[duplicate-code] Duplicate Code Analysis Report

[github-actions]

Summary

Analysis of commit d3050f7. Examined 146 non-test Go source files. The codebase is generally well-refactored (the recent commit #8507 specifically addressed 4 duplication findings). One significant duplication pattern meeting the >10-line threshold was identified.

Detected Patterns

This analysis found 1 significant duplication pattern:

1. CompileToolResponseFilter / CompileToolResponseFilterWithVars in jqschema.go — Severity: Medium — See sub-issue [duplicate-code] Duplicate Code Pattern: jq filter compile pipeline duplicated in jqschema.go #8553

Overall Impact

• Total Duplicated Lines: ~20 lines (structural near-duplication across 2 functions of 29 and 33 lines respectively)
• Affected Files: 1 (internal/middleware/jqschema.go)
• Maintainability Risk: Medium — any change to the parse/cache/compile pipeline (e.g., adding metrics, changing error messages, adjusting cache semantics) must be made in two places
• Refactoring Priority: Low-Medium — the duplication is contained to a single file and the two functions are well-named

Next Steps

1. Review the individual pattern sub-issue for detailed refactoring guidance
2. Consider extracting a private compileFilterWithOpts helper as described in [duplicate-code] Duplicate Code Pattern: jq filter compile pipeline duplicated in jqschema.go #8553
