Performance Regression Detector

Positioning

Treat this skill as an explicit/manual helper for benchmark comparison work.

When to Use

Use this skill when:

Identify performance regressions in a CI/CD pipeline.
Analyze performance metrics for potential degradation.
Compare current performance against historical baselines.

Not For / Boundaries

Broad optimization roadmap or tuning backlog: use providing-performance-optimization-advice
Root-cause debugging of a specific slow path: use systematic-debugging
General test artifact packaging without regression judgment: use generating-test-reports

Typical Outputs

A baseline-vs-current regression summary
Severity-ranked regressed metrics
Follow-up questions for deeper profiling or investigation
