wanshuiyin/auto-claude-code-research-in-sleep

This one searches and analyzes academic papers across a surprising number of sources. It'll check your local PDFs, Zotero library, Obsidian notes, then hit arXiv, Semantic Scholar, and even newer APIs like DeepXiv and OpenAlex if you ask for them. The source prioritization is smart: it starts with what you already have before going to the web. You can override which sources it checks with a simple flag, and it'll optionally download arXiv PDFs for you. Most useful when you're starting a literature review or need to quickly understand what a paper says without reading 40 pages. The Zotero integration is especially nice since it pulls your existing highlights and annotations.

Constants

PAPER_LIBRARY — Local directory containing user's paper collection (PDFs). Check these paths in order:
1. papers/ in the current project directory
2. literature/ in the current project directory
3. Custom path specified by user in CLAUDE.md under ## Paper Library
MAX_LOCAL_PAPERS = 20 — Maximum number of local PDFs to scan (read first 3 pages each). If more are found, prioritize by filename relevance to the topic.
SOURCES = all — Which literature sources to search. Options: zotero, obsidian, local, web, semantic-scholar, deepxiv, exa, gemini, openalex, all. Full source table and selection rules: see ## Data Sources below.
ARXIV_DOWNLOAD = false — When true, download top 3-5 most relevant arXiv PDFs to PAPER_LIBRARY after search. When false (default), only fetch metadata (title, abstract, authors) via arXiv API — no files are downloaded.
ARXIV_MAX_DOWNLOAD = 5 — Maximum number of PDFs to download when ARXIV_DOWNLOAD = true.
