Unified Web Search Skill

Intelligently select the best search source, aggregate results, and return ranked answers with provenance.

Security

All search queries are validated and sanitized:

• Maximum query length: 500 characters
• Shell metacharacters are blocked to prevent command injection
• Local file searches are restricted to workspace directories only

Tool API

unified_web_search

Perform a unified search across multiple sources.

• Parameters:
  • query (string, required): The search query (alphanumeric, spaces, basic punctuation only)
  • sources (array of strings, optional): Array of sources to search. Defaults to ['tavily', 'web-search-plus', 'local']. Options: tavily, web-search-plus, browser, local.
  • max_results (integer, optional): Maximum number of results to return. Defaults to 5.

Usage:

# Search all sources
node skills/unified-web-search/index.js --query "my search term" --max_results 10

# Search specific sources
node skills/unified-web-search/index.js --query "AI developments" --sources '["tavily", "local"]' --max_results 10

# Search local files only
node skills/unified-web-search/index.js --query "meeting notes" --sources '["local"]'

Implementation

The skill aggregates results from multiple sources:

• Tavily: AI-optimized web search with relevance scoring (requires TAVILY_API_KEY)
• Web Search Plus: Broader web search coverage (placeholder for future integration)
• Browser: Targeted site scraping (placeholder for future integration)
• Local Files: Searches workspace directories for matching filenames

Results are scored and ranked by relevance, then returned with source attribution in JSON format.

Output Format

[
  {

    "title": "Article Title",
    "url": "https://example.com/article",
    "score": 0.95,
    "content": "Brief excerpt from the article..."
  },
  {
    "source": "local",
    "title": "/path/to/file.txt",
    "snippet": "Found query in filename: file.txt",
    "score": 0.5
  }
]

Environment Variables

• TAVILY_API_KEY: Required for Tavily search functionality. Get your key at https://app.tavily.com

Error Handling

• Returns error if query is missing or empty
• Returns error if query contains disallowed characters
• Gracefully handles API failures (continues with other sources)
• Warns if TAVILY_API_KEY is not set
