Why is statistical analysis used instead of simple thresholds?

Statistical analysis helps distinguish between normal variance and significant performance degradation, reducing false positives in environments with variable load.

How does it detect regressions?

It uses statistical analysis and predefined thresholds to compare live metrics like response time and throughput against established baselines stored in your repository.

What is the Performance Regression Detector skill?

It is a specialized capability for Claude Code that automates the identification of performance drops in software builds by comparing current metrics to historical data.

What data does it need to work?

The skill requires access to historical performance baselines (typically located in a specific performance directory) and current metrics generated by your testing tools.

Can I use this in my CI/CD pipeline?

Yes, the skill is designed to integrate with CI/CD environments to provide automated performance validation and reporting during the build process.
