CHANGES: 1. **Fixed 9 PDF Scraper Test Failures:** - Added .get() safety for missing page keys (headings, text, code_blocks, images) - Supported both 'code_samples' and 'code_blocks' keys for compatibility - Fixed extract_pdf() to raise RuntimeError on failure (tests expect exception) - Added image saving functionality to _generate_reference_file() - Updated all test methods to override skill_dir with temp directory - Fixed categorization to handle pre-categorized test data 2. **Fixed 25 MCP Test Skips:** - Renamed mcp/ directory to skill_seeker_mcp/ to avoid shadowing external mcp package - Updated all imports in tests/test_mcp_server.py - Simplified skill_seeker_mcp/server.py import logic (no more shadowing workarounds) - Updated tests/test_package_structure.py to reference skill_seeker_mcp 3. **Test Results:** - ✅ 297 tests passing (100%) - ✅ 0 tests skipped - ✅ 0 tests failed - All test categories passing: * 23 package structure tests * 18 PDF scraper tests * 67 PDF extractor/advanced tests * 25 MCP server tests * 164 other core tests BREAKING CHANGE: MCP server directory renamed from `mcp/` to `skill_seeker_mcp/` 📦 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
