# Long-Term Memory System
|
|
|
|
Stores persistent facts about the user, their preferences, routines, and important information.
|
|
|
|
## Features
|
|
|
|
- **Persistent Storage**: SQLite database for long-term storage
|
|
- **Categories**: Personal, family, preferences, routines, facts
|
|
- **Confidence Scoring**: Track certainty of each fact
|
|
- **Source Tracking**: Know where facts came from (explicit, inferred, confirmed)
|
|
- **Fast Retrieval**: Indexed lookups and search
|
|
- **Prompt Integration**: Format memory for LLM prompts
|
|
|
|
## Usage
|
|
|
|
```python
|
|
from memory.manager import get_memory_manager
|
|
from memory.schema import MemoryCategory, MemorySource
|
|
|
|
manager = get_memory_manager()
|
|
|
|
# Store explicit fact
|
|
manager.store_fact(
|
|
category=MemoryCategory.PREFERENCES,
|
|
key="favorite_color",
|
|
value="blue",
|
|
confidence=1.0,
|
|
source=MemorySource.EXPLICIT
|
|
)
|
|
|
|
# Store inferred fact
|
|
manager.store_fact(
|
|
category=MemoryCategory.ROUTINES,
|
|
key="morning_routine",
|
|
value="coffee at 7am",
|
|
confidence=0.8,
|
|
source=MemorySource.INFERRED,
|
|
context="Mentioned in conversation on 2024-01-06"
|
|
)
|
|
|
|
# Get fact
|
|
fact = manager.get_fact(MemoryCategory.PREFERENCES, "favorite_color")
|
|
if fact:
|
|
print(f"Favorite color: {fact.value}")
|
|
|
|
# Search facts
|
|
facts = manager.search_facts("coffee", category=MemoryCategory.ROUTINES)
|
|
|
|
# Format for LLM prompt
|
|
memory_text = manager.format_for_prompt()
|
|
# Use in system prompt: "## User Memory\n{memory_text}"
|
|
```
|
|
|
|
## Categories
|
|
|
|
- **PERSONAL**: Personal facts (name, age, location)
|
|
- **FAMILY**: Family member information
|
|
- **PREFERENCES**: User preferences (favorite foods, colors)
|
|
- **ROUTINES**: Daily/weekly routines
|
|
- **FACTS**: General facts about the user
|
|
|
|
## Memory Write Policy
|
|
|
|
### Explicit Facts (confidence: 1.0)
|
|
- User explicitly states: "My favorite color is blue"
|
|
- Source: `MemorySource.EXPLICIT`
|
|
|
|
### Inferred Facts (confidence: 0.7-0.9)
|
|
- Inferred from conversation: "I always have coffee at 7am"
|
|
- Source: `MemorySource.INFERRED`
|
|
|
|
### Confirmed Facts (confidence: 0.9-1.0)
|
|
- User confirms inferred fact
|
|
- Source: `MemorySource.CONFIRMED`
|
|
|
|
## Integration with LLM
|
|
|
|
Memory is formatted and injected into system prompts:
|
|
|
|
```python
|
|
memory_text = manager.format_for_prompt(limit=20)
|
|
system_prompt = f"""
|
|
You are a helpful assistant.
|
|
|
|
## User Memory
|
|
|
|
{memory_text}
|
|
|
|
Use this information to provide personalized responses.
|
|
"""
|
|
```
|
|
|
|
## Storage
|
|
|
|
- **Database**: `data/memory.db` (SQLite)
|
|
- **Schema**: See `memory/schema.py`
|
|
- **Indexes**: Category, key, last_accessed for fast queries
|
|
|
|
## Future Enhancements
|
|
|
|
- Semantic search using embeddings
|
|
- Memory summarization
|
|
- Confidence decay over time
|
|
- Conflict resolution for conflicting facts
|
|
- Memory validation and cleanup
