Final test to verify code extraction implementation is working.
Created: 2025-08-05
Purpose: Final validation of code extraction for Fix 4 (Code Extraction)
Context: Part of MCP Tools Testing issue resolution to implement missing code extraction
This script performs final validation that the code extraction implementation is working
correctly after all fixes have been applied. It verifies that the pipeline properly
extracts, summarizes, and stores code examples from scraped content.
Related outcomes: See mcp_tools_test_results.md - Fix 4 remains incomplete
