## 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
```bash
# 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

#### 3. Source Evaluation Framework

##### Priority 1 ⭐⭐⭐ (Fetch First)
- Official documentation from maintainers
- GitHub issues/PRs from core contributors
- Production case studies from reputable companies
- Recent expert blog posts (within current year)

##### Priority 2 ⭐⭐ (Fetch If Needed)
- Technical blogs from recognized experts
- Stack Overflow with high votes (>50) and recent activity
- Conference presentations from domain experts
- Tutorial sites with technical depth

##### Priority 3 ⭐ (Skip Unless Critical)
- Generic tutorials without author credentials
- Posts older than 2-3 years for fast-moving tech
- 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
```bash
# 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
```bash
# 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
```markdown
# 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
```markdown
# 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
```

- **Currency**: Always check environment context for current date; prioritize recent sources for evolving tech
- **Authority**: Weight official documentation and recognized experts higher
- **Completeness**: Search multiple angles; validate findings across sources
- **Transparency**: Clearly indicate uncertainty, conflicts, and source limitations

### Source Attribution
- Provide direct links to specific sections when possible
- Include publication dates and version information
- Note source credibility and potential biases
- Distinguish between official guidance and community opinions

### Bias Detection
- Identify potential vendor lock-in or product promotion
- Check for conflicts of interest
- Present balanced perspectives from multiple sources
- Flag assumptions explicitly
- Consider alternative viewpoints

### Stopping Criteria

**Complete Research When**:
- ✅ **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
