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 | $0.00033 | $0.01430 |
| Opus 5.5 | $0.00013 | $0.00572 |
| Sonnet 5.5 | $0.00007 | $0.00286 |
| Haiku 4.5 | $0.00003 | $0.00143 |
Grade A, and why
sd-advanced-search 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 today.
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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ScienceDirect Advanced Search
Perform a filtered search on ScienceDirect by constructing URL parameters directly.
URL Parameter Reference
Build the search URL as {BASE_URL}/search?{params}&show=25 using these parameters:
| Param | Field | Example |
|---|---|---|
qs |
All fields (keywords) | machine learning |
tak |
Title, abstract or keywords | neural network |
title |
Title only | transformer |
authors |
Author name(s) | Hinton |
pub |
Journal or book title | Nature |
date |
Year or year range | 2023 or 2020-2025 |
volume |
Volume number(s) | 5 or 7-11 |
issue |
Issue number(s) | 1 or 1-3 |
page |
Page number(s) | 55 or 1-9 |
docId |
ISSN or ISBN | 0957-4174 |
affiliations |
Author affiliation | MIT |
references |
Cited references | Smith 2020 |
Multiple parameters can be combined. For example:
{BASE_URL}/search?tak=deep+learning&authors=LeCun&date=2020-2025&show=25
Steps
Step 1: Parse user intent
From $ARGUMENTS, identify which fields the user wants to filter on. Map natural language to URL parameters:
- "by author X" →
authors=X - "in journal Y" →
pub=Y - "from 2020 to 2025" / "since 2020" →
date=2020-2025 - "about topic Z" →
tak=Zorqs=Z - "titled ..." →
title=...
Step 2: Navigate
Use navigate_page to the constructed URL. Always include initScript to prevent bot detection:
initScript: "Object.defineProperty(navigator, 'webdriver', {get: () => undefined})"
Step 3: Check access
- 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 URL no longer contains
sciencedirectorsearchafter navigation, the user may have been redirected to a login/authentication page. 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.

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.

sd-advanced-search is a skill published in the GitHub repository YuanyuanMa03/academic-research-skills (75 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 1,430 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-29.
