3## Positioning
4 
5Treat this skill as an explicit/manual helper for benchmark comparison work.
6 
7## When to Use
8 
9Use this skill when:
10- Identify performance regressions in a CI/CD pipeline.
11- Analyze performance metrics for potential degradation.
12- Compare current performance against historical baselines.
13 
14## Not For / Boundaries
15 
16- Broad optimization roadmap or tuning backlog: use `providing-performance-optimization-advice`
17- Root-cause debugging of a specific slow path: use `systematic-debugging`
18- General test artifact packaging without regression judgment: use `generating-test-reports`
19 
20## Typical Outputs
21 
22- A baseline-vs-current regression summary
23- Severity-ranked regressed metrics
24- Follow-up questions for deeper profiling or investigation
