# Agent Memory

A memory management system for AI agents to store and retrieve user interactions and preferences.

[![PyPI version](https://badge.fury.io/py/agent-memory.svg)](https://badge.fury.io/py/agent-memory)
[![Python Support](https://img.shields.io/pypi/pyversions/agent-memory.svg)](https://pypi.org/project/agent-memory/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

## Features

- 🧠 **Persistent Memory Storage**: Store conversations, user preferences, facts, and context
- 🔍 **Powerful Search**: Find memories by content, tags, importance, date ranges, and more  
- 🏷️ **Flexible Tagging**: Organize memories with custom tags
- ⏰ **Expiration Support**: Set automatic expiration for temporary memories
- 📊 **Importance Scoring**: Rank memories by importance (0.0 to 1.0)
- 📈 **Access Tracking**: Monitor memory usage with access counts and timestamps
- 🗃️ **Multiple Backends**: SQLite (default), PostgreSQL, and other SQLAlchemy-supported databases
- 🔧 **Type Safety**: Full type hints and Pydantic models
- 🧪 **Well Tested**: Comprehensive test suite

## Installation

```bash
pip install agent-memory
```

For development:
```bash
pip install agent-memory[dev]
```

## Quick Start

```python
from agent_memory import AgentMemory, MemoryType

# Initialize the memory system
memory = AgentMemory()

# Add a conversation memory
conversation = memory.add_conversation_memory(
    user_id="user123",
    user_message="I love Python programming",
    agent_response="That's great! Python is a versatile language.",
    importance=0.8,
    tags=["programming", "python"]
)

# Add a user preference
preference = memory.add_user_preference(
    user_id="user123",
    preference="programming_language",
    value="Python"
)

# Search for memories
memories = memory.search_memories(
    user_id="user123",
    content_search="Python",
    min_importance=0.5
)

# Get all user preferences
preferences = memory.get_user_preferences("user123")
print(preferences)  # {"programming_language": "Python"}
```

## Core Concepts

### Memory Types

Agent Memory supports different types of memories:

- **`CONVERSATION`**: Dialog between user and agent
- **`USER_PREFERENCE`**: User settings and preferences  
- **`FACT`**: Factual information about the user
- **`CONTEXT`**: Contextual information for conversations
- **`GOAL`**: User goals and objectives
- **`FEEDBACK`**: User feedback on agent responses

### Memory Properties

Each memory contains:

- **`id`**: Unique identifier (UUID)
- **`user_id`**: User identifier
- **`agent_id`**: Optional agent identifier  
- **`content`**: The actual memory content
- **`memory_type`**: Type of memory (see above)
- **`importance`**: Importance score (0.0 to 1.0)
- **`tags`**: List of tags for organization
- **`metadata`**: Additional structured data
- **`timestamp`**: When memory was created
- **`expires_at`**: Optional expiration date

## Advanced Usage

### Custom Database

```python
# Use PostgreSQL
memory = AgentMemory(
    database_url="postgresql://user:pass@localhost/memories"
)

# Use custom SQLite location
memory = AgentMemory(
    database_url="sqlite:///path/to/custom/memories.db"
)
```

### Advanced Searching

```python
from datetime import datetime, timedelta

# Complex search query
memories = memory.search_memories(
    user_id="user123",
    memory_type=MemoryType.CONVERSATION,
    tags=["important", "work"],
    min_importance=0.7,
    created_after=datetime.now() - timedelta(days=7),
    limit=20,
    offset=0
)
```

### Memory Management

```python
# Update memory
updated = memory.update_memory(
    memory_id=conversation.id,
    importance=0.9,
    tags=["programming", "python", "favorite"]
)

# Delete memory
memory.delete_memory(conversation.id)

# Cleanup expired memories
removed_count = memory.cleanup_expired()
```

### Statistics and Analytics

```python
# Get memory statistics
stats = memory.get_memory_stats(user_id="user123")
print(f"Total memories: {stats['total_memories']}")
print(f"By importance: {stats['by_importance']}")
print(f"By type: {stats['by_type']}")
```

## API Reference

### AgentMemory

Main class for memory management.

#### `__init__(database_url=None, auto_cleanup=True)`

Initialize the memory system.

- `database_url`: Database connection string (defaults to local SQLite)
- `auto_cleanup`: Whether to automatically clean expired memories

#### `add_memory(user_id, content, memory_type=CONVERSATION, **kwargs)`

Add a new memory.

**Parameters:**
- `user_id` (str): User identifier
- `content` (str): Memory content
- `memory_type` (MemoryType): Type of memory
- `agent_id` (str, optional): Agent identifier
- `importance` (float): Importance score (0.0-1.0)
- `tags` (List[str]): Tags for organization
- `metadata` (dict): Additional metadata
- `expires_in_days` (int): Days until expiration

#### `search_memories(**filters)`

Search for memories with flexible filtering.

**Filters:**
- `user_id`, `agent_id`, `memory_type`
- `content_search`: Search in content
- `tags`: Filter by tags
- `min_importance`, `max_importance`: Importance range
- `created_after`, `created_before`: Date range
- `limit`, `offset`: Pagination
- `include_expired`: Include expired memories

#### Convenience Methods

- `add_conversation_memory()`: Add user-agent conversation
- `add_user_preference()`: Add user preference
- `get_user_preferences()`: Get all preferences as dict
- `get_user_memories()`: Get all memories for user
- `cleanup_expired()`: Remove expired memories
- `get_memory_stats()`: Get memory statistics
