Web search and research using Perplexity AI. Use when user says "search", "find", "look up", "ask", "research", or "what's the latest" for generic queries. NOT for library/framework docs (use Context7) or workspace questions.

Perplexity Tools Use ONLY when user says "search", "find", "look up", "ask", "research", or "what's the latest" for generic queries. NOT for library/framework docs (use Context7), gt CLI (use Graphite MCP), or workspace questions (use Nx MCP). Quick Reference Which Perplexity tool? Need search results/URLs? → Perplexity Search Need conversational answer? → Perplexity Ask Need deep research? → Researcher agent ( /research <topic ) NOT Perplexity use these instead: Library/framework docs → Context7 MCP Graphite gt CLI → Graphite MCP THIS workspace → Nx MCP Specific URL → URL Crawler Perplexity Search When to use: Generic searches, finding resources Current best practices, recent information Tutorial/blog post discovery User says "search for...", "find...", "look up..." Default parameters (ALWAYS USE): When to increase limits: Only if: User explicitly needs comprehensive results Initial search found nothing useful Complex topic needs multiple sources Perplexity Ask When to use: Need conversational explanation, not search results Synthesize information from web Explain concepts with current context Usage: NOT for: Library documentation (use Context7) Deep multi source research (use researcher agent) Prohibited Tool NEVER use: mcp perplexity perplexity research Use instead: Researcher agent ( /research <topic ) Token cost: 30 50k tokens Provides multi source synthesis with citations Use sparingly for complex questions only Tool Selection Chain Priority order: 1. Context7 MCP Library/framework docs 2. Graphite MCP Any gt CLI mention 3. Nx MCP THIS workspace questions 4. Perplexity Search Generic searches 5. Perplexity Ask Conversational answers 6. Researcher agent Deep multi source research 7. WebSearch Last resort (after Perplexity exhausted) Examples ✅ CORRECT Use Perplexity Search: "Find postgres migration best practices" "Search for React testing tutorials" "Look up latest trends in microservices" ✅ CORRECT Use Perplexity Ask: "Explain how postgres advisory locks work" "What are the trade offs of microservices?" ❌ WRONG Use Context7 instead: "Search for React hooks documentation" → Context7 MCP "Find Next.js routing docs" → Context7 MCP "Look up Temporal workflow API" → Context7 MCP ❌ WRONG Use Graphite MCP instead: "Search for gt stack commands" → Graphite MCP "Find gt branch workflow" → Graphite MCP ❌ WRONG Use Nx MCP instead: "Search for build config" (in THIS workspace) → Nx MCP "Find project dependencies" (in THIS workspace) → Nx MCP Key Points Default to limited results avoid context bloat Library docs = Context7 ALWAYS try Context7 first "gt" = Graphite MCP ANY "gt" mention uses Graphite Deep research = /research NOT perplexity research tool Fallback chain Search → Ask → WebSearch (last resort)
