 The third argument is JSON input for the method. If the method does not require input, you can omit the third argument (implicitly `{}` passed).
 
+If the method name is "kebab-case", it automatically converts to "PascalCase" (for example, `describe-clusters` -> `DescribeClusters`).
+
+```console
+$ aws-sdk-client-go ecs describe-clusters '{"Cluster":"default"}'
+```
+
+#### Query output by JMESPath
+

+
+```console
+./aws-sdk-client-go ecs DescribeClusters '{"Cluster":"default"}' \
+  --query 'Clusters[0].ClusterArn'
+```
