## 🔧 Technical Implementation Details
|
|
|
|
### Profile-Based LLM Prompts
|
|
|
|
The system now generates context-aware prompts by combining:
|
|
1. Character name and basic identity
|
|
2. Race traits (from RACE_PROMPTS)
|
|
3. Class abilities (from CLASS_PROMPTS)
|
|
4. Personality traits (from PERSONALITY_PROMPTS)
|
|
5. Custom background (if provided)
|
|
6. Legacy personality field (backward compatible)
|
|
|
|
**Example Generated Prompt:**
|
|
```
|
|
You are Thorin, a male Dwarf Warrior. A grizzled veteran seeking redemption.
|
|
You are a dwarf, stout and honorable with deep knowledge of stone and metal.
|
|
You are loyal, practical, and value tradition. You excel in physical combat
|
|
and tactics, preferring direct action and protecting your allies. You are
|
|
brave and decisive in battle. You are serious and focused, prioritizing
|
|
efficiency and practical solutions. You are disciplined and value getting
|
|
things done. Background: Former guardian of the Mountain Keep, exiled after
|
|
a tragic failure.
|
|
```
|
|
|
|
### Import/Export Format
|
|
|
|
**Export Structure:**
|
|
```json
|
|
{
|
|
"version": "1.0",
|
|
"character": {
|
|
"id": "...",
|
|
"name": "Character Name",
|
|
"description": "...",
|
|
"profile": {
|
|
"gender": "Male",
|
|
"race": "Elf",
|
|
"character_class": "Wizard",
|
|
"personality_type": "Measured",
|
|
"background": "...",
|
|
"avatar_data": null
|
|
},
|
|
"llm_model": "gpt-4o",
|
|
"conversation_history": [],
|
|
"pending_response": false
|
|
},
|
|
"created_at": "2025-10-12T00:00:00",
|
|
"export_type": "storyteller_rpg_character"
|
|
}
|
|
```
|
|
|
|
**Import Process:**
|
|
1. Validates JSON structure
|
|
2. Extracts character data
|
|
3. Generates new ID to avoid conflicts
|
|
4. Clears conversation history
|
|
5. Adds to session
|
|
6. Notifies storyteller via WebSocket
|
|
|
|
### Backward Compatibility
|
|
|
|
The system maintains full backward compatibility:
|
|
- Legacy characters without profiles still work
|
|
- `build_character_system_prompt()` handles both types
|
|
- Legacy endpoint available at `/characters/legacy/`
|
|
- Simple creation mode in SessionSetup
|
|
