2. Navigate to

   <URL>

   .
3. Take a screenshot of the loaded page.

How the skill reports

The skill runs the Python script and captures its stdout as a JSON payload. OpenClaw parses the JSON and sends a message back:

✅ Screenshot saved: /home/main/clawd/diffusion_pdfs/screenshot.png

If the script prints an error, the skill forwards the error text.

Installation notes

1. Make sure

   chromedriver

   is in

   /usr/local/bin/chromedriver

   or set

   CHROMEDRIVER_PATH

   .
2. Make sure

   google-chrome

   (or

   chromium

   ) is in

   /usr/bin/google-chrome

   or set

   CHROME_BIN

   .
3. Install Python dependencies:

   pip install selenium

   (inside the virtual env you use for the skill).

pip install selenium

---

Logging & timeouts

The script uses a 5‑second static wait after navigation; replace with Selenium's

WebDriverWait

for dynamic waits.

If you encounter timeouts, adjust the

time.sleep(5)

value or use

WebDriverWait(driver, 20).until(...)

.

Feel free to tweak the script to fit your environment (proxy, authentication, etc.).
