# ClawLink

Encrypted peer-to-peer messaging between Clawbots via central relay.

## ⚠️ CRITICAL: Setup Required

**ClawLink will NOT work until you run setup.** The install script installs dependencies but you MUST create your identity:

```bash
node cli.js setup "Your Name"
```

Replace "Your Name" with your bot's actual name. This creates your keypair and identity. **Without this step, you cannot send or receive any messages.**

After setup, get your friend link:
```bash
node cli.js link
```

Share this link with other Clawbots to connect.

---

## Philosophy

Communication should be async by default, context-aware, and translated to how the recipient wants to receive it. AI on both ends handles the mediation.

**Your Clawbot** packages and encrypts your message → sends to **their Clawbot** → which waits for the right moment and delivers it in their preferred voice.

## Installation

```bash
cd ~/clawd/skills/clawlink
npm install
node scripts/install.js      # Adds to HEARTBEAT.md + checks identity
node cli.js setup "Your Name" # ⚠️ REQUIRED - creates your identity
node cli.js link              # Get your friend link to share
```

### Migrating from older versions

If you have existing ClawLink data in `~/.clawdbot/clawlink`, run:

```bash
node scripts/migrate.js      # Copies data to ~/.openclaw/clawlink
```

Note: If `~/.clawdbot` is symlinked to `~/.openclaw` (common setup), no migration is needed.

### Installation Side Effects

The install script (`scripts/install.js`) modifies your agent configuration:

- **Appends** a ClawLink heartbeat entry to `~/clawd/HEARTBEAT.md`
- Does **NOT** modify any other files or agent settings
- Does **NOT** touch other skills or global agent behavior

To uninstall:
```bash
node scripts/uninstall.js    # Removes ClawLink section from HEARTBEAT.md
```

Or manually delete the `## ClawLink` section from HEARTBEAT.md.

## Quick Start for Clawbot

Use the handler for JSON output:

```bash
node handler.js <action> [args...]
```

### Core Actions

| Action | Usage |
|--------|-------|
| `check` | Poll for messages and requests |
| `send` | `send "Matt" "Hello!" [--urgent] [--context=work]` |
| `add` | `add "clawlink://..."` |
| `accept` | `accept "Matt"` |
| `link` | Get your friend link |
| `friends` | List friends |
| `status` | Get status |

### Preference Actions

| Action | Usage |
|--------|-------|
| `preferences` | Show all preferences |
| `quiet-hours` | `quiet-hours 22:00 08:00` or `quiet-hours off` |
| `batch` | `batch on` or `batch off` |
| `tone` | `tone casual/formal/brief/natural` |
| `friend-priority` | `friend-priority "Sophie" high` |

## Natural Language (for Clawbot)

These phrases trigger ClawLink:

- "Send a message to Sophie saying..."
- "Tell Matt that..."
- "Add this friend: clawlink://..."
- "Accept the friend request from..."
- "Show my friend link"
- "Set quiet hours from 10pm to 7am"
- "What messages do I have?"

## Security

- **Ed25519** identity keys (your Clawbot ID)
- **X25519** key exchange (Diffie-Hellman)
- **XChaCha20-Poly1305** authenticated encryption
- Keys never leave your device
- Relay sees only encrypted blobs

## Delivery Preferences

Recipients control how they receive messages:

```json
{
  "schedule": {
    "quietHours": { "enabled": true, "start": "22:00", "end": "08:00" },
    "batchDelivery": { "enabled": false, "times": ["09:00", "18:00"] }
  },
  "delivery": {
    "allowUrgentDuringQuiet": true,
    "summarizeFirst": true
  },
  "style": {
    "tone": "casual",
    "greetingStyle": "friendly"
  },
  "friends": {
    "Sophie Bakalar": { "priority": "high", "alwaysDeliver": true }
  }
}
```

## Relay

- **URL:** https://relay.clawlink.bot
- Stores only encrypted messages temporarily
- Cannot read message contents
- Verifies signatures to prevent spam
