# literature-search

Searches PubMed, arXiv, bioRxiv and medRxiv at once from a plain-language query. Useful when you need a literature review, not a keyword hit list.

## What it does

The skill sends your query to Valyu's semantic search and returns hits from four databases in one response. No parameters to assemble: you type the phrase as you'd say it, say about mechanisms of cellular senescence. Each result carries a title, URL, the full article text and links to figures, plus a relevance score and the source it came from.

Under the hood there are two files: a bash wrapper `scripts/search` and a Node.js CLI `search.mjs`. No external dependencies, requests go through the built-in `fetch()`. You need Node.js 18 or newer and a Valyu API key, handed out at platform.valyu.ai along with free credits. Without a key the first run returns `"setup_required": true` and the skill asks for it, then stores it via `scripts/search setup <api-key>`.

The script path in the docs is relative, so before running anything you locate it with `find` under the plugin cache directory and use the full path. Keep that in mind: the example commands fail without the substitution. Output is JSON, and `jq` handles it well — pull just the titles, or filter down to source `arxiv`.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add yorkeccak/scientific-skills --skill literature-search -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add yorkeccak/scientific-skills --skill literature-search -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install yorkeccak/scientific-skills literature-search
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/yorkeccak/scientific-skills --path skills/literature-search
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yorkeccak/scientific-skills --skill literature-search -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/yorkeccak/scientific-skills/tree/HEAD/skills/literature-search/SKILL.md

## When to use it
- build a literature review on one topic across four databases
- catch fresh preprints before they reach journals
- pull the full text of a paper instead of the abstract
- merge biomedical and physics work into a single list
- filter results down to one source with jq

## Example prompts
- Find papers on CRISPR gene editing advances, 15 results
- Search the literature for mechanisms of cellular senescence, around 100 papers
- Collect preprints on foundation models for protein folding, 30 of them

# Literature Search

Search across all major scientific literature databases (PubMed, arXiv, bioRxiv, medRxiv) simultaneously using natural language queries powered by Valyu's semantic search API.

## Why This Skill is Powerful

- **No API Parameter Parsing**: Just pass natural language queries directly - no need to construct complex search parameters
- **Semantic Search**: Understands the meaning of your query, not just keyword matching
- **Full-Text Access**: Returns complete article content, not just abstracts
- **Image Links**: Includes figures and images from papers
- **Comprehensive Coverage**: Search across PubMed, arXiv, bioRxiv, and medRxiv simultaneously
- **Unified Results**: Get results from all sources in a single query

## Requirements

1. Node.js 18+ (uses built-in fetch)
2. Valyu API key from https://platform.valyu.ai ($10 free credits)

## CRITICAL: Script Path Resolution

The `scripts/search` commands in this documentation are relative to this skill's installation directory.

Before running any command, locate the script using:

```bash
LITERATURE_SCRIPT=$(find ~/.claude/plugins/cache -name "search" -path "*/literature-search/*/scripts/*" -type f 2>/dev/null | head -1)
```

Then use the full path for all commands:
```bash
$LITERATURE_SCRIPT "CRISPR gene editing advances" 15
```

## API Key Setup Flow

When you run a search and receive `"setup_required": true`, follow this flow:

1. **Ask the user for their API key:**
   "To search scientific literature, I need your Valyu API key. Get one free ($10 credits) at https://platform.valyu.ai"

2. **Once the user provides the key, run:**
   ```bash
   scripts/search setup <api-key>
   ```

3. **Retry the original search.**

## When to Use This Skill

- Comprehensive literature reviews across all domains
- Finding all relevant research on a topic
- Cross-domain scientific discovery
- Combining biomedical, physics, and preprint literature
- Emerging research across disciplines
## Output Format

```json
{
  "success": true,
  "type": "literature_search",
  "query": "CRISPR gene editing advances",
  "result_count": 15,
  "results": [
    {
      "title": "Article Title",
      "url": "https://...",
