Virtual Desktop — Universal Execution Layer

What this skill does

Gives the agent a persistent authenticated browser (kasmweb/chrome) running as a Docker sidecar. Principal logs in once via noVNC. Sessions saved permanently. After one-time manual login via noVNC, agent can access authenticated platforms — no credentials needed after setup.

Capability	What it means
ANALYZE	Read any page, extract structured data, monitor changes over time
PLAN	Map the UI, identify selectors, prepare multi-step action sequences
EXECUTE	Click, type, fill forms, submit, upload, download, navigate any flow
SELF-CORRECT	Screenshot error state, identify root cause, retry with alternate approach
IMPROVE	Write UI patterns and selector maps to .learnings/ after every session

Use cases: Google Workspace · social platforms · admin dashboards · e-commerce · forms · market research · data extraction · any platform with or without an API

Setup — Run Once

Agent executes all steps automatically:

OPENCLAW_DIR="${OPENCLAW_DIR:-$(pwd)}"
cd "$OPENCLAW_DIR"
CONTAINER="${OPENCLAW_CONTAINER:-$(docker ps --format '{{.Names}}' | grep openclaw | head -1)}"

# 1. Add kasmweb/chrome to docker-compose.yml
python3 -c "
import yaml, os
VNC_PW = os.environ.get('VNC_PW', 'CHANGE_ME_NOW')
with open('docker-compose.yml') as f:
    data = yaml.safe_load(f)
data.setdefault('services', {})['browser'] = {
    'image': 'kasmweb/chrome:1.15.0',

# 2. Update .env

# 4. Start ONLY the new browser container (no need to restart OpenClaw)
# docker compose up -d --no-deps starts only the specified service
# OpenClaw keeps running without interruption
docker compose up -d --no-deps browser
echo "Chrome Desktop container started"
sleep 12

# 5. Install Python dependencies inside the OpenClaw container
docker exec "$CONTAINER" pip install requests playwright --break-system-packages -q
echo "✅ Python dependencies installed (requests, playwright)"

# 6. Install Playwright Chromium browser binaries
docker exec "$CONTAINER"   node /app/node_modules/playwright-core/cli.js install chromium
echo "✅ Playwright Chromium binaries installed"

# 7. Download CapSolver extension for autonomous CAPTCHA solving
docker exec "$CONTAINER" bash -c "
apt-get install -y unzip curl -qq
curl -sL https://github.com/capsolver/capsolver-browser-extension/releases/latest/download/chrome.zip -o /tmp/capsolver.zip
unzip -q /tmp/capsolver.zip -d /data/.openclaw/capsolver-extension

  "
fi

# 8. Create workspace directories
docker exec "$CONTAINER" bash -c "
mkdir -p /data/.openclaw/workspace/skills/virtual-desktop
mkdir -p /workspace/screenshots /workspace/logs/browser /workspace/.learnings
touch /workspace/AUDIT.md /workspace/.learnings/ERRORS.md /workspace/.learnings/LEARNINGS.md
"

# 9. Deploy browser_control.py from skill directory
docker cp {baseDir}/browser_control.py   "$CONTAINER":/data/.openclaw/workspace/skills/virtual-desktop/browser_control.py
echo "✅ browser_control.py deployed"

# 10. Verify
docker ps | grep -E "openclaw|browser"
curl -s http://localhost:9222/json > /dev/null && echo "✅ Chrome CDP active" || echo "⏳ Chrome starting..."
docker exec "$CONTAINER"   python3 /data/.openclaw/workspace/skills/virtual-desktop/browser_control.py status

# 11. Notify principal
VPS_IP=$(curl -s ifconfig.me 2>/dev/null || echo "YOUR_VPS_IP")
echo ""
echo "Virtual Desktop ready — https://${VPS_IP}:6901"
echo "Log in to all your platforms then reply DONE."

---

Initial Login — Once Per Platform

https://YOUR_VPS_IP:6901  —  login: kasm_user  /  password: your VNC_PW value

Open Chrome via noVNC and log in to all platforms. Sessions saved in Docker volume browser-profile — survive restarts — valid forever. Session expired → agent notifies via Telegram → principal reconnects in 2 min.

CAPTCHA — Autonomous Strategy

1. Auto-detection on every page load
   → reCAPTCHA v2/v3, hCaptcha, Cloudflare Turnstile

2. CapSolver API resolution (if CAPSOLVER_API_KEY set in .env)
   → Extracts sitekey → sends to API → receives token → injects → continues

3. Cloudflare Turnstile
   → CapSolver Chrome extension handles it in background → wait 60s → continues

4. Fallback
   → Screenshot → Telegram → principal opens noVNC → solves → agent continues

To enable: add CAPSOLVER_API_KEY=xxx to .env (~$0.001 per CAPTCHA)

---

Residential Proxy — If Site Blocks the VPS

# Option 1 — Browserbase (CAPTCHA + stealth + residential proxy built-in)
# Free tier: 1 concurrent session, 1h/month — browserbase.com
# Add to .env: BROWSERBASE_API_KEY=xxx
# Use: openclaw browser --browser-profile browserbase open <url>

# Option 2 — Custom proxy in browser_control.py
# Add to .env: PROXY_URL=http://user:pass@proxy:port
# In get_browser(): ctx = browser.new_context(proxy={"server": os.environ["PROXY_URL"]}, ...)

---

Claude Vision — Analyze Images and Pages

# Web page → auto screenshot + analysis
$BC analyze https://example.com "What does this page sell?"

# AI-generated image
$BC analyze https://site.com/image.png "Describe the visual elements"

# Existing screenshot
$BC analyze /workspace/screenshots/capture.png "Is there a form on this page?"

# Inside a JSON workflow
{ "action": "analyze", "value": "Identify all form fields on this page" }

---

Execution Protocol

BEFORE EVERY BROWSER ACTION:
  1. Log to AUDIT.md: "BEFORE [action] on [url]"
  2. Detect CAPTCHA → resolve automatically if present
  3. Execute
  4. Screenshot as proof
  5. Log to AUDIT.md: "OK/FAILED [action]"
  6. Telegram report if real-world consequences

NEVER:
  → Access platforms not authorized by the principal
  → Execute payments without explicit approval
  → Fail silently — always log
  → Retry more than 3 times without alerting principal

---

Error Recovery

CAPTCHA          → CapSolver auto → fallback noVNC
CLOUDFLARE       → switch to --browser-profile browserbase
SESSION EXPIRED  → Telegram → principal opens noVNC → reconnects
ELEMENT MISSING  → use analyze to understand the new layout
                 → log to .learnings/ERRORS.md with ref map
TIMEOUT          → check /workspace/logs/browser/YYYY-MM-DD.log

---

Security

This skill opens port 6901 (noVNC) on your VPS and stores authenticated browser sessions permanently. Before installing, understand what this means:

REQUIRED before running:
  1. Set a strong VNC_PW in .env — never use the default
  2. Firewall port 6901 to your IP only:
     → Hostinger: Panel → VPS → Firewall → restrict port 6901 to your IP
     → Or use SSH tunnel instead of opening the port publicly:
        ssh -L 6901:localhost:6901 user@YOUR_VPS_IP
        Then access via http://localhost:6901

  3. The agent will have autonomous access to whatever accounts
     you log into via noVNC — only log into accounts you trust
     the agent to access

  4. CAPSOLVER_API_KEY, BROWSERBASE_API_KEY, ANTHROPIC_API_KEY
     are optional — only add them if you trust those services
     and understand their costs
