name: cnki-search description: Search CNKI (中国知网) for papers by keyword. Use when the user wants to find academic papers on a topic. argument-hint: "[search keywords]"

CNKI Basic Search

Search CNKI for papers using keyword(s). Returns result count and structured result list (titles, URLs, authors, journal, date) in a single call.

Arguments

$ARGUMENTS contains the search keyword(s) in Chinese or English.

Steps

1. Navigate

Use mcp__chrome-devtools__navigate_page → https://kns.cnki.net/kns8s/search

2. Search + extract results (single evaluate_script, NO wait_for)

Replace YOUR_KEYWORDS with actual search terms:

async () => {
  const query = "YOUR_KEYWORDS";

  // Wait for search input (replaces wait_for)
  await new Promise((r, j) => {
    let n = 0;
    const c = () => { if (document.querySelector('input.search-input')) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); };
    c();
  });

  // Check captcha (only if visible on screen, not hidden SDK at top:-1000000)
  const outer = document.querySelector('#tcaptcha_transform_dy');
  if (outer && outer.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  // Fill and submit (verified selectors: input.search-input, input.search-btn)
  const input = document.querySelector('input.search-input');
  input.value = query;
  input.dispatchEvent(new Event('input', { bubbles: true }));
  document.querySelector('input.search-btn')?.click();

  // Wait for results
  await new Promise((r, j) => {
    let n = 0;
    const c = () => { if (document.body.innerText.includes('条结果')) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); };
    c();
  });

  // Check captcha again
  const outer2 = document.querySelector('#tcaptcha_transform_dy');
  if (outer2 && outer2.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  // Extract current page results (merged parse-results)
  const rows = document.querySelectorAll('.result-table-list tbody tr');
  const checkboxes = document.querySelectorAll('.result-table-list tbody input.cbItem');
  const results = Array.from(rows).map((row, i) => {
    const titleLink = row.querySelector('td.name a.fz14');
    const authors = Array.from(row.querySelectorAll('td.author a.KnowledgeNetLink') || []).map(a => a.innerText?.trim());
    const journal = row.querySelector('td.source a')?.innerText?.trim() || '';
    const date = row.querySelector('td.date')?.innerText?.trim() || '';
    const citations = row.querySelector('td.quote')?.innerText?.trim() || '';
    const downloads = row.querySelector('td.download')?.innerText?.trim() || '';
    return {
      n: i + 1,
      title: titleLink?.innerText?.trim() || '',
      href: titleLink?.href || '',
      exportId: checkboxes[i]?.value || '',
      authors: authors.join('; '),
      journal,
      date,
      citations,
      downloads
    };
  });

  return {
    query,
    total: document.querySelector('.pagerTitleCell')?.innerText?.match(/([\d,]+)/)?.[1] || '0',
    page: document.querySelector('.countPageMark')?.innerText || '1/1',
    results
  };
}

3. Report

Present results as a numbered list:

Searched CNKI for "$ARGUMENTS": found {total} results (page {page}).

1. {title}
   Authors: {authors} | Journal: {journal} | Date: {date}
   Citations: {citations} | Downloads: {downloads}

2. ...

4. Follow-up: navigate to a paper

When the user wants to open or download a specific paper, use navigate_page with the result's href URL directly — do NOT click the link (clicking opens a new tab and wastes 3 extra tool calls for tab management).

Captcha detection

Check #tcaptcha_transform_dy element's getBoundingClientRect().top >= 0. Tencent captcha SDK preloads DOM at top: -1000000px (off-screen, not active). Only return error: 'captcha' when top >= 0 (actually visible to user).

Verified selectors

Element	Selector	Notes
Search input	input.search-input	id=txt_search, placeholder "中文文献、外文文献"
Search button	input.search-btn	type="button"
Result count	.pagerTitleCell	text "共找到 X 条结果"
Page indicator	.countPageMark	text "1/300"
Result rows	.result-table-list tbody tr	Each row = one paper
Title link	td.name a.fz14	Paper title with href
Authors	td.author a.KnowledgeNetLink	Author name links
Journal	td.source a	Journal/source link
Date	td.date	Publication date text
Citations	td.quote	Citation count
Downloads	td.download	Download count

Batch export to Zotero

When user wants to save results to Zotero, use batch export directly from the results page — do NOT navigate to each detail page. The exportId in results equals the detail page's #export-id. Call cnki-export skill with batch mode (Step 1B). See cnki-export SKILL.md for details.

Tool calls: 2 (navigate + evaluate_script)
