## What it does

The skill implements a layered reading pipeline for research papers: start with a brief summary and read specific sections as needed. Full papers are loaded only when essential. By default, searches return 10 results. Passing an arXiv ID without flags defaults to the brief summary mode.

Under the hood, it resolves the `deepxiv_fetch.py` adapter from `.aris` or falls back to direct `deepxiv` CLI calls. Running this workflow requires `pip install deepxiv-sdk`. On the initial run, the CLI registers a free token into `~/.env`. Missing this Python package breaks command execution.

## Install

### Claude Code (native platform)

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

2. **Manually: put the files in place**
- File: `~/.claude/skills/deepxiv/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/deepxiv/

### Codex

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

2. **Manually: put the files in place**
- File: `.agents/skills/deepxiv/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/deepxiv/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 deepxiv
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/deepxiv/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 deepxiv -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/deepxiv/SKILL.md

## When to use it
- search academic papers with custom result limits
- inspect individual paper sections without fetching full text
- track trending papers over 7, 14, or 30 days
- retrieve Semantic Scholar metadata by paper ID

## Example prompts
- /deepxiv "agent memory" - max: 5
- /deepxiv "2409.05591" - section: Introduction
- /deepxiv "trending" - days: 14 - max: 10

# DeepXiv Paper Search & Progressive Reading

Search topic or paper ID: $ARGUMENTS

## Role & Positioning

DeepXiv is the **progressive-reading** literature source:

| 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 |

Use DeepXiv when you want to avoid loading full papers too early.

## Constants

- **DEEPXIV_FETCHER** — canonical name `deepxiv_fetch.py`, resolved per
  [`shared-references/integration-contract.md`](../shared-references/integration-contract.md) §2
  (Policy D1 — primary + fallback cascade). If unresolved (canonical
  chain exhausted), fall back to the raw `deepxiv` CLI (documented per
  command below).
- **MAX_RESULTS = 10** — Default number of results to return.

> Overrides (append to arguments):
> - `/deepxiv "agent memory" - max: 5` — top 5 results
> - `/deepxiv "2409.05591" - brief` — quick paper summary
> - `/deepxiv "2409.05591" - head` — metadata + section overview
> - `/deepxiv "2409.05591" - section: Introduction` — read one section only
> - `/deepxiv "trending" - days: 14 - max: 10` — trending papers
> - `/deepxiv "karpathy" - web` — DeepXiv web search
> - `/deepxiv "258001" - sc` — Semantic Scholar metadata by ID

## Setup

DeepXiv is optional. If the CLI is not installed, tell the user:

```bash
pip install deepxiv-sdk
```

On first use, `deepxiv` auto-registers a free token and stores it in `~/.env`.

## Workflow

### Step 1: Parse Arguments

Parse `$ARGUMENTS` for:

- **Query or ID**: a paper topic, arXiv ID, or Semantic Scholar ID
- **`- max: N`**: override `MAX_RESULTS`
- **`- brief`**: fetch paper brief
- **`- head`**: fetch metadata and section map
- **`- section: NAME`**: fetch one named section
- **`- trending`** or query `trending`: fetch trending papers
- **`- days: 7|14|30`**: trending time window
- **`- web`**: run DeepXiv web search
- **`- sc`**: fetch Semantic Scholar metadata by ID

If the main argument looks like an arXiv ID and no explicit mode is given, default to `- brief`.

### Step 2: Locate the Adapter

Resolve `$DEEPXIV_FETCHER` via the canonical strict-safe chain (see
[`shared-references/integration-contract.md`](../shared-references/integration-contract.md) §2).
Policy D1 cascade: the resolved adapter is preferred; if unresolved
(canonical chain exhausted), fall back to raw `deepxiv` CLI commands
documented in Step 3.

```bash
cd "$(git rev-parse --show-toplevel 2>/dev/null || pwd)" || exit 1
if [ -z "${ARIS_REPO:-}" ] && [ -f .aris/installed-skills.txt ]; then
````
