Research Methodology

Phase 1: Planning

1. Analyze Research Query

• Parse User Intent: What is being asked?

• Identify Domain: Technical, academic, business, etc.

• Determine Scope: How deep does the analysis need to be?

• Assess Complexity: Simple, Standard, or Deep research required?

• Set Time Constraints: Quick (15-20 min), Standard (30-45 min), or Deep (60-90 min)?

2. Define Success Criteria

• Information Quality: Specific, accurate, current, well-sourced

• Analysis Depth: Multi-layered, covers all perspectives

• Credibility: Sources are authoritative and actively maintained

• Actionability: Clear recommendations with implementation guidance

• Authority: Prioritize official sources and recognized experts

• Completeness: Search multiple angles, identify gaps

• Transparency: Clearly indicate uncertainty, conflicts, and limitations

4. Inference and Reasoning

Apply multi-step logical analysis

Use Bayesian reasoning for probability assessment

Consider multiple hypotheses and weigh evidence

Identify assumptions and validate them

Reason from first principles when appropriate

• ⚠️ Conflicting Information: Sources disagree without version/context explanation

Best Practices

DO:

✓ Check environment context for current date before all research ✓ Use current year in searches for best practices and evolving technologies ✓ Apply progressive search strategy to avoid over-researching simple queries ✓ Prioritize official sources and cross-reference findings ✓ Provide direct links with specific section references when possible ✓ Note publication dates relative to current context ✓ Be transparent about source limitations and research gaps ✓ Focus on actionable insights with concrete examples ✓ Assess repository health: Check maintenance status, commit frequency, issue responsiveness ✓ Validate dates: Note when sources were last updated relative to current context

DON'T:

✗ Stop at first results without validation from multiple sources ✗ Ignore publication dates when evaluating source relevance ✗ Trust unverified sources without authority assessment ✗ Make assumptions without evidence-based support ✗ Omit source attribution or direct links ✗ Over-research simple questions - match depth to query complexity ✗ Present conflicting information without clear context or resolution ✗ Consider only recent sources - older sources may still be valuable for stable topics ✗ Ignore repository maintenance status - inactive repos may indicate abandoned projects
