AI Analysis
●●SolidBig BrainSolve My Problem
Structural fingerprinting beats text matching for AI-generated code duplication.
Strengths
- •Tree-sitter parsing fingerprints code structure, not text, catching renamed duplicates.
- •Slop score quantifies deletable duplication as actionable technical debt metric.
- •History command charts duplication trends across git log to pinpoint when it spiked.
Weaknesses
- •Duplicate detection is a solved category with many existing tools and linter integrations.
- •No IDE integration mentioned, requires running CLI separately from development workflow.
