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

Phase 2: Information Gathering

1. Strategic Searches

# Progressive search methodology
# Round 1: Broad, orienting search
websearch query: "[topic] overview 2025"

# Round 2: Targeted, specific searches
websearch query: "[topic] technical implementation guide"
websearch query: "[topic] best practices 2025"

# Round 3: Deep dive searches
websearch query: "[topic] architecture comparison analysis"
websearch query: "[topic] detailed technical documentation"

2. Source Discovery

• Official Documentation: Vendor docs, RFCs, specifications
• Expert Blogs: Recognized industry experts, engineering teams
• Academic Sources: Papers, conference proceedings, journals
• Community Resources: GitHub issues, Stack Overflow, forums
• Repositories: Source code with maintenance analysis

• Forum discussions without clear resolution
• Marketing/promotional content

Red Flags 🚫 (Avoid)

• AI-generated content farms
• Duplicate content aggregators
• Paywalled content without abstracts
• Sources contradicting official docs without justification

Phase 3: Content Analysis

1. Content Fetching

# Use WebFetch to retrieve full content
webfetch url: "https://official-docs-url"

# Analyze documentation structure
# Extract key sections, examples, code snippets
# Identify version information and dates

2. Repository Analysis

# Analyze repository health
# Check: Last commit frequency, recent activity
# Check: Open issues, issue handling responsiveness
# Check: Release frequency and versioning
# Check: Star/Fork count (GitHub), contributors

# Example repository health metrics
git -C /path/to/repo log --oneline -20
git -C /path/to/repo log -1 --format="%cd" --since="6 months ago"
gh repo view [owner/repo] --json | jq '.stargazersCount, .forksCount'

3. Cross-Reference and Synthesis

# Compare findings from multiple sources
# Identify consensus and disagreements
# Note version-specific information
# Highlight conflicting information with context

Phase 4: Analysis and Synthesis

1. Pattern Recognition

• Identify recurring patterns across sources
• Detect emerging trends or best practices
• Recognize anti-patterns and common mistakes
• Extract successful implementation approaches

2. Bias Detection

• Identify potential biases in sources
• Check for vendor lock-in or product promotion
• Look for conflicts of interest
• Present balanced perspectives

3. Quality Assessment

• Accuracy: Quote sources precisely
• Currency: Check publication dates (note age of information)
• 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

Phase 5: Reporting

- ✅ Consensus Found: 3+ authoritative sources agree on approach
- ✅ Official Guidance Located: Found maintainer recommendations or official docs
- ✅ Actionable Path Clear: Have specific next steps and implementation guidance
- ✅ Time Limit Reached: Hit depth-appropriate time-box with adequate information

Continue Research If:
- ⚠️ Conflicting Information: Sources disagree without version/context explanation
- ⚠️ Outdated Sources Only: All sources >2 years old for fast-moving tech
- ⚠️ No Official Source: Haven't found maintainer or official documentation
- ⚠️ Unclear Actionability: Can't determine specific next steps
- ⚠️ 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
