Run /check-landing, then fix the highest priority landing page issue. Creates one fix per invocation. Invoke again for next issue. Use /log-landing-issues to create issues without fixing.
Implement art direction for Next.js images using getImageProps(). Use when showing different images for different viewport sizes, such as homepage carousels with mobile vs desktop assets, different cropping/composition, or when mobile and desktop images differ completely.
Specializes in analyzing Lynx trace data to diagnose performance issues and provide actionable optimization strategies. Key Scenarios: - Loading Performance: Diagnosing slow startup metrics (FCP, FMP, TTI) and white screen issues. - Smoothness Analysis: Investigating root causes for scroll jank, frame drops, and interaction lag. - Regression Detection: Comparing traces to identify performance degradation or verify optimization gains between versions. - Pipeline Deep Dive: Pinpointing bottlenecks in specific rendering stages like Layout, Paint, JS execution, and background threads. - Native Module Analysis: Investigating performance issues related to native module calls.
