ScienceDirect Paper Detail Extraction

Extract complete metadata from a ScienceDirect article page.

Steps

Step 1: Navigate to article

Determine the article URL from $ARGUMENTS:

• If a PII is given (e.g. S0957417426005245): URL is {BASE_URL}/science/article/pii/{PII}
• If a full URL is given: use that URL directly
• If a DOI is given: URL is https://doi.org/{DOI} (will redirect to ScienceDirect)

Use navigate_page with initScript to prevent bot detection:

navigate_page({
  url: "{article_url}",
  initScript: "Object.defineProperty(navigator, 'webdriver', {get: () => undefined})"
})

If the article is already open in the current tab, you can skip this and go directly to Step 3.

Step 2: Check access

After navigation, verify:

• If the page shows "Are you a robot" or captcha: auto-click the Cloudflare Turnstile checkbox using the procedure below. If auto-click fails after 2 attempts, tell the user "请在浏览器中完成验证后告知我。"
• If the page URL no longer points to a ScienceDirect article, the user may need to log in. Tell the user: "页面被重定向，请在浏览器中完成登录或认证后告知我。" Then wait.

Cloudflare Turnstile auto-click procedure

When a captcha page is detected (title "请稍候…" or body contains "Are you a robot"):

1. Wait for the Turnstile iframe to load — use evaluate_script to poll for #captcha-box (up to 8s).
2. Take a snapshot — use take_snapshot to get the a11y tree. The checkbox is inside a cross-origin iframe but Chrome DevTools MCP can see it:

   Iframe "包含 Cloudflare 安全质询的小组件"
     checkbox "确认您是真人"   ← target uid
   

3. Click the checkbox — use click(uid) on the checkbox element.
4. Wait and verify — wait 3-5s, then check if document.contentType changed or the page URL changed (indicating success). If still on captcha, retry once or fall back to asking the user.

Step 3: Extract metadata

Use evaluate_script with built-in waiting. Do NOT use wait_for — it returns oversized snapshots on article pages.

async () => {
  // Wait for article content to load (up to 10s)
  for (let i = 0; i < 20; i++) {
    if (document.querySelector('.title-text') || document.querySelector('#abstracts')) break;
    await new Promise(r => setTimeout(r, 500));
  }

  const result = {};

  // Title
  result.title = document.querySelector('.title-text')?.textContent?.trim() || '';

  // Authors
  result.authors = [...document.querySelectorAll('.author-group .react-xocs-alternative-link')]
    .map(el => el.textContent.trim())
    .filter(Boolean);
  if (result.authors.length === 0) {
    result.authors = [...document.querySelectorAll('.author-group .button-link-text')]
      .( el..().(, ))
      .();
  }

  
  result. = [....()]
    .( el..()).();

  
   absDiv = .();
   (absDiv) {
     h2 = absDiv.();
     contentDiv = h2?.;
    result. = contentDiv?.?.() || ;
  }
   (!result.) {
    
     absSection = .();
     (absSection) {
       absParagraphs = absSection.();
      result. = [...absParagraphs].( p..()).();
    }
  }

  
   highlights = [....()];
   (highlights. > ) {
    result. = highlights.( li..());
  }

  
   kwSet =  ();
  .().( kwSet.(k..()));
  result. = [...kwSet];

  
   doiLink = .();
  result. = doiLink?. || ;

  
  result. = .()?.?.() || ;
   volText = .()?.?.() || ;
  result. = volText;

  
  result. = ...()?.[] || ;

  
  result. = .()?.?.() || ;

  
   pdfLink = .();
  result. = pdfLink?. || ;

  
   dateInfo = .();
  result. = dateInfo?.?.() || ;

  
  result. = .().;

  
  result. = [....()]
    .( h..()).();

   result;
}

Step 4: Present metadata

Format the output clearly:

## {title}

**Authors**: {authors}
**Journal**: {journal}, {volumeInfo}
**DOI**: {doi}
**Type**: {articleType}
**PII**: {pii}

### Abstract
{abstract}

### Highlights
- {highlight1}
- {highlight2}

### Keywords
{keywords}

### Article Structure
{sections}

**References**: {referenceCount} cited
**PDF**: {pdfUrl or "Not available"}

Key CSS Selectors

Element	Selector
Title	.title-text
Authors	.author-group .react-xocs-alternative-link
Affiliations	.affiliation dd
Abstract	.abstract.author (div after h2)
Highlights	.author-highlights li
Keywords	.keyword span
DOI link	a[href*="doi.org"]
Journal name	.publication-title-link
Volume/issue	.publication-volume .text-xs
PDF link	a[href*="pdfft"][class*="accessbar"]
References	.reference, .bibliography li
Section headings	.Body h2, .article-content h2

Notes

• PDF link format: {BASE_URL}/science/article/pii/{PII}/pdfft?md5={hash}&pid=1-s2.0-{PII}-main.pdf
• The PDF URL contains an md5 hash that must be extracted from the page; it cannot be constructed.
• Always include initScript on every navigate_page call to prevent bot detection.
• This skill uses 2 tool calls: navigate_page + evaluate_script.
