# IMPORTANT: Post-Edit Pipeline Requirement
# After any file modification (Write, Edit, or any code change), you MUST invoke the post-edit pipeline:
#   ./.claude/hooks/cfn-invoke-post-edit.sh "$FILE_PATH" --agent-id "$AGENT_ID"
# This is mandatory for all file edits to ensure code quality and validation.
# The pipeline will run compilation checks and TDD compliance verification.

# IMPORTANT: CodeSearch Semantic Search (Before Making Changes)
# Before implementing any changes, ALWAYS query the codebase for similar patterns:
#   /codebase-search "relevant search terms for your task" --top 5
#   /codebase-search "error pattern or issue you're fixing" --top 3
# Also query past errors and learnings:
#   ./.claude/skills/cfn-codesearch/query-agent-patterns.sh --task-description "Your task description"
#   ./.claude/skills/cfn-codesearch/query-agent-patterns.sh --task-description "Your task description"
# This prevents duplicated work and leverages existing solutions.

> **Skills**:  CodeSearch (semantic search) | Post-edit hook (file validation)

## Technical Expertise

### Mem0 Client Setup

```python
# Basic mem0 setup
from mem0 import Memory

# Initialize with default config (uses in-memory storage)
memory = Memory()

# Initialize with custom config
config = {
    "llm": {
        "provider": "openai",
        "config": {
            "model": "gpt-4o-mini",
            "temperature": 0.1,
        }
    },
    "embedder": {
        "provider": "openai",
        "config": {
            "model": "text-embedding-3-small"
        }
    },
    "vector_store": {
        "provider": "qdrant",
        "config": {
            "collection_name": "memories",
            "host": "localhost",
            "port": 6333,
        }
    },
    "version": "v1.1"
}

memory = Memory.from_config(config)
```

### Memory CRUD Operations

```python
# Add memories
# For a user
result = memory.add(
    "I prefer dark mode interfaces and use VSCode as my editor",
    user_id="user_123"
)

# For an agent
result = memory.add(
    "User prefers concise responses with code examples",
    user_id="user_123",
    agent_id="coding_assistant"
)

# With metadata
result = memory.add(
    "Completed Python certification in 2024",
    user_id="user_123",
    metadata={"category": "education", "year": 2024}
)

# Search memories
# Basic search
results = memory.search(
    "What are the user's coding preferences?",
    user_id="user_123"
)

# Search with filters
results = memory.search(
    "educational background",
    user_id="user_123",
    limit=5
)

# Get all memories
all_memories = memory.get_all(user_id="user_123")

# Get specific memory
mem = memory.get(memory_id="mem_abc123")

# Update memory
memory.update(
    memory_id="mem_abc123",
    data="Updated: I now prefer light mode for daytime work"
)

# Delete memory
memory.delete(memory_id="mem_abc123")

# Delete all user memories
memory.delete_all(user_id="user_123")
```

### Memory History & Versioning

```python
# Get memory history (v1.1+)
history = memory.history(memory_id="mem_abc123")

# History returns all versions with timestamps
for version in history:
    print(f"Version {version['id']}: {version['memory']}")
    print(f"Created: {version['created_at']}")
```

### Mem0 Platform (Cloud API)

```python
from mem0 import MemoryClient

# Initialize platform client
client = MemoryClient(api_key="your-api-key")

# Add memory
client.add(
    "User is a senior developer focusing on backend systems",
    user_id="user_123"
)

# Search memories
results = client.search(
    "What does the user work on?",
    user_id="user_123"
)

# Get all memories for organization
all_mems = client.get_all()
```

### Integration with LLM Workflows

```python
from mem0 import Memory
from openai import OpenAI

memory = Memory()
openai_client = OpenAI()

def chat_with_memory(user_id: str, message: str) -> str:
    # Retrieve relevant memories
    relevant_memories = memory.search(message, user_id=user_id, limit=5)

    # Build context from memories
    memory_context = "\n".join([
        f"- {mem['memory']}"
        for mem in relevant_memories
    ])

    # Create system prompt with memory context
    system_prompt = f"""You are a helpful assistant with memory of past conversations.

Relevant memories about this user:
{memory_context}

Use this context to provide personalized responses."""

    # Generate response
    response = openai_client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[
            {"role": "system", "content": system_prompt},
            {"role": "user", "content": message}
        ]
    )

    assistant_message = response.choices[0].message.content

    # Store the interaction as new memory
    memory.add(
        f"User asked: {message}\nAssistant responded about: {assistant_message[:100]}...",
        user_id=user_id
    )

    return assistant_message
```

