## What it does

The skill retrieves scholarly works directly from OpenAlex. It gathers paper titles, author lists, citation counts, abstracts, research concepts, and open-access PDF links using two local bash scripts: `search.sh` and `paper.sh`.

Keyword searches handled by `search.sh` support pagination, custom output limits up to 200 items, and sorting by relevance, citation count, or publication date. To inspect an individual paper, `paper.sh` takes a DOI URL or an OpenAlex identifier, returning metadata alongside related work identifiers for citation graph exploration.

No external API token or account is necessary because OpenAlex provides free public access. Running the commands depends entirely on bash execution inside the agent workspace.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ykdojo/paper-search --skill paper-search -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ykdojo/paper-search --skill paper-search -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ykdojo/paper-search --skill paper-search -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ykdojo/paper-search paper-search
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ykdojo/paper-search --skill paper-search -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ykdojo/paper-search --path skills/paper-search
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ykdojo/paper-search --skill paper-search -a opencode
```

### Claude.ai

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

name: paper-search
description: Search for academic papers by keyword, or look up a specific paper by DOI or OpenAlex ID. Powered by OpenAlex (250M+ works, free, no API key).

Search for academic papers and get details including title, authors, citation count, DOI, abstract, and open access links.

Steps:
1. Find the scripts directory: `find ~/.claude -name "search.sh" -path "*/paper-search/*" 2>/dev/null | sort -V | tail -1`
   - This finds the script whether installed via plugin or manual setup
   - The `paper.sh` script is in the same directory
2. To search for papers by keyword:
   ```
   <scripts-dir>/search.sh "your search query" [limit] [sort] [page]
   ```
   - `limit`: number of results per page (default: 10, max: 200)
   - `sort`: `relevance` (default), `cites`, or `date`
   - `page`: page number for pagination (default: 1)
3. To look up a specific paper by DOI or OpenAlex ID:
   ```
   <scripts-dir>/paper.sh <DOI_URL or OpenAlex_ID>
   ```
   - Accepts full DOI URLs like `https://doi.org/10.3390/brainsci8020020`
   - Or OpenAlex IDs like `W2789811475`
   - Returns full details: authors, abstract, concepts, open access PDF link, related works

Tips:
- Use `relevance` sort (default) for topical searches. Use `cites` when you want landmark papers.
- Be specific with queries — "bilingual cognitive advantages executive function" beats "bilingualism brain".
- Use `paper.sh` to get the full abstract when search results show "Abstract: N/A".
- The `related_works` IDs from `paper.sh` can be fed back into `paper.sh` to explore the citation graph.
- When the user asks for scientific backing: search broadly first, pick the most relevant/cited papers, then use `paper.sh` for full details and cite as (Author, Year, Journal).
