Documentation comments are helpful in understanding what that part of the code is responsible for. It is always a good idea to add documentation to your code to improve the code readability and maintainability. In addition to that, it becomes helpful when you revisit the code after a long time. Here, the class is missing the doc comment and it is recommended to add it for the reasons discussed above.
If you don't want DeepSource to raise issues for missing doc comments, you can configure it in the
.deepsource.toml configuration file. Please refer to the PHP docs for available options.
