## 🧠 What is Transactive Memory?

In human teams, not everyone remembers everything. Instead, teams develop a **shared awareness of who knows what**:

- *"Sarah handles the legal stuff"*
- *"Mike knows all the technical details"*  
- *"Ask Jennifer about customer history"*

This is called a **Transactive Memory System (TMS)** — a concept from cognitive science that has **never been implemented for AI agents**... until now.

## 💡 Why CogniHive?

Current multi-agent systems fail because:

| Problem | Without CogniHive | With CogniHive |
|---------|-------------------|----------------|
| "Which agent knows X?" | Manual orchestration | `hive.who_knows("topic")` |
| Redundant work | Multiple agents research same thing | Expertise routing prevents duplication |
| Conflicting info | Silent failures | Conflict detection + resolution |
| Token explosion | 15x more tokens (Anthropic's research) | Smart routing = massive savings |

## 🚀 Installation

```bash
pip install cognihive
```

With framework integrations:
```bash
pip install cognihive[crewai]      # For CrewAI
pip install cognihive[autogen]     # For AutoGen
pip install cognihive[langchain]   # For LangChain
pip install cognihive[openai]      # For OpenAI Assistants
pip install cognihive[mcp]         # For Anthropic MCP (Claude)
pip install cognihive[all]         # Everything
```

## ⚡ Quick Start

```python
from cognihive import Hive

# Create a hive (multi-agent memory system)
hive = Hive()

# Register agents with their specializations
hive.register_agent("coder", expertise=["python", "javascript", "testing"])
hive.register_agent("analyst", expertise=["sql", "data", "metrics"])
hive.register_agent("writer", expertise=["docs", "tutorials", "api"])

# Agents store knowledge
hive.remember(
    "Use connection pooling for better DB performance",
    agent="analyst",
    topics=["database", "performance"]
)

# 🔍 THE KEY INNOVATION: "Who Knows What" queries
experts = hive.who_knows("database optimization")
# Returns: [("analyst", 0.92), ("coder", 0.45)]

# 🎯 Automatic query routing to the right expert
result = hive.ask("How do I optimize my queries?")
# Automatically routes to "analyst" and returns relevant memories

print(f"Expert: {result['expert']}")  # "analyst"
print(f"Answer: {result['memories'][0].content}")
```

## 🔗 Integrations

### CrewAI

```python
from crewai import Agent, Crew
from cognihive.integrations import CrewAIHive

hive = CrewAIHive()

researcher = Agent(
    role="Researcher",
    goal="Find information",
    memory=hive.agent_memory("researcher")  # CogniHive memory!
)

writer = Agent(
    role="Writer",
    goal="Write content",
    memory=hive.agent_memory("writer")  # CogniHive memory!
)

# Now agents automatically:
# ✓ Know what each other knows
# ✓ Route questions to the right expert
# ✓ Share learnings across the team
```

### AutoGen

```python
from autogen import AssistantAgent
from cognihive.integrations import AutoGenHive

hive = AutoGenHive()

# Create agents with shared transactive memory
coder = hive.create_memory_enhanced_agent(
    name="coder",
    system_message="You are an expert coder.",
    expertise=["python", "coding"]
)

reviewer = hive.create_memory_enhanced_agent(
    name="reviewer",
    system_message="You review code for quality.",
    expertise=["review", "testing"]
)

# Agents now have collective intelligence!
```

### LangGraph

```python
from cognihive.integrations import LangGraphHive, create_expert_routing_graph

hive = LangGraphHive()
hive.register_agent("researcher", expertise=["research"])
hive.register_agent("writer", expertise=["writing"])

# Create a graph with automatic expert routing
graph = create_expert_routing_graph(
    hive=hive,
    agent_nodes={
        "researcher": researcher_node,
        "writer": writer_node
    }
)
```

### LangChain

```python
from cognihive.integrations import LangChainHive
from langchain.chains import ConversationChain
from langchain_openai import ChatOpenAI

hive = LangChainHive()
hive.register_agent("assistant", expertise=["general"])

# Use CogniHive as LangChain memory
chain = ConversationChain(
    llm=ChatOpenAI(),
    memory=hive.as_memory("assistant")
)

# Or as a retriever for RAG
retriever = hive.as_retriever(top_k=5)
```

### OpenAI Assistants

```python
from openai import OpenAI
from cognihive.integrations import OpenAIHive, create_tool_outputs

client = OpenAI()
hive = OpenAIHive()

# Create assistant with CogniHive tools
assistant = client.beta.assistants.create(
    name="Team Coordinator",
    tools=hive.get_tools(),  # who_knows, remember, recall, ask_expert
    model="gpt-4-turbo"
)

# Process tool calls
outputs = create_tool_outputs(hive, tool_calls)
```

### Anthropic MCP (Claude)

```json
// claude_desktop_config.json
{
  "mcpServers": {
    "cognihive": {
      "command": "python",
      "args": ["-m", "cognihive.integrations.mcp"]
    }
  }
}
```

Claude can now use:
- `cognihive_who_knows` - Find team experts
- `cognihive_remember` - Store knowledge
- `cognihive_recall` - Search memories
- `cognihive_ask_expert` - Route to expert


## 🛠️ CLI

```bash
# Initialize a hive
cognihive init --name my_project

# Register agents
cognihive register coder --expertise python javascript

# Store knowledge
cognihive remember "Important info" --agent coder

# Query "who knows what"
cognihive who-knows "python optimization"

# Search memories
cognihive recall "best practices"

# Run interactive demo
cognihive demo
```

## 📚 Documentation

### Core Concepts

| Concept | Description |
|---------|-------------|
| **Hive** | The central coordinator for multi-agent memory |
| **Agent** | An entity with expertise that stores/retrieves memories |
| **Memory** | A piece of knowledge with provenance and access control |
| **ExpertiseProfile** | Tracks "who knows what" for each agent |
| **ExpertiseRouter** | Routes queries to the best expert |

### Key Methods

```python
# Agent management
hive.register_agent(name, expertise, role)
hive.get_agent(name)
hive.list_agents()

# Memory operations
hive.remember(content, agent, topics, visibility)
hive.recall(query, top_k=5)

# Transactive memory (THE INNOVATION)
hive.who_knows(topic)          # Find experts
hive.get_expert(topic)         # Get best expert
hive.expertise_matrix()        # Get full expertise map

# Query routing
hive.ask(query)                # Auto-route + retrieve
hive.route(query)              # Get routing decision
```

### Memory Visibility

```python
# Private - only the owner sees it
hive.remember("Secret notes", agent="coder", visibility="private")

# Shared - specific agents can see
hive.remember("For the team lead", agent="coder", visibility="shared")

# Team - all agents in the hive can see
hive.remember("Team announcement", agent="coder", visibility="team")
```
