Provides:

  • Tool selection guidance
  • Query formulation tips
  • When to use deep vs standard search
  • Prompting best practices
  • Example workflows

Tool Selection Guide

Use linkup_web_search when:

  • Finding information across multiple sources
  • Research and discovery
  • Need to see different perspectives

Use linkup_web_answer when:

  • Need a direct answer to a specific question
  • Want a quick summary from multiple sources
  • Time-sensitive queries

Use linkup_web_fetch when:

  • Reading documentation from a known URL
  • Following up on search results
  • Extracting content from specific articles

Best Practices

  1. Be specific with queries: "Microsoft 2024 Q4 revenue" beats "Microsoft revenue"
  2. Use deep mode strategically: Deep searches are thorough but slower
  3. Choose the right tool: search for discovery, answer for facts, fetch for known URLs
  4. Monitor usage: Check /linkup:balance to track credit consumption
