Prerequisites
Before using this skill, ensure:
- NanoClawbster is installed and running - WhatsApp connected, service active
- Dependencies installed:
bash
1npm ls playwright dotenv-cli || npm install playwright dotenv-cli
- CHROME_PATH configured in
.env (if Chrome is not at default location):
bash
1# Find your Chrome path
2mdfind "kMDItemCFBundleIdentifier == 'com.google.Chrome'" 2>/dev/null | head -1
3# Add to .env
4CHROME_PATH=/path/to/Google Chrome.app/Contents/MacOS/Google Chrome
Quick Start
bash
1# 1. Setup authentication (interactive)
2npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts
3# Verify: data/x-auth.json should exist after successful login
4
5# 2. Rebuild container to include skill
6./container/build.sh

Architecture
┌─────────────────────────────────────────────────────────────┐
│ Container (Linux VM) │
│ └── agent.ts → MCP tool definitions (x_post, etc.) │
│ └── Writes IPC request to /workspace/ipc/tasks/ │
└──────────────────────┬──────────────────────────────────────┘
│ IPC (file system)
▼
┌─────────────────────────────────────────────────────────────┐
│ Host (macOS) │
│ └── src/ipc.ts → processTaskIpc() │
│ └── host.ts → handleXIpc() │
│ └── spawn subprocess → scripts/*.ts │
│ └── Playwright → Chrome → X Website │
└─────────────────────────────────────────────────────────────┘
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 NanoClawbster, make the following modifications:
1. Host side: src/ipc.ts
Add import after other local imports:
typescript
1import { handleXIpc } from '../.claude/skills/x-integration/host.js';
Modify processTaskIpc function's switch statement default case:
typescript
1// Find:
2default:
3logger.warn({ type: data.type }, 'Unknown IPC task type');
4
5// Replace with:
6default:
7const handled = await handleXIpc(data, sourceGroup, isAdmin, DATA_DIR);
8if (!handled) {
9 logger.warn({ type: data.type }, 'Unknown IPC task type');
10}
2. Container side: container/agent-runner/src/ipc-mcp.ts
Add import after cron-parser import:
typescript
1// @ts-ignore - Copied during Docker build from .claude/skills/x-integration/
2import { createXTools } from './skills/x-integration/agent.js';
Add to the end of tools array (before the closing ]):
typescript
1 ...createXTools({ groupFolder, isAdmin })
3. Build script: container/build.sh
Change build context from container/ to project root (required to access .claude/skills/):
bash
1# Find:
2docker build -t "${IMAGE_NAME}:${TAG}" .
3
4# Replace with:
5cd "$SCRIPT_DIR/.."
6docker build -t "${IMAGE_NAME}:${TAG}" -f container/Dockerfile .
4. Dockerfile: container/Dockerfile
First, update the build context paths (required to access .claude/skills/ from project root):
dockerfile
1# Find:
2COPY agent-runner/package*.json ./
3...
4COPY agent-runner/ ./
5
6# Replace with:
7COPY container/agent-runner/package*.json ./
8...
9COPY container/agent-runner/ ./
Then add COPY line after COPY container/agent-runner/ ./ and before RUN npm run build:
dockerfile
1# Copy skill MCP tools
2COPY .claude/skills/x-integration/agent.ts ./src/skills/x-integration/
Setup
All paths below are relative to project root (NANOCLAWBSTER_ROOT).
1. Check Chrome Path
bash
1# Check if Chrome exists at configured path
2cat .env | grep CHROME_PATH
3ls -la "$(grep CHROME_PATH .env | cut -d= -f2)" 2>/dev/null || \
4echo "Chrome not found - update CHROME_PATH in .env"
2. Run Authentication
bash
1npx 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:
bash
1cat data/x-auth.json # Should show {"authenticated": true, ...}
3. Rebuild Container
bash
1./container/build.sh
Verify success:
bash
1./container/build.sh 2>&1 | grep -i "agent.ts" # Should show COPY line
4. Restart Service
bash
1npm run build
2launchctl kickstart -k gui/$(id -u)/com.nanoclawbster # macOS
3# Linux: systemctl --user restart nanoclawbster
Verify success:
bash
1launchctl list | grep nanoclawbster # macOS — should show PID and exit code 0 or -
2# Linux: systemctl --user status nanoclawbster
Usage via WhatsApp
Replace @Assistant with your configured trigger name (ASSISTANT_NAME in .env):
@Assistant post a tweet: Hello world!
@Assistant like this tweet https://x.com/user/status/123
@Assistant reply to https://x.com/user/status/123 with: Great post!
@Assistant retweet https://x.com/user/status/123
@Assistant quote https://x.com/user/status/123 with comment: Interesting
Note: Only the main group can use X tools. Other groups will receive an error.
Testing
Scripts require environment variables from .env. Use dotenv-cli to load them:
Check Authentication Status
bash
1# Check if auth file exists and is valid
2cat data/x-auth.json 2>/dev/null && echo "Auth configured" || echo "Auth not configured"
3
4# Check if browser profile exists
5ls -la data/x-browser-profile/ 2>/dev/null | head -5
Re-authenticate (if expired)
bash
1npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts
Test Post (will actually post)
bash
1echo '{"content":"Test tweet - please ignore"}' | npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/post.ts
Test Like
bash
1echo '{"tweetUrl":"https://x.com/user/status/123"}' | npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/like.ts
Or export CHROME_PATH manually before running:
bash
1export CHROME_PATH="/path/to/chrome"
2echo '{"content":"Test"}' | npx tsx .claude/skills/x-integration/scripts/post.ts
Troubleshooting
Authentication Expired
bash
1npx dotenv -e .env -- npx tsx .claude/skills/x-integration/scripts/setup.ts
2launchctl kickstart -k gui/$(id -u)/com.nanoclawbster # macOS
3# Linux: systemctl --user restart nanoclawbster
Browser Lock Files
If Chrome fails to launch:
bash
1rm -f data/x-browser-profile/SingletonLock
2rm -f data/x-browser-profile/SingletonSocket
3rm -f data/x-browser-profile/SingletonCookie
Check Logs
bash
1# Host logs (relative to project root)
2grep -i "x_post\|x_like\|x_reply\|handleXIpc" logs/nanoclawbster.log | tail -20
3
4# Script errors
5grep -i "error\|failed" logs/nanoclawbster.log | tail -20
Script Timeout
Default timeout is 2 minutes (120s). Increase in host.ts:
typescript
1const timer = setTimeout(() => {
2 proc.kill('SIGTERM');
3 resolve({ success: false, message: 'Script timed out (120s)' });
4}, 120000); // ← Increase this value
X UI Selector Changes
If X updates their UI, selectors in scripts may break. Current selectors:
| Element | Selector |
|---|
| Tweet input | [data-testid="tweetTextarea_0"] |
| Post button | [data-testid="tweetButtonInline"] |
| Reply button | [data-testid="reply"] |
| Like | [data-testid="like"] |
| Unlike | [data-testid="unlike"] |
| Retweet | [data-testid="retweet"] |
| Unretweet | [data-testid="unretweet"] |
| Confirm retweet | [data-testid="retweetConfirm"] |
| Modal dialog | [role="dialog"][aria-modal="true"] |
| Modal submit | [data-testid="tweetButton"] |
Container Build Issues
If MCP tools not found in container:
bash
1# Verify build copies skill
2./container/build.sh 2>&1 | grep -i skill
3
4# Check container has the file
5docker run nanoclawbster-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
