# alphaxiv

Look up one arXiv paper and ask questions about it. The skill moves from an overview to full Markdown and LaTeX source when more detail is needed.

## What it does

Give the skill an arXiv ID or paper URL. It extracts the ID and fetches an AlphaXiv overview first. If that fails or does not answer the question, it tries the full Markdown text, then the LaTeX source. You can select `overview`, `abs`, or `src` as the depth.

For source-level questions, the skill downloads an archive to a temporary directory and inspects relevant `.tex` files selectively. When `research-wiki/` is present in the project, it also runs `research_wiki.py` to add the paper after answering. This is for reading a known paper, not discovering a topic or surveying multiple papers.

```

2. **Manually: put the files in place**
- File: `.cursor/skills/alphaxiv/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wanshuiyin/Auto-claude-code-research-in-sleep alphaxiv
```

2. **Manually: put the files in place**
- File: `.github/skills/alphaxiv/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill alphaxiv -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep --path skills/alphaxiv
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/alphaxiv/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill alphaxiv -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep/tree/HEAD/skills/alphaxiv/SKILL.md

## When to use it
- get an overview from an arXiv ID
- find experimental details in a paper's full text
- inspect equations or appendices in LaTeX source
- add a paper to `research-wiki/`

## Example prompts
- Explain the main idea of the paper with arXiv ID `2401.12345`.
- Summarize this paper: `https://arxiv.org/abs/2401.12345`.
- Check the proof in paper `2401.12345` using its LaTeX source.

# AlphaXiv Paper Lookup

Lookup paper: $ARGUMENTS

> Quick single-paper reader with tiered source fallback (overview → full markdown → LaTeX source). Powered by [AlphaXiv](https://www.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`** | **www.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://www.alphaxiv.org/overview/{PAPER_ID}.md`
- **ABS_URL** = `https://www.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` or `https://www.alphaxiv.org/overview/2401.12345`
- `https://alphaxiv.org/abs/2401.12345` or `https://www.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://www.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.
