json-formatter

Base skill for JSON output formatting. All extraction skills produce JSON that can be loaded by the Lore GUI (LoreData.from_dict).

Rules

  1. Valid JSON: Output must be parseable JSON — no trailing commas, no comments.
  2. Export schema: Use the GUI export format defined in src/presentation/gui/lore_data.py.
  3. Plural collections: Each entity collection is a top-level key with a plural name and an array value (e.g., worlds, characters, locations).
  4. IDs are consistent: Use integer IDs for GUI export collections. For entity types that use UUIDs in the domain model, use UUID strings consistently across references.
  5. Field names: Use exact domain field names (snake_case). Do not invent type or entity_type unless that field exists in the domain model.
  6. Dates: Use ISO 8601 strings for timestamps (created_at, updated_at, start_date, end_date).

Output Structure (Export-Compatible)

json
1{ 2 "worlds": [], 3 "characters": [], 4 "locations": [], 5 "quests": [], 6 "items": [], 7 "events": [], 8 "stories": [], 9 "storylines": [], 10 "tags": [], 11 "images": [], 12 "choices": [], 13 "flowcharts": [], 14 "handouts": [], 15 "inspirations": [], 16 "environments": [], 17 "banners": [], 18 "character_relationships": [], 19 "factions": [], 20 "shops": [], 21 "maps": [], 22 "notes": [], 23 "requirements": [], 24 "sessions": [], 25 "tokenboards": [], 26 "pity": [], 27 "pulls": [], 28 "player_profiles": [], 29 "currencies": [], 30 "rewards": [], 31 "purchases": [], 32 "event_chains": [], 33 "faction_memberships": [], 34 "lore_axioms": [], 35 "music_controls": [], 36 "music_states": [], 37 "music_themes": [], 38 "music_tracks": [], 39 "progression_events": [], 40 "character_states": [], 41 "textures": [], 42 "models": [], 43 "next_id": 1 44}

Required Fields (Core Entities)

Use these minimum fields so JSON loads without validation errors:

  • worlds: id, name, description, created_at, updated_at, version
  • characters: id, world_id, name, backstory, status, abilities, created_at, updated_at, version
  • locations: id, world_id, name, description, location_type, created_at, updated_at, version
  • quests: id, world_id, name, description, objectives, status, participant_ids, reward_ids, created_at, updated_at, version

If a field is unknown, set it to null or an empty list (for arrays), but keep the key.
