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
