Domain skill for location and geography extraction.
Entity Types

Domain Constraints
location_type: building, house, barn, temple, castle, dungeon, cave, forest, mountain, city, village, shop, tavern, ruins, landmark, othername: max 255 characters
Extraction Rules
- Named places: Cities, ruins, forests, mountains — extract with exact name
- Described areas: "the dark cave", "the forest to the east" — create descriptive name
- Classify type: Hub (safe), dungeon (dangerous), open world (explorable), exotic (dimensions)
- Map connections: How locations connect — paths, portals, boundaries, adjacency
- Note atmosphere: Dangerous, peaceful, mysterious, abandoned
Output Format
Write to entities/world.json:
{
"locations": [
{
"id": 1,
"world_id": 1,
"name": "Eldoria Village",
"description": "Peaceful village in the Eldorian Valley",
"location_type": "village",
"parent_location_id": null,
"created_at": "2026-02-14T10:00:00+00:00",
"updated_at": "2026-02-14T10:00:00+00:00",
"version": 1
}
],
"next_id": 2
}
Key Considerations
- Nested locations: A town inside a forest inside a kingdom — track hierarchy
- Connections: How locations connect (paths, portals, boundaries)
- Scale: Relative sizes help establish world geography
- Cross-references: If needed, track relationships separately in drafts, but final JSON must match
LoreData.from_dict.
