# AlphaXiv Paper Lookup Skill

This skill enables looking up academic papers from arxiv.org through alphaxiv.org's AI-generated summaries.

**Key Capabilities:**
- Accepts arxiv URLs, paper IDs, or alphaxiv links as input
- Extracts the paper identifier and fetches structured overviews
- Provides machine-readable markdown reports optimized for analysis

**Workflow:**
1. Parse the paper ID from user input (handles various formats like `2401.12345` or full URLs)
2. Retrieve the intermediate report via `https://alphaxiv.org/overview/{PAPER_ID}.md`
3. If needed, fetch full paper text from `https://alphaxiv.org/abs/{PAPER_ID}.md` as fallback

**When Applicable:**
Use when users share paper links, request explanations of research, or ask for summaries of academic work.

**Important Notes:**
- No authentication required
- 404 responses indicate reports haven't been generated yet
- The structured report is typically sufficient; full text is a fallback option
