openclaw skills install @biohackerrrrrr/paper-fetcher
Or with the ClawHub CLI, for registry-managed skill folders outside a full OpenClaw workspace:
npx clawhub install paper-fetcher
What This Skill Does
Fetches academic papers from Sci-Hub by DOI and saves PDFs to a local research/papers/ directory with standardized filenames. Accepts DOIs with or without the https://doi.org/ prefix and supports batch fetching of multiple papers at once.
Automates the Sci-Hub navigation and file-saving steps that would otherwise require manual browser interaction for each paper.
When to use it
- Downloading a paywalled journal article by DOI
- Batch saving papers from a citation list
- Fetching papers referenced in a research protocol
- Archiving a PubMed reading list to disk
- Building a local PDF library for a literature review
Example Workflow
Here's how your AI assistant might use this skill in practice.
INPUT
User asks: Get paper: 10.1038/nature12345
AGENT
- 1Extracts DOI from the message
- 2Navigates to https://www.sci-hub.su/10.1038/nature12345
- 3Waits for page to load and locates the PDF download link
- 4Downloads the PDF
- 5Saves file to research/papers/paper_10.1038_nature12345.pdf
OUTPUT
Confirmation with file path: research/papers/paper_10.1038_nature12345.pdf
