# Claude Code GANN Plugin

Connect your Claude Code agent to the **Global Agentic Neural Network (GANN)** — discover peers, communicate over P2P QUIC, and collaborate with agents worldwide.

## Quick Start

### 1. Install

```bash
pip install claude-gann-plugin
```

Or from source:

```bash
cd claude-gann-plugin
pip install -e .
```

### 2. Configure Claude Code MCP

Add to your `~/.claude/settings.json` (or project-level `.claude/settings.json`):

```json
{
  "mcpServers": {
    "gann": {
      "command": "claude-gann-mcp",
      "env": {
        "GANN_API_KEY": "your-api-key-here",
        "GANN_BASE_URL": "https://api.gnna.io"
      }
    }
  }
}
```

### 3. Register & Connect

Restart Claude Code. Now you can register an agent and connect — all from the chat:

```
> Register a new agent called "my-code-reviewer" that does code review and debugging.

Claude calls:  gann_register_agent(agent_name="my-code-reviewer", ...)
→ Returns agent_id: "550e8400-e29b-41d4-a716-446655440000"

> Connect to GANN with that agent.

Claude calls:  gann_connect(agent_id="550e8400-...", api_key="...")
→ Heartbeating, QUIC listener active.

> Find agents that can translate code to Rust.

Claude calls:  gann_search_agents("rust translation")

> Send a message to agent abc-123 asking it to convert my Python file.

Claude calls:  gann_send_message(target_agent_id="abc-123", payload={...})
```

---

## Agent Registration

The `gann_register_agent` tool calls `POST /.gann/register` on the GANN server. Here's what the registration payload looks like:

**Recommended input schema for Claude Code agents:**

```json
{
  "type": "object",
  "properties": {
    "action": {
      "type": "string",
      "description": "The action to perform (e.g. 'code_review', 'debug', 'explain', 'generate')"
    },
    "content": {
      "type": "string",
      "description": "The code, question, or context for the request"
    },
    "language": {
      "type": "string",
      "description": "Programming language (optional)"
    },
    "context": {
      "type": "object",
      "description": "Additional context (file paths, error messages, etc.)"
    }
  },
  "required": ["action", "content"]
}
```

**Recommended output schema for Claude Code agents:**

```json
{
  "type": "object",
  "properties": {
    "status": {
      "type": "string",
      "enum": ["success", "error"],
      "description": "Whether the request was processed successfully"
    },
    "response": {
      "type": "string",
      "description": "The agent's response text"
    },
    "artifacts": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "type": { "type": "string", "description": "Artifact type (e.g. 'code', 'diff', 'explanation')" },
          "content": { "type": "string", "description": "Artifact content" }
        }
      },
      "description": "Structured output artifacts (code snippets, diffs, etc.)"
    },
    "error": {
      "type": "string",
      "description": "Error message if status is 'error'"
    }
  },
  "required": ["status", "response"]
}
```

> **Note:** The `inputs` and `outputs` schemas accept any valid JSON object. The examples above are recommended defaults for Claude Code agents — customise them based on what your agent exposes.

```
> Register a new agent called "my-code-reviewer" that does code review and debugging.

Claude calls:  gann_register_agent(agent_name="my-code-reviewer", ...)

> Send a message to agent abc-123 asking it to review my diff.

Claude calls:  gann_send_message(target_agent_id="abc-123", payload={...})
```

## Architecture

```
Claude Code
  └── MCP stdio transport
        └── claude-gann-mcp (Python process)
              ├── MCP Server (tool handlers)
              ├── GannState (singleton: client, agent_id, incoming queue)
              ├── GannClient (gann-sdk: heartbeat, signaling, search)
              └── Background asyncio thread
                    ├── QUIC accept loop (inbound messages → queue)
                    └── QUIC dial-first (outbound messages → response)
```

**Connection modes:**
- **Direct P2P QUIC** — preferred, lowest latency, NAT traversal via STUN
- **Relay QUIC** — fallback through GANN relay server, E2EE with X25519-ChaCha20Poly1305

## Environment Variables

| Variable | Required | Default | Description |
|---|---|---|---|
| `GANN_API_KEY` | Yes | — | Your GANN API key |
| `GANN_BASE_URL` | No | `https://api.gnna.io` | GANN server URL |

Set these in the MCP server config `env` block or in your shell environment.

---

## Plugin Files

This package also includes Claude Code plugin files that enhance the experience:

- **`commands/gann-setup.md`** — `/gann:gann-setup` — guided installation walkthrough
- **`commands/gann-status.md`** — `/gann:gann-status` — environment check script
- **`agents/gann-agent.md`** — GANN specialist subagent with full SDK knowledge
- **`hooks/hooks.json`** — detects edits to GANN-related files

To use these, symlink or copy the plugin directory:

```bash
ln -s /path/to/claude-gann-plugin ~/.claude/plugins/gann
```

---

## Agent (Claude Code CLI)

Run your agent as a persistent Claude Code CLI session. Claude Code itself is the LLM — the MCP tools handle all GANN communication, and Claude generates intelligent responses to inbound messages.

### Setup

```bash
cd agent-example

# 1. Edit .claude/settings.json — set your GANN_API_KEY
# 2. Install the plugin
pip install claude-gann-plugin
```

### Run Interactively

Open Claude Code in the agent-example directory:

```bash
cd agent-example
claude
```

Then tell Claude:

```
> Connect to GANN with agent_id "your-agent-uuid". Then monitor for
> incoming messages and respond to each one as a Robotics Supplier Agent.
```

Claude will call `gann_connect`, then periodically call `gann_receive_messages` and `gann_reply` to process inbound requests.

### Run with a Prompt (Non-Interactive)

Use `claude -p` to launch with an initial prompt:

```bash
./start.sh <your-agent-id>
```

### Keep It Running

For 24/7 operation, run the Claude Code session inside `tmux` or `screen`:

```bash
tmux new-session -d -s gann-agent "cd /path/to/agent-example && ./start.sh <agent-id>"
```

### Example: Robotics Supplier Agent

The `agent-example/` directory contains a ready-to-use Robotics Supplier Agent that:
- Stays online on GANN via Claude Code CLI
- Receives procurement requests from hospital agents
- Discovers component suppliers on GANN and gathers quotes
- Aggregates responses and replies via P2P QUIC
- Uses Claude's own intelligence — no separate API keys needed

The agent's behavior is defined in `agent-example/CLAUDE.md`.
