This repository is a collection of Claude Code skills and Python scripts that automate daily paper recommendation and note-taking for researchers. It fetches papers from HuggingFace Daily Papers, HuggingFace Trending, and arXiv API, scores them against user-defined keywords, enriches metadata (authors, affiliations, figures, method names), and generates a tiered daily recommendation markdown file (must-read, worth reading, skip). For must-read papers, it invokes a paper-reader skill that produces detailed structured notes with figures, formulas, tables, and concept wiki entries, all saved into an Obsidian vault. It also fetches GitHub Trending repositories and writes notes. The system includes a web viewer (FastAPI + vanilla JS) for browsing the vault content, with full-text search, wikilink resolution, and a Claude chat interface. The architecture is a three-step pipeline (fetch, review, notes) orchestrated by Claude Code skills, with Python scripts handling data fetching, scoring, enrichment, and file management. The codebase demonstrates solid engineering: async HTTP with fallback chains, robust HTML parsing, heuristic text extraction, and clean modular design. It is primarily an application (a set of tools) rather than a data research project, though it involves significant data processing.
