Cat_paper_search

Find academic papers and read them — searches real scholarly databases for prior work on a topic, then resolves and deep-reads the open-access PDF of any paper you pick. Use this skill WHENEVER the user wants to discover literature or read a study: "find recent papers on X", "what does the research say about Y", "find sources for my thesis on Z", "search for prior work on ...", or "summarise / read / extract the findings from this paper / this arXiv id / this DOI / this PDF". Trigger even when the tool isn't named. Results are real papers from public APIs (OpenAlex, Crossref, arXiv, Semantic Scholar, Europe PMC) and reading reports use only the actual extracted PDF text — nothing is fabricated.
