/lastid-claude-guard:register — Link Your DID

Arguments: $ARGUMENTS

The CLI is at ${CLAUDE_PLUGIN_ROOT}/bin/guard-cli.ts. All commands return JSON.

---

Step 1: Check current state

bun ${CLAUDE_PLUGIN_ROOT}/bin/guard-cli.ts status

If registeredDid is set, tell the user they're already registered and show the DID. Ask if they want to re-register.

Step 2: Collect SDK client_id (if needed)

If clientId is null, ask the user for their SDK client_id (from https://human.lastid.co — free tier: 1 key).

bun ${CLAUDE_PLUGIN_ROOT}/bin/guard-cli.ts save-config '{"clientId":"USER_KEY_HERE","enabled":true}'

Step 3: Create verification request

bun ${CLAUDE_PLUGIN_ROOT}/bin/guard-cli.ts request

This creates the request, prints JSON with { requestId, deepLink, expiresIn }, AND renders a QR code in the terminal.

IMPORTANT: Show the FULL output to the user — the QR code IS the registration interface. Tell them to scan it with the LastID app.

Step 4: Send deep link via messaging channel

If imessageChatId is configured, send the deep link via mcp__imessage__reply. If Telegram or Discord is available, use those instead. This is the tap-to-verify backup for when the user is on their phone:

LastID Registration — Tap to verify your identity:
<deepLink from step 3>
Request: <first 8 chars of requestId>
Expires in 5 minutes.

Step 5: Wait and complete registration

bun ${CLAUDE_PLUGIN_ROOT}/bin/guard-cli.ts complete <requestId from step 3>

This blocks until the user presents their credential, then automatically:

• Decodes the subject DID from the verified presentation
• Saves it to config

Tell the user to scan the QR or tap the link while this runs.

Step 6: Confirm

When complete returns, show the registered DID. Tell the user:

• Their DID is registered
• The guard is active for remote sessions (iMessage, Telegram, Discord)
• Check status with /lastid-claude-guard:status

Errors

• SDK not installed: cd ${CLAUDE_PLUGIN_ROOT} && bun install
• Request expires: re-run from step 3
