+## AWS Permissions
+
+To use the application fully, the active AWS identity needs read-only access to SQS, SNS, and CloudWatch in the selected account and region.
+
+Minimum permissions for the existing browse/detail flows:
+
+- `sqs:ListQueues`
+- `sqs:GetQueueAttributes`
+- `sns:ListTopics`
+- `sns:GetTopicAttributes`
+- `sns:ListSubscriptions`
+- `sns:ListSubscriptionsByTopic`
+- `sns:GetSubscriptionAttributes`
+
+Additional permission for the SQS insight block in queue detail:
+
+- `cloudwatch:GetMetricData`
+
+If `cloudwatch:GetMetricData` is missing, the queue detail still opens and raw SQS attributes still work, but the insights block will show partial/unavailable values and the status bar will display a warning.
