Paper Downloader Skill

Purpose

Download paper PDFs and clone associated source code repositories. This is the second step in the paper reproduction pipeline, following paper-finder.

When to Use

• After running paper-finder to get paper_info.json
• User asks to "download", "get", or "fetch" a paper's PDF
• User asks to "clone" or "get the code" for a paper
• User asks to "reproduce" a paper (run paper-finder first, then this)

How to Use

Step 1: Ensure paper_info.json exists

Run paper-finder first if needed:

python skills/paper-finder/scripts/search_paper.py "<query>" --output workspace/paper_info.json

Step 2: Run the Download Script

python skills/paper-downloader/download_paper.py workspace/paper_info.json

Options:

• --allow-scihub — Enable Sci-Hub as fallback PDF source
• --clone-depth 0 — Full git clone (default: shallow clone)
• --skip-code — Only download PDF
• --skip-pdf — Only clone code
• -o <dir> — Custom output directory

Step 3: Read the Results

Check workspace/<paper-slug>/download_report.json for:

• PDF download status and path
• Code clone status and path
• Step-by-step log

Step 4: Report to User

Tell the user:

• Where the PDF was saved
• Where the code was cloned
• Which dependency files were found in the repo

Dependencies

• Python 3.10+
• requests library
• git command-line tool
