What problem does it solve? Getting a quick, accurate explanation of a single arXiv paper usually means downloading and skimming a full PDF. This Skill retrieves LLM-optimized paper summaries from AlphaXiv first, escalating to deeper sources only when needed, so you get answers fast without a broad literature search. ## Core Features & Use Cases - Tiered source fallback: Cascades from AlphaXiv overview (fastest) to full AlphaXiv markdown to raw arXiv LaTeX source, stopping as soon as the question is answered. - Flexible input parsing: Accepts bare arXiv IDs, arXiv abs/pdf URLs, and AlphaXiv URLs, stripping version suffixes automatically. - Selective source inspection: At the LaTeX tier, reads only the .tex files relevant to the question rather than the entire source tree. - Use Case: A user pastes an arXiv URL 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 Use the alphaxiv skill to explain arXiv paper 2401.12345 and summarize its main contributions.
