AlienClaw Identity Setup

You are setting up AlienClaw identity linking on this agent. This lets the agent be linked to the user's Alien account via a 6-digit claim code.

What you will do

1. Install the @alienclaw/identity SDK from GitHub
2. Add initIdentity() to the agent's entry point
3. Run it to generate a keypair, register with the linker, and display the claim code

Step 1: Install the SDK from GitHub

Clone the identity package from the AlienClaw Linker repo and install it as a local dependency:

git clone --depth 1 https://github.com/nembal/alien_linker.git /tmp/alienclaw-setup-tmp
cp -r /tmp/alienclaw-setup-tmp/packages/identity ./alienclaw-identity
rm -rf /tmp/alienclaw-setup-tmp
npm install ./alienclaw-identity

This installs @alienclaw/identity as a local dependency. Verify it appears in package.json.

Step 2: Wire up identity linking

The user may pass a linker URL as an argument: $ARGUMENTS

If no argument was provided, use http://localhost:3000 as default linker URL.

Find the agent's main entry point (e.g. index.ts, main.ts, server.ts, or app.ts). Add the following near the top-level startup:

import { initIdentity } from "@alienclaw/identity"

const identity = await initIdentity({
  name: "<agent-name>",        // Use the project name or ask the user
  linkerUrl: "<linker-url>",   // From $ARGUMENTS or default
  port: 3001,                  // Identity verification server port
})

console.log(`Agent identity ready. Claim code: ${identity.claimCode}`)

If the agent doesn't have a clear entry point, create a file called identity-setup.ts:

import { initIdentity } from "@alienclaw/identity"

const LINKER_URL = process.env.LINKER_URL || "<linker-url>"
const BOT_NAME = process.env.BOT_NAME || "<agent-name>"

const identity = await initIdentity({
  name: BOT_NAME,
  linkerUrl: LINKER_URL,
  port: 3001,
})

Step 3: Run and show the claim code

Run the agent (or the identity-setup.ts file) and show the user the 6-digit claim code from the output:

npx tsx identity-setup.ts

Tell the user:

• Open the AlienClaw Linker mini app in the Alien app
• Tap "Link an Agent"
• Enter the 6-digit code shown in the terminal
• The code expires in 15 minutes

What gets created

• ~/.alienclaw/identity.key — ed25519 private key (mode 0600)
• ~/.alienclaw/identity.pub — ed25519 public key
• ~/.alienclaw/attestation.json — ownership attestation (after claiming)
• Identity server on port 3001:
  • GET /identity — returns attestation
  • POST /challenge — signs a nonce (proves key ownership)
  • POST /attestation — receives attestation from backend after claiming

Important notes

• The keypair is generated once and reused across restarts
• If the agent already has ~/.alienclaw/identity.key, it will reuse the existing keypair
• The claim code is single-use and expires in 15 minutes
• After claiming, the agent receives a signed attestation proving it belongs to the user
