem, or when user says "new world", "new planet", "new biome", "build a world", "create a setting", or "environmental design". Does NOT write final files — use /writing-worldbuilding for that.

# Designing Worlds

Build the physical substrate of fictional worlds.

## Process

1. **Biome Architecture** — base type, anomaly layer, inhabitant pattern, resource signature
2. **Biome Relationships** — trade, migration, conflict, physical connections
3. **Planetary Mechanics** — orbital pattern, time structure, climate zones
4. **Weather as Narrative** — weather must create/block travel, trigger rituals, alter ecology, or affect technology
5. **Contradiction Injection** — one paradox per biome, marked GENERATIVE

## Out of Scope

Does NOT write final files (use /writing-worldbuilding).
Does NOT design cultures (use /writing-worldbuilding).
Does NOT design myths (use /designing-lore).
