Identifies performance-critical code changes and recommends specific Criterion benchmarks to prevent regressions.
The Benchmark Advisor skill streamlines the performance optimization workflow by automatically analyzing git diffs to detect changes in performance-sensitive source files. By mapping modified files to their corresponding Criterion benchmark suites via a configurable mapping file, it provides actionable cargo bench commands tailored specifically to your current work. This ensures developers can verify the performance impact of their changes immediately, reducing the risk of accidental regressions and saving significant time by running only the relevant tests rather than the entire project suite.
