Usage

The skill triggers on any message that contains Chrome, browser, Selenium, screenshot, or open.

selenium-browser <URL> [--headless] [--proxy=<url>]

Command flow

1. Launch Chrome (or Chromium) under Selenium.
2. Navigate to <URL>.
3. Take a screenshot of the loaded page.
4. Save the image in /home/main/clawd/diffusion_pdfs/ and report the path back to the chat.
5. If anything fails, send an error message.

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.).
