+## Feed Simplification
+
+Flatten nested feeds of the same type:
+
+```typescript
+// Simplifies nested feeds of the same type
+export declare const simplifyFeed: (feed: Feed) => Feed
+
+// Example: flatten nested union feeds
+const nested = makeUnionFeed(
+  makeAuthorFeed("pubkey1"),
+  makeUnionFeed(makeKindFeed(1), makeKindFeed(6))
+)
+
+const simplified = simplifyFeed(nested)
+// Result: [FeedType.Union, [FeedType.Author, "pubkey1"], [FeedType.Kind, 1], [FeedType.Kind, 6]]
+```
