Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.01010 |
| Opus 5 | $0.00019 | $0.00505 |
| Sonnet 5 | $0.00008 | $0.00202 |
| Haiku 4.5 | $0.00004 | $0.00101 |
Grade A, and why
gs-cited-by scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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-cidfrom 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-searchwith 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:
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 };
}
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gs-cited-by is a skill published in the GitHub repository cookjohn/gs-skills (506 stars, last pushed 6mo ago), licensed MIT. It adds 38 tokens to every session and 1,010 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
