Performance Monitoring (WebF)

Help the user measure and improve performance (especially LCP) for WebF content.

Steps

1. If the user passed $ARGUMENTS, treat it as the directory to inspect; otherwise use the current working directory.
2. Call mcp__openwebf__project_profile with { "cwd": "<dir>" } and summarize perf signals/findings.
3. Call mcp__openwebf__docs_search for “Performance Monitoring” and “Debugging and Performance” (prefer code snippets).
4. Provide:
   • Which metrics to capture (FP/FCP/LCP/DCL/load)
   • How to dump detailed state (dumpLoadingState)
   • LCP content verification
5. Recommend best practices:
   • Leverage async rendering
   • Use native components for performance-critical UI
   • Minimize native binding calls
6. If the user wants scaffolding, offer templates:
   • perf/loading-state-events
   • perf/loadingstate-dump
   • perf/lcp-content-verification
