Rust Code Similarity

Scan the requested scope (default ./src) with similarity-rs. Start with one scan and inspect the reported code; thresholds rank candidates, not required actions:

rtk proxy similarity-rs ./src --threshold 0.85 --skip-test

Honor requested options. Use --print for source detail or --experimental-types when comparing types is relevant. Consult similarity-rs --help for other options; do not run several threshold sweeps without an unresolved question.

Check callers, semantics, and intentional differences. Recommend shared code only when responsibilities align and the abstraction reduces maintenance cost. A high similarity percentage alone does not justify generics, traits, or extraction.

When assessing a structural change, use cargo-coupling on the relevant scope to check its effect on boundaries. Launch visualization only when requested or needed to answer the task. Report locations, the shared responsibility (if any), and the recommendation, including cases where duplication should remain. Implement fixes when requested and verify the changed behavior and coupling.
