# 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.

## 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
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")
```
