Start an analysis for each URL with `analyze_site`.\n2. Check both jobs with `get_analysis_status`.\n3. After both are complete, call `compare_sites` with the two task IDs.\n4. Explain the returned metric deltas and finding differences.\n5. Do not invent measurements or infer findings not present in the tool output.\n6. Preserve uncertainty when a metric is unavailable.\n7. Include each report URL when available. \n\n8. Performance metric deltas relate to the scanner's load-time heuristic;\n   do not present them as PageSpeed/Lighthouse differences without distinct\n   PageSpeed data for both URLs.\n\n"
