const queries = [
  {
    libraryId: "/android/architecture",
    topic: "Clean Architecture implementation",
    tokens: 15000
  },
  {
    libraryId: "/android/dependency-injection",
    topic: "Hilt integration patterns",

  }
];

// Execute queries and combine findings
// Apply comprehensive research to implementation

Library Discovery

// Find available Android libraries
context7_resolve_library({
  libraryName: "Android Jetpack Compose"
})
// Returns: /android/compose

context7_resolve_library({
  libraryName: "Android ML Kit"
})
// Returns: /android/mlkit

Version-Specific Documentation

🔧 Troubleshooting Context7 Issues

Common Issues and Solutions

Library ID Not Found

// Try alternative library names
context7_resolve_library({
  libraryName: "AndroidX Core"
})
// Try: "Android Core", "AndroidX Core KTX"

No Results for Query

Refine Topic: Make topic more specific
Check Spelling: Ensure correct technical terms
Try Alternative Libraries: Use broader or related library IDs
Reduce Token Count: Sometimes smaller queries work better

Outdated Information

Specify Version: Include Android API version in queries
Check Recency: Note when documentation was accessed
Cross-Reference: Validate with official Android documentation
Report Issues: Document any outdated information found

Performance Optimization

Token Efficiency: Use appropriate token counts for query size
Query Specificity: More specific queries often return better results
Batch Queries: Group related queries to reduce overhead
Cache Results: Reuse successful queries for similar tasks

📚 Context7 Best Practices

Query Construction

Be Specific: Use precise technical terms
Include Context: Mention Android version or use case
Specify Format: Request code examples when needed
Limit Scope: Focus on one specific topic per query

Result Evaluation

Check Recency: Ensure information is current
Validate Accuracy: Cross-reference with known best practices
Assess Completeness: Determine if result fully answers the question
Note Gaps: Identify areas where additional research is needed

Integration Practices

Combine with Brave Search: Use for research + implementation
Document Usage: Track effectiveness for continuous improvement
Share Findings: Make successful patterns available to team
Update Guidelines: Refine usage based on experience
