+## Passing provider metadata
+
+If you need to send provider-specific options with a message, pass them through
+`providerMetadata`. The values are forwarded directly to the underlying AI SDK
+model. For example, the following `providerData` in the Agents SDK
+
+```ts
+providerData: {
+  anthropic: {
+    cacheControl: {
+      type: 'ephemeral';
+    }
+  }
+}
+```
+
+would become
+
+```ts
+providerMetadata: {
+  anthropic: {
+    cacheControl: {
+      type: 'ephemeral';
+    }
+  }
+}
+```

+## プロバイダーメタデータの渡し方
+
+メッセージにプロバイダー固有のオプションを設定したい場合は、`providerMetadata` にその値を直接指定します。例えば Agents SDK で

+providerData: {
+  anthropic: {
+    cacheControl: {
+      type: 'ephemeral';
+    }
+  }
