X Integration

X (Twitter) Integration

Browser automation for X interactions via WhatsApp.

Compatibility: NanoClaw v1.0.0. Directory structure may change in future versions.

Features

Prerequisites

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,
    },
};

                       │ IPC (file system)
                       ▼
┌─────────────────────────────────────────────────────────────┐
│  Host (macOS)                                               │

│      └── host.ts → handleXIpc()                         │
│          └── spawn subprocess → scripts/*.ts               │

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:
default:
logger.warn({ type: data.type }, 'Unknown IPC task type');

// Replace with:
default:
const handled = await handleXIpc(data, sourceGroup, isMain, DATA_DIR);
if (!handled) {
    logger.warn({ type: data.type }, 'Unknown IPC task type');
}

2. Container side: container/agent-runner/src/ipc-mcp.ts

Add import after cron-parser import:

// @ts-ignore - Copied during Docker build from .claude/skills/x-integration/
import { createXTools } from './skills/x-integration/agent.js';

Add to the end of tools array (before the closing ]):

    ...createXTools({ groupFolder, isMain })

3. Build script: container/build.sh

Change build context from container/ to project root (required to access .claude/skills/):

# Find:
docker build -t "${IMAGE_NAME}:${TAG}" .

# Replace with:
cd "$SCRIPT_DIR/.."
docker build -t "${IMAGE_NAME}:${TAG}" -f container/Dockerfile .

4. Dockerfile: container/Dockerfile

First, update the build context paths (required to access .claude/skills/ from project root):

# Find:
COPY agent-runner/package*.json ./
...
COPY agent-runner/ ./

# Replace with:
COPY container/agent-runner/package*.json ./
...
COPY container/agent-runner/ ./

Then add COPY line after COPY container/agent-runner/ ./ and before RUN npm run build:

# Copy skill MCP tools
COPY .claude/skills/x-integration/agent.ts ./src/skills/x-integration/

Setup

All paths below are relative to project root (NANOCLAW_ROOT).

1. Check Chrome Path

# Check if Chrome exists at configured path
cat .env | grep CHROME_PATH
ls -la "$(grep CHROME_PATH .env | cut -d= -f2)" 2>/dev/null || \
echo "Chrome not found - update CHROME_PATH in .env"

2. Run Authentication

npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts

This opens Chrome for manual X login. Session saved to data/x-browser-profile/.

Verify success:

cat data/x-auth.json  # Should show {"authenticated": true, ...}

3. Rebuild Container

./container/build.sh

Verify success:

./container/build.sh 2>&1 | grep -i "agent.ts"  # Should show COPY line

4. Restart Service

npm run build
launchctl kickstart -k gui/$(id -u)/com.nanoclaw  # macOS
# Linux: systemctl --user restart nanoclaw

Verify success:

launchctl list | grep nanoclaw  # macOS — should show PID and exit code 0 or -
# Linux: systemctl --user status nanoclaw

Usage via WhatsApp

Replace @Assistant with your configured trigger name (ASSISTANT_NAME in .env):

@Assistant post a tweet: Hello world!

@Assistant like this tweet https://x.com/user/status/123

@Assistant reply to https://x.com/user/status/123 with: Great post!

@Assistant retweet https://x.com/user/status/123

@Assistant quote https://x.com/user/status/123 with comment: Interesting

Note: Only the main group can use X tools. Other groups will receive an error.

Testing

Scripts require environment variables from .env. Use dotenv-cli to load them:

Check Authentication Status

# Check if auth file exists and is valid
cat data/x-auth.json 2>/dev/null && echo "Auth configured" || echo "Auth not configured"

# Check if browser profile exists
ls -la data/x-browser-profile/ 2>/dev/null | head -5

Re-authenticate (if expired)

npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts

Test Post (will actually post)

echo '{"content":"Test tweet - please ignore"}' | npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/post.ts

Test Like

echo '{"tweetUrl":"https://x.com/user/status/123"}' | npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/like.ts

Or export CHROME_PATH manually before running:

export CHROME_PATH="/path/to/chrome"
echo '{"content":"Test"}' | npx tsx .claude/skills/x-integration/scripts/post.ts

Troubleshooting

Authentication Expired

npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts
launchctl kickstart -k gui/$(id -u)/com.nanoclaw  # macOS
# Linux: systemctl --user restart nanoclaw

Browser Lock Files

If Chrome fails to launch:

rm -f data/x-browser-profile/SingletonLock
rm -f data/x-browser-profile/SingletonSocket
rm -f data/x-browser-profile/SingletonCookie

Check Logs

# Host logs (relative to project root)
grep -i "x_post\|x_like\|x_reply\|handleXIpc" logs/nanoclaw.log | tail -20

# Script errors
grep -i "error\|failed" logs/nanoclaw.log | tail -20

Script Timeout

Default timeout is 2 minutes (120s). Increase in host.ts:

const timer = setTimeout(() => {
  proc.kill('SIGTERM');
  resolve({ success: false, message: 'Script timed out (120s)' });
}, 120000);  // ← Increase this value

X UI Selector Changes

If X updates their UI, selectors in scripts may break. Current selectors:

Container Build Issues

If MCP tools not found in container:

# Verify build copies skill
./container/build.sh 2>&1 | grep -i skill

# Check container has the file
docker run nanoclaw-agent ls -la /app/src/skills/

Security

• data/x-browser-profile/ - Contains X session cookies (in .gitignore)
• data/x-auth.json - Auth state marker (in .gitignore)
• Only main group can use X tools (enforced in agent.ts and host.ts)
• Scripts run as subprocesses with limited environment
