What it does

Gs Cited By is an agent skill from cookjohn/gs-skills. Find papers that cite a given Google Scholar paper. Tracks citation chains using data-cid (cluster ID). Use when user wants to see who cited a specific paper.

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Academic paper search and Citation management. The repository describes itself as: Google Scholar skills for Claude Code — search, citation tracking, full-text access, and Zotero export via Chrome DevTools MCP. The licence is MIT.

Workflow steps

Extract citing papers (evaluate_script)
Report

What it can do on your machine

Read from SKILL.md and the folder at commit df03c99. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- scholar.google.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gs Cited By loads about 935 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 219 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~43
When it runs · the whole SKILL.md, loaded when a task matches: ~935

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: gs-cited-by
description: Find papers that cite a given Google Scholar paper. Tracks citation chains using data-cid (cluster ID). Use when user wants to see who cited a specific paper.
argument-hint: [data-cid or paper title to look up]

Google Scholar — Cited By (Citation Tracking)

Find all papers that cite a given paper. Uses Google Scholar's cites parameter with the paper's cluster ID (data-cid).

Arguments

$ARGUMENTS can be:

A data-cid from a previous search result (e.g., TFS2GgoGiNUJ)
A paper title (will search first to find the data-cid)

Steps

Step 1: Resolve data-cid

If $ARGUMENTS is a data-cid (alphanumeric string, no spaces): use it directly.

If $ARGUMENTS is a title or description: first search to find the data-cid:

Use gs-search with the title as keywords
Match the target paper in results by title similarity
Extract its dataCid

Step 2: Navigate to "Cited by" page

Use mcp__chrome-devtools__navigate_page:

url: https://scholar.google.com/scholar?cites={DATA_CID}&hl=en&num=10

Replace {DATA_CID} with the resolved cluster ID.

Step 3: Extract citing papers (evaluate_script)

Same extraction script as gs-search:

javascript

async () => {
  for (let i = 0; i < 20; i++) {
    if (document.querySelector('#gs_res_ccl') || document.querySelector('#gs_captcha_ccl')) break;
    await new Promise(r => setTimeout(r, 500));
  }

  if (document.querySelector('#gs_captcha_ccl') || document.body.innerText.includes('unusual traffic')) {
    return { error: 'captcha', message: 'Google Scholar requires CAPTCHA verification. Please complete it in your browser, then tell me to continue.' };
  }

  const items = document.querySelectorAll('#gs_res_ccl .gs_r.gs_or.gs_scl');
  const results = Array.from(items).map((item, i) => {
    const titleEl = item.querySelector('.gs_rt a');
    const meta = item.querySelector('.gs_a')?.textContent || '';
    const parts = meta.split(' - ');
    const authors = parts[0]?.trim() || '';
    const journalYear = parts[1]?.trim() || '';
    const citedByEl = item.querySelector('.gs_fl a[href*="cites"]');

    return {
      n: i + 1,
      title: titleEl?.textContent?.trim() || item.querySelector('.gs_rt')?.textContent?.trim() || '',
      href: titleEl?.href || '',
      authors,
      journalYear,
      citedBy: citedByEl?.textContent?.match(/\d+/)?.[0] || '0',
      dataCid: item.getAttribute('data-cid') || '',
      fullTextUrl: (item.querySelector('.gs_ggs a') || item.querySelector('.gs_or_ggsm a'))?.href || '',
      snippet: item.querySelector('.gs_rs')?.textContent?.trim()?.substring(0, 200) || ''
    };
  });

  const totalText = document.querySelector('#gs_ab_md')?.textContent?.trim() || '';
  const currentUrl = window.location.href;
  return { total: totalText, resultCount: results.length, currentUrl, results };
}

Step 4: Report

Papers citing [{original paper title}] (data-cid: {DATA_CID}):
{total}

1. {title}
   Authors: {authors} | {journalYear}
   Cited by: {citedBy}
   Data-CID: {dataCid}

2. ...

Follow-up

See more citing papers: use gs-navigate-pages (pagination works on cited-by pages too)
Export citing papers: use gs-export with the data-cid(s)
Recursive citation tracking: use gs-cited-by on any of the citing papers

Notes

This skill uses 2-3 tool calls: optional search + navigate_page + evaluate_script
The cites parameter uses the cluster ID (data-cid), NOT a DOI or paper ID
Cited-by pages support the same pagination as regular search (start parameter)
Citation count on Google Scholar is typically higher than PubMed because it includes non-PubMed sources (books, theses, preprints, etc.)
