 The action makes the following AWS CloudFormation API calls depending on the operation mode:
 
 **All Modes:**
+
 - `DescribeStacks` - Check if stack exists and get current status
 - `CreateChangeSet` - Create change set for stack creation or updates
 - `DescribeChangeSet` - Check change set status and retrieve changes
 
 **Create & Execute Mode (default):**
+
 - `ExecuteChangeSet` - Execute the created change set
 - `DescribeStacks` - Get final stack status and outputs after execution
 
 **Create Only Mode:**
+
 - No additional calls (change set left for manual review/execution)
 
 **Execute Only Mode:**
+
 - `ExecuteChangeSet` - Execute existing change set by ID
 - `DescribeStacks` - Get final stack status and outputs after execution
 
 **Error Reporting (when change set creation fails):**
+
 - `DescribeStackEvents` - Retrieve detailed error information for validation failures
 - `DeleteChangeSet` - Clean up failed change sets (unless `no-delete-failed-changeset` is set)
