ClawLink

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

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

cd ~/clawd/skills/clawlink
npm install
node scripts/install.js      # Adds to HEARTBEAT.md
node cli.js setup "Your Name"

Quick Start for Clawbot

Use the handler for JSON output:

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:

{
  "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 }
  }
}
