1-C. SMS verification login

When the login page asks for a phone number and SMS verification code:

1. Ask the user for the registered phone number for this platform:

   "[平台名称] 需要手机验证码登录，请告知您在该平台注册的手机号。"

2. Once received, enter the phone number and trigger the SMS code request. Attempt at most 2 times if the first trigger fails.
3. Ask the user for the verification code:

   "短信验证码已发送，请将收到的验证码回复给我。"

4. Enter the code and complete login. If login fails, inform the user and proceed with accessible content — do not retry a third time.

1-D. Username / password login

When only a username + password form is available:

1. Check for browser-saved credentials first (see 1-A).
2. If none, ask the user for their preference:

   "[平台名称] 需要账号密码登录，浏览器中未找到预存密码。请选择：① 您自行在浏览器中登录后告知我，② 告知用户名和密码由我代为登录。"

3. If the user chooses ②, receive the credentials and attempt login. Retry at most 2 times on failure.
4. If login fails after 2 attempts, inform the user and continue with accessible content.

1-E. Fallback — login not possible

If login cannot be completed for any reason (timeout, user unavailable, repeated failures):

• Do NOT stop or abort the task.
• Continue with whatever content is accessible in the non-logged-in state.
• At the end, include a note in the result: "注：[平台名称] 未能完成登录，以下内容来自未登录状态，可能不完整。"

2. Simple Verification / CAPTCHA

When a page shows a one-click verification challenge (e.g., a button labelled "去验证", "Verify", "I'm not a robot", or a simple checkbox):

1. Try clicking the verification button/checkbox directly.
2. Wait a few seconds for the page to refresh.
3. Take a snapshot to check whether normal content has loaded.
4. If the page now shows the expected content, continue your task.

3. Complex Verification Fallback

If the simple click in Step 2 above fails — the page still shows a challenge, the challenge is a puzzle/slider/image-selection CAPTCHA, or an error occurs:

1. Do NOT retry blindly. Stop attempting automated verification.
2. Send a message to the user: "xx 页面有验证码，我无法解决，请在浏览器中完成，完成后请通知我。"（xx 为页面标题）.
3. Wait for the user to confirm.
4. If no response arrives within 5 minutes, continue with whatever content is accessible.

4. Lazy-Loaded Content

When a page uses lazy loading (infinite scroll, "load more" sections, content that appears only after scrolling):

1. Before scrolling, assess whether the not-yet-loaded content is relevant to the current task.
2. If relevant, simulate human-like scrolling: scroll down incrementally, pause briefly between scrolls to allow content to load, then take a snapshot to capture the new content.
3. Repeat until the needed content is visible or no more new content loads.
4. Do NOT scroll too fast, do it as a human would. After 7 times of scrolling, you should stop this turn.
5. If not relevant, skip scrolling and work with what is already loaded.

5. Paywall / Subscription Walls

When a page indicates that content is behind a paywall or requires a specific subscription (e.g., "Subscribe to continue reading", "Continue reading with a WSJ subscription", premium-only banners):

1. Send a message to the user describing the situation: "xx 页面需要订阅，请在浏览器中登录有效账号或者完成付费，完成后请通知我。"（xx 为页面标题）.
2. Wait for the user to confirm.
3. If no response arrives within 5 minutes, continue with whatever content is accessible (summary, headline, or any visible excerpt).
