Research Skill

Research Workflows

Standard Query

1. THINK → Sequential Thinking decomposition
2. RESOLVE → Context7 resolve-library-id
3. DOCUMENT → Context7 query-docs (5000-10000 tokens)
4. SUPPLEMENT → Exa code context search
5. SYNTHESIZE → Structured answer with sources

Complex Investigation

1. DEEP THINK → Multi-hypothesis Sequential Thinking
2. DEEP RESEARCH → Exa deep researcher (45s-2min)
3. MONITOR → Check status until completed
4. VALIDATE → Cross-check Context7 official sources
5. REPORT → Comprehensive solution

Technology Trends

1. WEB SCAN → Exa search latest developments
2. CODE PATTERNS → Exa code context for practices
3. ECOSYSTEM → Company research for key players
4. ANALYSIS → Sequential Thinking for implications
5. RECOMMENDATIONS → Actionable insights

Context7 Usage

typescript
// Step 1: Resolve library ID
mcp__context7__resolve-library-id({
  libraryName: "next.js",
  query: "App Router server actions"
})

// Step 2: Query docs
mcp__context7__query-docs({
  libraryId: "/vercel/next.js",
  query: "server actions authentication"
})
Best Practices:
  • Always 
    resolve-library-id
    BEFORE 
    query-docs
  • Specify 
    topic
    parameter to focus retrieval
  • Start with 5000 tokens, increase to 10000 if needed
  • Handle variations: "nextjs" vs "/vercel/next.js"

Exa Search Types

typescript
// Code context search
mcp__exa__get_code_context_exa({
  query: "Next.js 16 server actions authentication",
  tokensNum: 5000
})

// Web search
mcp__exa__web_search_exa({
  query: "React 2025 best practices",
  type: "auto",
  numResults: 5
})

Exa Deep Research

Reserve for investigations requiring >30min manual effort.
typescript
// Start research
const { taskId } = await mcp__exa__deep_researcher_start({
  instructions: "Compare authentication solutions for Node.js",
  model: "exa-research-pro" // or "exa-research" for faster
})

// Poll until complete
mcp__exa__deep_researcher_check({ taskId })
Models:
  • exa-research
    : Standard depth (15-45s)
  • exa-research-pro
    : Complex topics (45s-2min)

Sequential Thinking

typescript
mcp__sequential-thinking__sequentialthinking({
  thought: "Analyzing authentication approaches",
  thoughtNumber: 1,
  totalThoughts: 5,
  nextThoughtNeeded: true,
  // Optional for revisions:
  isRevision: false,
  revisesThought: null,
  branchId: null,
  branchFromThought: null,
  needsMoreThoughts: false
})
Best Practices:
  • Start with realistic 
    totalThoughts
    , adjust dynamically
  • Use 
    isRevision: true
    to reconsider hypotheses
  • Create branches (
    branchId
    ) for alternatives
  • Set 
    needsMoreThoughts: true
    if incomplete

Multi-Source Synthesis

Parallelization:
  • Run 
    resolve-library-id
    + 
    web_search_exa
    simultaneously
  • Launch multiple Exa searches concurrently
  • Execute Context7 docs + Exa code search in parallel
Source Priority:
  1. Official documentation (Context7)
  2. Recent tutorials (Exa, <6 months)
  3. Older content (with version verification)

Response Format

## 🔍 Research: [Topic]

### Methodology
- Sequential Thinking: [N thoughts, M revisions]
- Context7: [Library@version consulted]
- Exa: [Search types performed]

### Key Findings
1. **[Finding 1]** (Source: [URL])
   - Technical details
   - Code examples

2. **[Finding 2]** (Source: [URL])

### Recommendations
- [Action 1]: [Why + How]
- [Action 2]: [Why + How]

### Sources
- Context7: [Exact library IDs]
- Exa: [X results analyzed]
- Deep Research: [Task ID if used]

Error Handling

Context7 Failures:
  • Verify library name spelling
  • Try different formats ("/org/project" vs "project-name")
  • Fallback to Exa code context
Exa Timeouts:
  • Reduce 
    numResults
  • Simplify query
  • Switch 
    type: "deep"
    → 
    type: "fast"
Sequential Thinking Blocks:
  • Revise with 
    isRevision: true
  • Increase 
    totalThoughts
  • Create new branch

Forbidden Behaviors

  • ❌ Guess library IDs without 
    resolve-library-id
  • ❌ Start deep researcher without checking completion
  • ❌ Mix opinions with facts without distinction
  • ❌ Provide code without version verification
  • ❌ Ignore WebFetch redirects
  • ❌ Recommend without citing sources
  • ❌ Skip Sequential Thinking for multi-step problems
