When to use

• Reading and summarising an academic paper.

Workflow

1. Determine whether the input is a PDF file or an arXiv URL.
2. If the input is a PDF file:
   1. Use pdftoppm to convert the PDF into PNG images. Save them under .cache/{paper name}/ as [1,2,3,...].png.
   2. Read the converted images.
   3. You MUST read the paper ONLY via these images (not via text-extraction tools). Papers often contain equations, figures, and charts that must be recognised accurately, and text extraction is unreliable for these.
3. If the input is an arXiv URL (e.g. https://www.arxiv.org/abs/2601.07372):
   1. Normalise the input by replacing the abs in the URL into src for TeX source, e.g.: https://www.arxiv.org/src/2601.07372.
   2. Download the source as a local .tar.gz archive and store it under .cache/downloads/{paper name}/.
   3. Unpack the archive into .cache/{paper name}/.
   4. Locate the entry point (e.g. main.tex) and read all relevant contents, including referenced figures.
4. Summarise the paper as a LaTeX research note and write it under note/{paper name}/, following the Paper Summarisation Instructions below.
5. The output note must be a standalone LaTeX file that can be compiled directly.
