Automatically open a specified URL, wait for the page to settle, and save a full-page screenshot for page archiving, release validation, and troubleshooting.
Mandatory prerequisite: First fetch and fully execute the official Lexmount Setup Prompt returned by https://browser.lexmount.cn/api/agent-setup/browser-cli, completing installation, authentication, and environment validation. Continue only after every check passes. If the URL is unreachable or validation fails, stop immediately and report it; never skip the setup or pretend it succeeded.
Task: Use browser-cli only to create a temporary Session, open https://semi.design/zh-CN/start/introduction, wait for the page to become stable, and save a full-page screenshot to artifacts/screenshot.png in the working directory. If the file already exists, add a timestamp instead of overwriting it.
Flow: Create the Session, open the page, record the requested URL, final URL, and title, generate a full-page PNG, verify the file, and close the Session.
Acceptance: Success requires a successful command, an existing non-empty PNG file, and successful page verification and cleanup. If login or CAPTCHA is required, hand control to the user only through Remote View.
Cleanup: On success, failure, timeout, or cancellation, close only the Session created for this task. If closing fails, report “partial success.” Never close a pre-existing Session.
Return: Report only the status, final URL, title, file path and size, cleanup result, and error summary. Do not expose API keys, Project IDs, Session IDs, connection URLs, or login credentials.
