+To stop the running session before the configurable `IdleRuntimeSessionTimeout` (defaulted at 15 minutes) and save on any potential runaway costs, execute: `StopRuntimeSession`
+
+Create a file named `stop-runtime-session.ts` with the following content:
+
+###### Example
+    
+    
+    import {
+      BedrockAgentCoreClient,
+      StopRuntimeSessionCommand
+    } from '@aws-sdk/client-bedrock-agentcore';
+    
+    const client = new BedrockAgentCoreClient({ region: 'us-west-2' });
+    const agentArn = 'Agent ARN';
+    const command = new StopRuntimeSessionCommand({
+      agentRuntimeArn: agentArn,
+      runtimeSessionId: randomUUID(),
+      qualifier: 'DEFAULT',
+    });
+    
+    const response = await client.send(command);
+    console.log('Session stopped:', response);
+                
+
+Run the code with the following command:
+    
+    
+    npx tsx stop-runtime-session.ts
