An agent skill that guides AI coding agents through evidence-led web performance optimization, using real-user signals for prioritization and browser traces for diagnosis. It bundles a workflow, a measurement reference, a RUM reference, and a starting performance budget covering critical rendering path, images, fonts, caching, runtime, and third-party scripts.
Reach for it when a user asks to speed up a site, reduce load time, or run a performance audit, so the agent works from measured baselines rather than blind edits.
Use it to
- Establish a field-plus-lab baseline before optimizing
- Optimize critical rendering path and resource loading
- Apply image, font, and caching optimizations
- Fix runtime issues like layout thrashing and long lists
- Manage third-party scripts with facades and load strategies
