# AlphaXiv Paper Lookup Lookup paper: $ARGUMENTS > Quick single-paper reader with tiered source fallback (overview → full markdown → LaTeX source). Powered by [AlphaXiv](https://alphaxiv.org). ## Role & Positioning This skill is the **quick single-paper reader** that returns LLM-optimized summaries: | Skill | Source | Best for | |-------|--------|----------| | `/arxiv` | arXiv API | Batch search, PDF download, metadata | | `/deepxiv` | DeepXiv SDK | Progressive section-level reading | | `/semantic-scholar` | S2 API | Published venue metadata, citation counts | | **`/alphaxiv`** | **alphaxiv.org** | **Instant LLM-optimized summary of one paper, with LaTeX source fallback** | **Do NOT use this skill for** topic discovery, broad literature search, or multi-paper surveys — use `/research-lit` or `/arxiv` instead. ## Constants - **OVERVIEW_URL** = `https://alphaxiv.org/overview/{PAPER_ID}.md` - **ABS_URL** = `https://alphaxiv.org/abs/{PAPER_ID}.md` - **ARXIV_SRC_URL** = `https://arxiv.org/src/{PAPER_ID}` - **ALPHAXIV_UA** = `Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 Safari/537.36` — any modern browser UA works; update the version numbers if AlphaXiv starts blocking this value again > Overrides (append to arguments): > - `/alphaxiv 2401.12345` — quick overview > - `/alphaxiv "https://arxiv.org/abs/2401.12345"` — auto-extract ID > - `/alphaxiv 2401.12345 - depth: src` — force LaTeX source inspection > - `/alphaxiv 2401.12345 - depth: abs` — force full markdown ## Workflow ### Step 1: Parse Arguments & Extract Paper ID Parse `$ARGUMENTS` to extract a bare arXiv paper ID. Accept these input formats: - `https://arxiv.org/abs/2401.12345` or `https://arxiv.org/abs/2401.12345v2` - `https://arxiv.org/pdf/2401.12345` - `https://alphaxiv.org/overview/2401.12345` - `https://alphaxiv.org/abs/2401.12345` - `2401.12345` or `2401.12345v2` Strip version suffixes (`v1`, `v2`, ...) for API calls. Store as `PAPER_ID`. Parse optional directives: - **`- depth: overview|abs|src`**: force a specific tier instead of cascading ### Step 2: Fetch AlphaXiv Overview (Tier 1 — Fastest) Use `curl` with `{ALPHAXIV_UA}` to fetch the AlphaXiv overview. AlphaXiv may return 403 for non-browser User-Agents; setting a standard browser UA reduces false positives from bot-detection: ```bash curl -sL --max-time 15 -A "{ALPHAXIV_UA}" "https://alphaxiv.org/overview/{PAPER_ID}.md" ``` This returns a **structured, LLM-optimized report** designed for machine consumption. Use this as the default and preferred source. If the overview answers the user's question, **stop here**. Do not fetch deeper tiers unnecessarily. If the request fails (HTTP 4xx — 403 bot-block or 404 not-yet-processed) or returns empty content, proceed to Step 3. ### Step 3: Fetch Full AlphaXiv Markdown (Tier 2 — More Detail) Use `curl` with `{ALPHAXIV_UA}` to fetch the full paper markdown: ```bash curl -sL --max-time 15 -A "{ALPHAXIV_UA}" "http
