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
