Overview

The Valyu community has built powerful skills that extend AI coding agents with specialized capabilities. These community-maintained integrations provide domain-specific search and research functionality.

​
Scientific Skills

Repository: yorkeccak/scientific-skills Natural language scientific literature search with semantic search over PubMed, arXiv, ChEMBL, DrugBank, bioRxiv, medRxiv, clinical trials, and more.

​
Why Scientific Skills Are Powerful

  • No API Parameter Parsing: Pass natural language queries directly - no complex search syntax required
  • Semantic Search: Understands meaning and context, not just keyword matching
  • Full-Text Access: Returns complete article content, not just abstracts
  • Image Links: Includes figures and images from papers
  • Comprehensive Coverage: Access to all scientific literature across multiple databases

​

​
Installation

Via skills.sh (Recommended) 
npx skills i yorkeccak/scientific-skills
Or browse individual skills at skills.sh - search for “yorkeccak” Example: skills.sh/yorkeccak/scientific-skills/biomedical-search Via Claude Plugin 
/plugin install yorkeccak/scientific-skills
Manual Installation 
# Clone the repository
cd ~/dev
git clone https://github.com/yorkeccak/scientific-skills.git

# Add as a local plugin
/plugin add ~/dev/scientific-skills

​
Setup

Get your API key from platform.valyu.ai with $10 free credits. First Use (Automatic) Just start using any skill - Claude will automatically detect that no API key is configured, ask for your key, save it, and run your search. Manual Setup (Optional) 
echo 'export VALYU_API_KEY="your-api-key-here"' >> ~/.zshrc
source ~/.zshrc

​
Usage Examples

Literature Review Search across all scientific literature: 
Search PubMed for CRISPR advances in 2024
Drug Discovery Find compounds and targets: 
Find kinase inhibitors for melanoma using drug discovery search
Clinical Research Find trials and patient outcomes: 
Search biomedical sources for checkpoint inhibitor combinations trials
Patent Research Search for prior art: 
Search patents for CRISPR delivery methods

​
Output Format

All skills return consistent JSON output: 
{
  "success": true,
  "type": "pubmed_search",
  "query": "your query",
  "result_count": 10,
  "results": [
    {
      "title": "Article Title",
      "url": "https://...",
      "content": "Full article text with figures...",
      "source": "pubmed",
      "relevance_score": 0.95,
      "images": ["https://example.com/figure1.jpg"]
    }
  ],
  "cost": 0.025
}

​
Processing Results

With jq 
# Get article titles
jq -r '.results[].title'

# Get URLs
jq -r '.results[].url'

# Extract content
jq -r '.results[].content'

# Filter by relevance score
jq '.results[] | select(.relevance_score > 0.9)'
