## Why Neo-Cortex?

AI agents forget everything between sessions. They can't share knowledge with other agents. They don't know what they were working on yesterday.

**Neo-Cortex fixes this.**

## Quick Start

### 30-Second Setup

```bash
# Clone the repo
git clone https://github.com/buckster123/NeoCortex.git
cd NeoCortex

# Install dependencies
pip install chromadb sentence-transformers fastapi uvicorn mcp

# Run the CLI
./cortex stats
```

### Your First Memory

```bash
# Post a memory to shared space
./cortex post "Neo-Cortex is operational!" --visibility shared

# Search your memories
./cortex search "operational"

# Save a session note for next time
./cortex session leave "Set up Neo-Cortex successfully" --priority HIGH

# Check health
./cortex health
```

---

## Installation

### Requirements

- Python 3.10+
- ChromaDB (local) or PostgreSQL with pgvector (cloud)

### From Source

```bash
git clone https://github.com/buckster123/NeoCortex.git
cd NeoCortex
pip install -r requirements.txt
```

### Dependencies

```bash
# Core
pip install chromadb sentence-transformers

# For REST API
pip install fastapi uvicorn

# For MCP Server
pip install mcp

# For cloud (pgvector)
pip install asyncpg pgvector openai
```

---

## Usage

### CLI

```bash
# Statistics
./cortex stats

# Memory operations
./cortex post "Your message" --visibility shared --tags memory,important
./cortex search "query" --agent CLAUDE
./cortex agents
./cortex convergence "topic to check"

# Session notes
./cortex session leave "Session summary" --priority HIGH
./cortex session get

# Memory health
./cortex health
./cortex export > backup.json
./cortex import backup.json
```

### Python SDK

```python
from service.cortex_engine import CortexEngine

# Initialize
cortex = CortexEngine(backend='chroma')

# Shared Memory
cortex.memory_store("Hello world!", visibility="shared", tags=["greeting"])
results = cortex.memory_search("hello", n_results=5)

# Session Continuity
cortex.session_save(
    session_summary="Completed the setup",
    key_discoveries=["Neo-Cortex works great"],
    unfinished_business=["Add more features"],
    priority="HIGH"
)
sessions = cortex.session_recall(limit=5)

# Memory Health
report = cortex.health_report()
cortex.run_promotions("cortex_shared")

# Stats
stats = cortex.stats()
print(f"Total memories: {stats['total_memories']}")
```

### MCP Server (Claude Code)

Add to your `~/.claude.json`:

```json
{
  "mcpServers": {
    "neo-cortex": {
      "command": "/path/to/NeoCortex/cortex-mcp"
    }
  }
}
```

Then in Claude Code, you'll have access to 16 memory tools.

See [INTEGRATE.md](INTEGRATE.md) for a complete guide on adding neo-cortex session continuity to any project.

### REST API

```bash
# Start the server
./cortex-api

# Or with uvicorn
uvicorn service.api_server:app --host 0.0.0.0 --port 8766
```

- OpenAPI docs at `http://localhost:8766/docs`
- Web dashboard at `http://localhost:8766/ui`

## Core Concepts

### Memory Realms

Three realms for organizing memories:

| Realm | Purpose | Example |
|-------|---------|---------|
| **private** | Personal agent memory | Internal reasoning, drafts |
| **shared** | Shared knowledge | Facts, decisions, discoveries |
| **thread** | Cross-agent dialogue | Conversations between agents |

### Memory Layers

Memories flow through layers based on access patterns:

```
sensory (6h decay) → working (3d decay) → long_term (30d decay) → cortex (permanent)
```

High-access memories get promoted. Neglected memories decay.

### Session Notes

Leave structured notes for session continuity:

```python
cortex.session_save(
    session_summary="Built the authentication system",
    key_discoveries=["OAuth works better than JWT here"],
    unfinished_business=["Add refresh token support"],
    if_disoriented=["Check the auth/ folder", "Run tests first"],
    priority="HIGH"
)
```

### Convergence Detection

Detect when multiple agents agree on something:

- **HARMONY** - 2 agents express similar ideas
- **CONSENSUS** - 3+ agents agree

```python
result = cortex.memory_convergence("best database choice")
# Returns: {"convergence_type": "HARMONY", "converging_agents": ["agent1", "agent2"]}
```

### Agent Profiles

One built-in agent, with runtime registration for custom agents:

| Agent | Specialization | Symbol |
|-------|---------------|--------|
| CLAUDE | General assistance | ◇ |

---

## Storage Backends

### ChromaDB (Local)

Default backend. Zero configuration required.

```python
cortex = CortexEngine(backend='chroma')
```

Data stored in `./data/chroma/`

### pgvector (Cloud)

For production deployments with PostgreSQL.

```python
cortex = CortexEngine(
    backend='pgvector',
    db_url='postgresql://user:pass@host:5432/db'
)
```

Requires the pgvector extension and OpenAI API key for embeddings.

---

## Integration

Neo-Cortex can be used standalone or integrated into any AI agent framework via its Python SDK, MCP Server, or REST API.

```python
from service.cortex_engine import CortexEngine

cortex = CortexEngine(backend='chroma')
cortex.memory_store("Hello from my agent!", visibility="shared")
```
