fix: move copy button - #390

packages/ai-core/src/components/AnalysisResult.tsx (1)

60-70: Avoid any and memoize text aggregation to improve type safety and performance.

Line 65's as any drops type guarantees. Lines 60–70 recompute text aggregation on every render despite being expensive (multiple iterations over arrays). Both 'text' and 'reasoning' message parts have a guaranteed .text: string property per the schema, so a type-safe useMemo wrapper is straightforward.

♻️ Proposed refactor

-import {useEffect, useRef, useState} from 'react';
+import {useEffect, useMemo, useRef, useState} from 'react';

-  const allTextContent = uiMessageParts
-    .filter((part) => part.type === 'text' || part.type === 'reasoning')
-    .map((part) => {
-      if (part.type === 'text' || part.type === 'reasoning') {
-        return (part as any).text;
-      }
-      return '';
-    })
-    .join('\n\n');
+  const allTextContent = useMemo(
+    () =>
+      uiMessageParts
+        .flatMap((part) => {
+          if (
+            (part.type === 'text' || part.type === 'reasoning') &&
+            'text' in part &&
+            typeof part.text === 'string'
+          ) {
+            return [part.text];
+          }
+          return [];
+        })
+        .join('\n\n'),
+    [uiMessageParts],

In `@packages/ai-core/src/components/AnalysisResult.tsx` around lines 60 - 70,
Replace the untyped cast and repeated computation by memoizing the text
aggregation with React's useMemo and using the proper part type narrowing:
compute allTextContent via useMemo(() => uiMessageParts.filter(p => p.type ===
'text' || p.type === 'reasoning').map(p => p.text).join('\n\n'),
[uiMessageParts]) (no "as any"), then derive hasTextContent from that memoized
value; update references to allTextContent and hasTextContent in
AnalysisResult.tsx accordingly so the code preserves type safety and avoids
recomputing on every render.
