# Calute Improvements - Integration Guide

This document describes all the improvements made to the Calute project and how to use them alongside the existing codebase.

## Overview

Successfully integrated `MemoryStore` as the primary memory system in Calute, replacing the basic `MemoryStore` while maintaining backward compatibility.

## Changes Made

### 1. **Core Integration (calute/calute.py)**

- Updated import to use `MemoryStore` instead of `MemoryStore`
- Added `memory_config` parameter to Calute's `__init__` method
- Enhanced initialization with configurable parameters:
  - `max_short_term`: Maximum short-term memories (default: 100)
  - `max_working`: Maximum working memories (default: 10)
  - `max_long_term`: Maximum long-term memories (default: 10000)
  - `enable_vector_search`: Enable vector-based similarity search
  - `embedding_dimension`: Dimension for embeddings (default: 768)
  - `enable_persistence`: Enable saving memories to disk
  - `persistence_path`: Path for persistent storage
  - `cache_size`: Size of memory cache (default: 100)

### 2. **Memory Module Updates (calute/memory.py)**

- Renamed original `MemoryStore` to `BasicMemoryStore` with deprecation notice
- Added missing methods to `MemoryStore`:
  - `consolidate_memories()`: Consolidates memories into summaries
  - `search_memories()`: Text-based memory search
  - `analyze_memory_patterns()`: Analyzes memory usage patterns

### 3. **Export Updates (calute/**init**.py)**

- Updated exports to include both `MemoryStore` and `MemoryEntry`
- Maintained `MemoryStore` export as alias for backward compatibility
- Added deprecation comment for clarity

## Features of MemoryStore

### Memory Types

- **SHORT_TERM**: Recent, temporary memories
- **LONG_TERM**: Important, persistent memories
- **EPISODIC**: Event-based memories
- **SEMANTIC**: Fact-based memories
- **WORKING**: Current task-related memories
- **PROCEDURAL**: How-to knowledge

### Advanced Features

1. **Indexing System**
   - By ID, agent, type, tags, timestamp, and importance
   - Fast retrieval and search capabilities

2. **Caching**
   - LRU cache for frequently accessed memories
   - Cache hit/miss tracking for performance monitoring

3. **Memory Consolidation**
   - Automatic grouping by memory type
   - Priority-based summarization

4. **Pattern Analysis**
   - Memory type distribution
   - Common tags identification
   - Access pattern tracking

5. **Persistence**
   - Optional save/load to disk
   - Pickle-based serialization

## Usage Example

```python
from calute import Calute, Agent

# Initialize with enhanced memory
calute = Calute(
    client=oai_client,
    enable_memory=True,
    memory_config={
        "max_short_term": 50,
        "max_long_term": 5000,
        "enable_persistence": True,
        "persistence_path": "./agent_memories",
        "cache_size": 200
    }
)

# Memory operations
calute.memory_store.add_memory(
    content="Important user preference",
    memory_type=MemoryType.LONG_TERM,
    agent_id="assistant",
    importance_score=0.9,
    tags=["preference", "user"]
)

# Search memories
results = calute.memory_store.search_memories(
    query="preference",
    agent_id="assistant"
)

# Get consolidated summary
summary = calute.memory_store.consolidate_memories("assistant")
```

## Backward Compatibility

The integration maintains full backward compatibility:

- `MemoryStore` is aliased to `MemoryStore`
- All existing code using `MemoryStore` continues to work
- Basic operations remain unchanged

## Testing

All tests pass successfully:

- ✅ Basic memory integration
- ✅ Advanced memory features
- ✅ Memory with conversation context
- ✅ Backward compatibility

## Benefits

1. **Improved Performance**: Indexing and caching reduce memory retrieval time
2. **Better Organization**: Six memory types for different use cases
3. **Enhanced Search**: Text-based and tag-based search capabilities
4. **Persistence**: Optional saving of memories across sessions
5. **Analytics**: Memory pattern analysis for insights
6. **Scalability**: Handles up to 10,000 long-term memories efficiently

## Migration Guide

For existing code:

1. No changes required - `MemoryStore` still works
2. To use new features, access via `MemoryStore` directly
3. Configure advanced features through `memory_config` parameter

## Future Enhancements

Potential improvements:

1. Vector embeddings for semantic search (when `enable_vector_search=True`)
2. Memory decay and forgetting mechanisms

## 🔄 Integration with Existing Code

The improvements are designed to work **alongside** the existing codebase without breaking changes:

