Response Enrichment & Data Transformation

[mheadd]

Summary

Add Computed Fields

// In internal/models/types.go
type Park struct {
    // ...existing fields...
    
    // Enriched fields for better LLM understanding
    Summary          string   `json:"summary,omitempty"`           // One-sentence description
    BestTimeToVisit  string   `json:"best_time_to_visit,omitempty"` // Derived from weather patterns
    AccessibilityLevel string `json:"accessibility_level,omitempty"` // Easy/Moderate/Difficult
    CrowdLevel       string   `json:"crowd_level,omitempty"`        // Low/Medium/High (seasonal)
}

Example Handler Enhancement

// In internal/mcp/handlers.go
func (s *Server) handleGetParkDetails(ctx context.Context, input GetParkDetailsInput) (*GetParkDetailsOutput, error) {
    park, err := s.npsClient.GetParkDetails(ctx, input.ParkCode)
    if err != nil {
        return nil, err
    }
    
    // Enrich with computed insights
    park = enrichParkData(park)
    
    return &GetParkDetailsOutput{Park: park}, nil
}

func enrichParkData(park *models.Park) *models.Park {
    // Generate concise summary from description
    park.Summary = generateSummary(park.Description, 150) // 150 char max
    
    // Add seasonal recommendations
    park.BestTimeToVisit = determineBestSeason(park)
    
    return park
