SYSTEM DOCUMENTATION & REQUIREMENTS

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.

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 a bare arXiv ID, arXiv URL, or AlphaXiv URL and the skill fetches the AlphaXiv overview, an LLM-optimized structured summary. It only escalates to the full markdown or LaTeX source if the overview does not answer your question.

What is the difference between AlphaXiv overview and full markdown tiers?

The overview tier returns a concise structured report designed for machine consumption and is the fastest default. The full markdown tier provides the complete paper body, used when you need methodology details, experimental results, or specific sections.

Can I force the skill to read the arXiv LaTeX source directly?

Yes, append the directive '- depth: src' to force LaTeX source inspection, or '- depth: abs' for full markdown and '- depth: overview' for the summary tier. Without a directive, the skill cascades tiers automatically.

Does this skill parse PDF files of papers?

No, the skill reads structured markdown from AlphaXiv and LaTeX source from arXiv, not raw PDFs. If you need PDF-specific content, it will report that PDF parsing is outside its standalone scope.

What happens when arXiv rate-limits the source download?

If arXiv returns HTTP 429 during source download, the skill waits 5 seconds and retries once. If the request is still blocked, it reports the error clearly instead of failing silently.
