X Integration

Before using this skill, ensure:

1. NanoClaw is installed and running - WhatsApp connected, service active
2. Dependencies installed:

   npm ls playwright dotenv-cli || npm install playwright dotenv-cli
   

3. CHROME_PATH configured in .env (if Chrome is not at default location):

   # Find your Chrome path
   mdfind "kMDItemCFBundleIdentifier == 'com.google.Chrome'" 2>/dev/null | head -1
   # Add to .env
   CHROME_PATH=/path/to/Google Chrome.app/Contents/MacOS/Google Chrome
   

Quick Start

# 1. Setup authentication (interactive)
npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts
# Verify: data/x-auth.json should exist after successful login

# 2. Rebuild container to include skill
./container/build.sh
# Verify: Output shows "COPY .claude/skills/x-integration/agent.ts"

# 3. Rebuild host and restart service
npm run build
launchctl kickstart -k gui/$(id -u)/com.nanoclaw  # macOS
# Linux: systemctl --user restart nanoclaw
# Verify: launchctl list | grep nanoclaw (macOS) or systemctl --user status nanoclaw (Linux)

Configuration

Environment Variables

Set in .env file (loaded via dotenv-cli at runtime):

# .env
CHROME_PATH=/Applications/Google Chrome.app/Contents/MacOS/Google Chrome

Configuration File

Edit lib/config.ts to modify defaults:

export const config = {
    // Browser viewport
    viewport: { width: 1280, height: 800 },

    // Timeouts (milliseconds)
    timeouts: {
        navigation: 30000,    // Page navigation
        elementWait: 5000,    // Wait for element
        afterClick: 1000,     // Delay after click
        afterFill: 1000,      // Delay after form fill
        afterSubmit: 3000,    // Delay after submit
        pageLoad: 3000,       // Initial page load
    },

    // Tweet limits
    limits: {
        tweetMaxLength: 280,
    },
};

Why This Design?

• API is expensive - X official API requires paid subscription ($100+/month) for posting
• Bot browsers get blocked - X detects and bans headless browsers and common automation fingerprints
• Must use user's real browser - Reuses the user's actual Chrome on Host with real browser fingerprint to avoid detection
• One-time authorization - User logs in manually once, session persists in Chrome profile for future use

Integration Points

To integrate this skill into NanoClaw, make the following modifications:

1. Host side: src/ipc.ts

Add import after other local imports:

import { handleXIpc } from '../.claude/skills/x-integration/host.js';

Modify processTaskIpc function's switch statement default case:

// Find:
