The complete audit workflow# With Claude Code or Gemini, Chrome DevTools MCP, and the WebPerf SKILLs installed, the complete audit workflow goes from a series of scattered manual actions to a process the agent runs end to end: 1. Navigate to the URL (navigate_page) 2. Measure Core Web Vitals → run LCP.js, CLS.js, INP.js 3. If LCP > threshold → run LCP-Sub-Parts.js 4. If TTFB > threshold → run TTFB-Sub-Parts.js 5. Analyze resources → run Render-Blocking.js, Preload-Async-Conflicts.js 6. Collect all JSON results 7. Generate report with diagnosis, prioritization, and concrete solutions 8. Export in the required format (markdown, PDF, Slack)
A measurement that varies with the model's interpretation is not a measurement. It's an estimate.
I've written about separating deterministic measurement from AI analysis in web performance audits.
