Step 1: Capture video URLs

{"tool": "web_browser", "action": "capture_video", "url": "<video_page_url>"}

This opens the page, waits for video to load, and returns all detected video URLs.

Step 2: Download

Pick the best URL from the result (prefer mp4/playaddr, avoid thumbnail/poster), then:

{"tool": "web_download", "url": "<best_video_url>", "path": "video.mp4", "use_browser_cookies": true}

path is just a filename — no ~/ or absolute paths.

Step 3: Send to user

{"tool": "send_file", "path": "<downloaded_file_path>"}

If login required

Use web_browser to screenshot the QR code and send to user:

{"tool": "web_browser", "action": "screenshot"}

Wait for user to scan, then retry step 1.

Rules

• Do NOT use exec/curl/wget/yt-dlp
• Always use use_browser_cookies: true in web_download
• If capture_video returns empty, the video may need login or is DRM-protected
