A research is searching around something.

This skill largely does what it says (download papers, convert, web-search, synthesize) but has a few red flags you should resolve before installing: - Confirm which LLM provider it will use: the code calls Anthropic/Claude endpoints and has a --anthropic-key flag, but the registry only lists OPENROUTER_API_KEY. Ask the author which key the tool needs and whether OpenRouter or Anthropic will be used. Do not provide unrelated credentials. - Review the code paths that send extracted PDF/text/web content to remote APIs (OpenRouter / Anthropic / Serper). If you plan to run on sensitive topics or internal URLs, be aware those contents will be transmitted externally. - The included web_fetcher supports proxy pools, stealth headers, and curl_cffi fingerprinting — useful for scraping but able to bypass rate-limits/blocks. If that worries you, run the tool in a sandbox, restrict networking, or remove/disable proxy features. - The SKILL.md tells you to pip-install packages and copy the script into /usr/local/bin. Prefer running inside a virtualenv or container instead of installing system-wide, and inspect the scripts' source before making them executable. If you cannot get clarification from the publisher, treat this skill as untrusted: run it in an isolated environment, avoid supplying extra credentials until clarified, and consider adding the missing ANTHROPIC_API_KEY to the declared metadata only after confirming its legitimate need.
