## What it does

The skill queries the OpenAlex catalog using `scripts/openalex_cli.py`. The agent never runs manual `curl` commands. Every request goes through the bundled CLI to handle retries and rate limits automatically. Supported entities include works, author profiles, and research institutions.

Running the tool requires `uv` on the system PATH and a `.env` file in the home directory. The workflow enforces resolving entity names to OpenAlex IDs first before filtering. Filtering directly by text names is disallowed. Overview queries should use `--per-page 5–10` and `--select` to avoid swamping the agent context with massive payloads.

Queries can run keyless, but they share a tight $0.10 daily budget per IP address at 10 requests per second. Adding a free `OPENALEX_API_KEY` raises the limit to 30 requests per second and a $1 daily quota. The key is mandatory if you want to pull full-text articles directly from `content.openalex.org` using `download-pdf`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill literature-search-openalex -a claude-code
```
```bash
npx skills add google-deepmind/science-skills --skill literature_search_openalex -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill literature_search_openalex -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill literature_search_openalex -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install google-deepmind/science-skills literature_search_openalex
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill literature_search_openalex -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/google-deepmind/science-skills --path skills/literature_search_openalex
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill literature_search_openalex -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/google-deepmind/science-skills/tree/HEAD/skills/literature_search_openalex/SKILL.md

## When to use it
- Search academic papers and author profiles in the OpenAlex database
- Resolve DOIs to retrieve complete publication metadata
- Download open-access paper PDFs via `download-pdf`
- Aggregate citation counts and h-index metrics for researchers
- Group institutional research output by publication year and field

## Example prompts
- Find the top ten cited papers by Geoffrey Hinton using OpenAlex and list their titles and citation counts.
- Resolve DOI 10.1038/s41586-021-03819-2 with the OpenAlex skill and download the open-access PDF.
- Check my current OpenAlex daily credit status and rate limit with the rate-limit command.

# OpenAlex Skill

## Prerequisites

1.  **`uv`**: Read the `uv` skill and follow its Setup instructions to ensure
    `uv` is installed and on PATH.
2.  **User Notification**: If .licenses/literature_search_openalex_LICENSE.txt
    does not already exist in the workspace root directory then (1) prominently
    notify the user to check the terms at https://help.openalex.org/ and to
    always check the license of the papers retrieved by the skill for any
    restrictions, then (2) create the file recording the notification text and
    timestamp.
3.  **`.env` file**: Make sure the `.env` file exists in your home directory.
    Create one if it does not exist.
4.  **`OPENALEX_API_KEY`** (optional but recommended): The skill works without a
    key, but keyless requests share a $0.10/day budget per IP address. A free
    key has its own $1/day budget and higher rate limits, and is required to
    download full text from content.openalex.org (`download-pdf`). Adding
    `mailto` (the former "polite pool") no longer raises limits. You can obtain
    a free key at OpenAlex.org → account settings. Whenever checking for or
    requesting this key, you **MUST** use the safe credentials protocol in the
    `credentials` skill, without blocking keyless execution if it is unset.

## Core Rules

1.  **List Sources.** If this skill is used, ensure this is mentioned in the
    output AND list the URLs of all papers that were used in producing the
    output.
2.  **Resolve before filter.** NEVER filter by name. Always `resolve` a name to
    an ID first, then use that ID in `--filter`.
3.  **Use the CLI only.** Never call the API via `curl`/`urllib`. The CLI
    handles retries and rate limiting.
