Enhanced Web Search Command

Implements robust web search functionality that handles various blocking mechanisms and URL content extraction:

Features

• Advanced retry logic for failed requests
• Multiple search engine integration
• Request header manipulation to avoid detection
• Connection pooling and timeout management
• Result caching to reduce repeated requests
• Proxy support with rotation
• Rate limiting compliance
• URL Content Extraction: Direct content extraction from URLs and permalinks

Usage

Web Search

/search-plus "Claude Code plugin documentation"
/search-plus "best practices for API rate limiting"

URL Content Extraction

/search-plus "https://docs.anthropic.com/en/docs/claude-code/plugins"
/search-plus "https://github.com/example/repo"
/search-plus "https://example.com/article"

Error Handling

• Automatic retry for 403 Forbidden errors
• Schema validation error handling for 422 Unprocessable Entity errors
• API version compatibility and "Did 0 searches..." scenarios
• Rate limiting detection and 429 error handling
• Connection refused error handling
• Timeout management with configurable limits
• Fallback to alternative search engines when primary fails
• URL extraction error recovery with retry logic
• Query reformulation and parameter simplification for validation errors

Implementation

This command enhances Claude Code's existing search functionality by adding comprehensive error handling specifically designed to work around rate limiting, blocking mechanisms, and API validation issues that cause 403, 422, 429, and ECONNREFUSED errors.

The process follows this flow:

1. Input Detection: Determine if input is a search query or URL
2. For URLs: Extract content directly using Tavily Extract API with retry logic
3. For Queries: Perform web search with enhanced error handling
4. Error Recovery: If errors detected (403, 422, 429, ECONNREFUSED, schema validation):
   • Classify error type and determine retry strategy
   • For 422 errors: Reformulate query, adjust parameters, simplify request structure
   • For 403/429 errors: Apply exponential backoff, header rotation, jitter
   • For ECONNREFUSED: Retry with alternative connections and increased timeouts
   • If retry fails, try alternative search method
5. Return Results: Formatted results with extraction metadata when applicable
