SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Reading a full research paper to answer one question is slow and token-expensive. This Skill retrieves a structured, LLM-optimized summary of a single arXiv paper from AlphaXiv, escalating to full markdown or raw LaTeX source only when deeper detail is needed. ## Core Features & Use Cases - Tiered Source Fallback: Cascades from AlphaXiv overview to full markdown to arXiv LaTeX source, stopping as soon as the question is answered. - Flexible ID Parsing: Accepts bare arXiv IDs, arXiv abs/pdf URLs, or AlphaXiv URLs, stripping version suffixes automatically. - Research Wiki Ingest: Optionally logs the paper summary into a local research-wiki for long-term knowledge management. - Use Case: A user pastes an arXiv link and asks "what is the main contribution of this paper?" The Skill fetches the AlphaXiv overview and returns a concise summary with key points in seconds. ## Quick Start Ask the assistant to summarize arXiv paper 2401.12345 using the alphaxiv skill.

Frequently Asked Questions about alphaxiv

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I get a quick summary of an arXiv paper?▼

Provide the arXiv ID or URL to the alphaxiv skill, which fetches a structured LLM-optimized overview from alphaxiv.org. The overview contains the paper's thesis and key points, answering most questions without reading the full text.

What is the difference between AlphaXiv, arXiv API, and DeepXiv for reading papers?▼

AlphaXiv provides instant LLM-optimized summaries of one paper, the arXiv API handles batch search and PDF download, and DeepXiv supports progressive section-level reading. Use AlphaXiv for fast single-paper understanding, not broad literature search.

Can I read a paper's equations or appendix without downloading the PDF?▼

Yes, the skill downloads the arXiv LaTeX source archive and selectively reads only the relevant .tex files, such as appendices or sections with equations. It does not parse PDFs directly.

Why does AlphaXiv return a 403 error when fetching a paper?▼

AlphaXiv blocks non-browser user agents with 403 responses. The skill sends a standard browser User-Agent header with curl to avoid bot detection; if the paper is not yet processed, it falls back to deeper source tiers.

When should I not use AlphaXiv for paper lookup?▼

Do not use it for topic discovery, broad literature search, or multi-paper surveys; use a literature search skill instead. It is designed for quick understanding of one specific paper identified by an arXiv ID.
