performance-profiling

To profile web application performance, this skill accepts input URLs or code paths to run deterministic tests using standard tools like Lighthouse and DevTools, generating live reports with measurable scores. It integrates these profiling tools into a guided workflow to measure key runtime metrics.

Performance baseline measurement is established by running the profiling script against your target URL or local code path to capture key metrics. This creates a deterministic baseline that you can use to track performance changes and guide targeted improvements over time.

Yes, performance profiling can be applied to CI pipelines and desktop software, not just web apps. The skill operates across development stages from local baselines to production monitoring, accepting code paths to run deterministic tests and report scores for various software environments.

To identify frontend and backend bottlenecks, the skill profiles your application by measuring key metrics and reporting scores. It provides a structured approach to analyze runtime performance, pinpointing bottlenecks across your stack to guide targeted optimization improvements.

Yes, performance measurement requires instrumentation with standard profiling tools like DevTools and Lighthouse. The skill integrates these existing tools into its workflow, using your input URLs or code paths to run deterministic tests rather than replacing your current profiling utilities.

The limitations of standard profiling tools for runtime measurement involve their requirement for explicit instrumentation and deterministic test inputs. This skill relies on accepting valid URLs or code paths to function correctly, meaning uninstrumented code or inaccessible environments will limit its reporting capabilities.
