What performance metrics can this skill validate?

It can check various metrics including bundle sizes, page load times, API response times, and Lighthouse scores against your defined thresholds.

Does this skill work with external tools?

It is highly compatible with other plugins and tools that provide raw performance data, such as website speed tests, API monitoring services, or Lighthouse.

How does Claude trigger the performance check?

Claude activates this skill when it detects keywords like 'performance budget', 'validate budget', 'performance regression', or when you explicitly ask to check metrics like 'page load times'.

Can I use this skill in my CI/CD pipeline?

Yes, it is specifically designed to be integrated into build processes to act as a quality gate, preventing code with performance regressions from being merged or deployed.

Do I need to define the budgets myself?

Yes, you define realistic performance thresholds in your project configuration, and the skill compares current application data against those predefined limits.

Analytics & Monitoring

Validates application performance metrics against predefined thresholds to prevent regressions throughout the development lifecycle.

About

The Performance Budget Validator skill enables Claude to monitor and enforce strict performance standards by comparing real-time metrics—such as bundle sizes, page load times, and Lighthouse scores—against specific budget limits. By identifying performance regressions early, it helps developers maintain optimal user experiences and prevents slow code from reaching production. This skill is particularly powerful when integrated into CI/CD pipelines, where it functions as an automated quality gate to ensure every release meets your team's speed and efficiency requirements.