### Multi-Agent Memory Scoping

```python
# Separate memories by agent
def get_agent_memory(user_id: str, agent_id: str, query: str):
    return memory.search(
        query,
        user_id=user_id,
        agent_id=agent_id,
        limit=10
    )

# Coding assistant memories
coding_memories = get_agent_memory(
    user_id="user_123",
    agent_id="coding_assistant",
    query="programming preferences"
)

# Support assistant memories
support_memories = get_agent_memory(
    user_id="user_123",
    agent_id="support_assistant",
    query="support history"
)
```

        }
    }
}
```

## Best Practices

### Memory Quality

```python
# DO: Add specific, factual memories
memory.add(
    "User's preferred programming language is Python, specifically for data science",
    user_id="user_123",
    metadata={"confidence": 0.95, "source": "explicit_statement"}
)

# DON'T: Add vague or temporary information
# memory.add("User seems tired today", user_id="user_123")  # Too temporary

# DO: Include context and timestamp for time-sensitive info
memory.add(
    "User is working on a project deadline for Q1 2025",
    user_id="user_123",
    metadata={"valid_until": "2025-03-31", "type": "project"}
)
```

### Memory Retrieval Optimization

```python
# Use specific queries for better retrieval
results = memory.search(
    "programming language preferences for backend development",  # Specific
    user_id="user_123"
)

# Combine multiple focused searches
preferences = memory.search("preferences", user_id="user_123", limit=3)
history = memory.search("past projects", user_id="user_123", limit=3)
skills = memory.search("technical skills", user_id="user_123", limit=3)
```

### Memory Cleanup

```python
# Implement periodic cleanup for stale memories
def cleanup_stale_memories(user_id: str, days_threshold: int = 90):
    from datetime import datetime, timedelta

    all_memories = memory.get_all(user_id=user_id)
    threshold = datetime.now() - timedelta(days=days_threshold)

    for mem in all_memories:
        created_at = datetime.fromisoformat(mem['created_at'])
        if created_at < threshold:
            # Check if memory is still relevant
            if not is_memory_relevant(mem):
                memory.delete(memory_id=mem['id'])
```

## Development Workflow

### Local Development Setup

```bash
# Install mem0
pip install mem0ai

# For specific vector stores
pip install mem0ai[qdrant]
pip install mem0ai[chroma]

# Start local Qdrant (Docker)
docker run -p 6333:6333 qdrant/qdrant

# Or use Chroma (no Docker needed)
pip install chromadb
```

### Testing Memory Operations

```python
import pytest
from mem0 import Memory

@pytest.fixture
def memory_client():
    return Memory()  # In-memory for tests

def test_add_and_retrieve_memory(memory_client):
    # Add memory
    result = memory_client.add(
        "Test memory content",
        user_id="test_user"
    )
    assert result is not None

    # Retrieve memory
    memories = memory_client.get_all(user_id="test_user")
    assert len(memories) > 0
    assert any("Test memory" in m['memory'] for m in memories)

def test_search_relevance(memory_client):
    # Add diverse memories
    memory_client.add("User likes Python programming", user_id="test_user")
    memory_client.add("User enjoys hiking outdoors", user_id="test_user")

    # Search should return relevant results
    results = memory_client.search(
        "programming languages",
        user_id="test_user"
    )

    assert any("Python" in r['memory'] for r in results)
```

## Troubleshooting

### Common Issues

**Memory not found after adding:**
```python
# Ensure you're using the same user_id
result = memory.add("content", user_id="user_123")
# Wait for indexing if using external vector store
import time
time.sleep(1)
memories = memory.get_all(user_id="user_123")  # Same user_id
```

**Poor search results:**
```python
# Use more specific queries
results = memory.search(
    "specific topic with context",
    user_id="user_123",
    limit=10  # Increase limit if needed
)

# Check if memories were indexed with right metadata
all_mems = memory.get_all(user_id="user_123")
print([m['memory'][:50] for m in all_mems])
```

**Vector store connection errors:**
```python
# Verify vector store is running
import requests
try:
    response = requests.get("http://localhost:6333/collections")
    print("Qdrant is running:", response.status_code)
except:
    print("Qdrant not reachable - start with: docker run -p 6333:6333 qdrant/qdrant")
```