### Using Enhanced Features (Optional)

```python
# 1. Import the enhanced modules
from calute.config import CaluteConfig, set_config
from calute.memory_enhanced import MemoryStore
from calute.executors_enhanced import EnhancedFunctionExecutor
from calute.logging_config import get_logger

# 2. Configure (optional - defaults work fine)
config = CaluteConfig(
    executor={"default_timeout": 45.0},
    memory={"max_short_term": 100},
)
set_config(config)

# 3. Use enhanced memory (drop-in replacement)
memory = MemoryStore(
    max_short_term=100,
    enable_persistence=True,
)

# 4. Your existing code continues to work
agent = Agent(
    model="gpt-4",
    functions=[...],  # Your existing functions
)
```

### Gradual Adoption

You can adopt improvements gradually:

1. **Start with configuration**: Just add a `calute.yaml` config file
2. **Add logging**: Use `get_logger()` for better debugging
3. **Enhance memory**: Replace `MemoryStore` with `MemoryStore`
4. **Add monitoring**: Enable metrics and tracing when needed

All existing code continues to work:

```python
# Original code still works
from calute import Agent, Calute
client = openai.OpenAI(...)
calute = Calute(client)

# Enhanced features are opt-in
calute.memory = MemoryStore()  # Optional upgrade
```

## 🚀 Quick Start Examples

### Example 1: Basic Usage with Config

```python
from calute import Agent, Calute
from calute.config import CaluteConfig

# Load config from file or environment
config = CaluteConfig.from_file("config.yaml")

# Everything else works as before
agent = Agent(model="gpt-4", functions=[...])
```

### Example 2: Enhanced Memory

```python
from calute.memory_enhanced import MemoryStore, MemoryType

# Create enhanced memory with persistence
memory = MemoryStore(
    enable_persistence=True,
    persistence_path="./memory_store"
)

# Add tagged memories
memory.add_memory(
    content="Important fact",
    memory_type=MemoryType.LONG_TERM,
    agent_id="agent1",
    tags=["important", "fact"],
    importance_score=0.9
)

# Search by tags
results = memory.retrieve_memories(tags=["important"])
```

### Example 3: Extended LLM Providers

```python
from calute.llm_providers import create_llm_client

# Use any provider
client = create_llm_client("anthropic", api_key="...")
# or
client = create_llm_client("ollama", base_url="http://localhost:11434")

# Use with Calute as normal
calute = Calute(client)
```

### Example 4: Monitoring & Logging

```python
from calute.logging_config import get_logger

logger = get_logger("my_module")

# Log with structure
logger.log_function_call(
    agent_id="agent1",
    function_name="search",
    arguments={"query": "test"},
    result="success",
    duration=1.5
)

# Get Prometheus metrics
metrics = logger.get_metrics()
```

## 🧪 Testing the Improvements

Run the test suite to verify everything works:

```bash
# Run all tests
python test_improvements.py

# Or use pytest (if dependencies installed)
pytest tests/

# Run with coverage
pytest tests/ --cov=calute --cov-report=html
```

## 📦 Optional Dependencies

The improvements use optional dependencies. Install what you need:

```bash
# Core improvements (works without these)
pip install pyyaml  # For YAML configs

# Advanced features
pip install scikit-learn  # For vector similarity
pip install structlog     # For structured logging
pip install prometheus-client  # For metrics
pip install httpx tenacity  # For extended LLM providers

# Or install all dev dependencies
pip install -e ".[dev]"
```

## 🔧 Environment Variables

Configure via environment:

```bash
export CALUTE_ENVIRONMENT=production
export CALUTE_EXECUTOR_DEFAULT_TIMEOUT=60
export CALUTE_MEMORY_MAX_SHORT_TERM=200
export CALUTE_LOGGING_LEVEL=DEBUG
```

## 🐳 Docker Support

Run with Docker:

```bash
# Build image
docker build -t calute:latest .

# Run with docker-compose
docker-compose up

# Includes PostgreSQL, Redis, Prometheus, Grafana
```

## 🎯 Benefits

1. **Better Error Handling**: Graceful failures with retries
2. **Performance**: Indexed memory, connection pooling
3. **Observability**: Metrics, tracing, structured logs
4. **Flexibility**: Multiple LLM providers, configurable everything
5. **Developer Experience**: Tests, linting, automation
6. **Production Ready**: Docker, CI/CD, monitoring

## 📝 Migration Guide

To use enhanced features in existing code:

1. **No changes required** - existing code works as-is
2. **Opt-in gradually** - adopt features as needed
3. **Replace selectively** - e.g., just upgrade memory or logging
4. **Configure externally** - use config files without code changes

## 🆘 Troubleshooting

If you encounter issues:

1. **Import errors**: Install optional dependencies as needed
2. **Config not loading**: Check file path and format (JSON/YAML)
3. **Memory persistence**: Ensure write permissions for persistence path
4. **LLM providers**: Check API keys and endpoints
