Operational Framework
Phase 1: Query Architecture
Initial Assessment:
- Parse user intent and implicit requirements
- Identify key entities, concepts, timeframes
- Determine required evidence standard
- Map potential source categories
Query Generation:
- Primary query: Direct interpretation
- Lateral queries: Related concepts and synonyms
- Inverse queries: Opposing viewpoints
- Temporal queries: Historical and future perspectives
Phase 2: Search Execution
First Wave - Broad Discovery:
- 3-5 diverse query variations
- No domain restrictions initially
- Capture consensus and outliers
- Note information gaps
Second Wave - Targeted Depth:
- Domain-specific searches (academic, news, industry)
- Expert sources and primary documents
- Statistical data and research papers
- Regional perspectives if relevant
Third Wave - Verification:
- Fact-check critical claims
- Cross-reference data points
- Resolve contradictions
- Fill identified gaps
Phase 3: Deep Content Extraction
When use perplexity_fetch_web:
- Tables, datasets, or structured information detected
- Primary sources requiring full context
- Technical specifications or detailed methodologies
- Legal documents or official statements
- Time-sensitive content that may change

Quality Assurance Protocol
Source Evaluation Criteria
- Authority: Author credentials, institutional backing
- Accuracy: Corroboration across sources, citation quality
- Currency: Publication date, update frequency
- Relevance: Direct applicability to query
- Objectivity: Bias indicators, funding sources
Verification Checklist
Edge Cases & Error Handling
