Analysis of commit 06ff18a

Summary

This analysis identified 3 significant duplication patterns across the Go codebase, primarily in error handling and HTTP connection logic. While the project has already refactored some areas (e.g., logger initialization with generics), several high-impact patterns remain.

Detected Patterns

This analysis found 3 significant duplication patterns:

1. HTTP Connection Error Checking - Severity: Medium - See sub-issue [duplicate-code] Duplicate Code Pattern: HTTP Connection Error Checking #740
2. SDK CallToolResult Error Returns - Severity: High - See sub-issue [duplicate-code] Duplicate Code Pattern: SDK CallToolResult Error Returns #741
3. Command Error Detection Logic - Severity: Low - See sub-issue [duplicate-code] Duplicate Code Pattern: Command Error Detection Logic #742

Overall Impact

• Total Duplicated Lines: ~45 lines of duplicated logic
• Affected Files: 2 files (internal/mcp/connection.go, internal/server/unified.go)
• Maintainability Risk: Medium - Error handling duplication increases bug risk
• Refactoring Priority: High for pattern Lpcox/initial implementation #2, Medium for pattern Configure as a Go CLI tool #1, Low for pattern Lpcox/initial implementation #3

Next Steps

1. Review individual pattern sub-issues for detailed analysis
2. Prioritize refactoring based on severity and impact
3. Create implementation plan for highest priority patterns
