AI Summary

Status: NEEDS_REVIEW

FILE	SUMMARY
services/auth/authapi.proto	Added a new field 'id_of_user' to the GenerateTokenRequest message in the protocol buffer definition.
services/auth/handlers.go	Added a new helper function 'helperSum' that takes two integers and returns their sum.
services/identity/db/identitydb.go	Added a new method 'FetchUser' to the IdentityDB interface and implemented it in the DB struct. This method is similar to the existing 'GetUser' method.

Detailed Comments:

services/auth/authapi.proto

services/auth/handlers.go

• FILE: The added 'helperSum' function appears to be unrelated to the authentication service. Consider removing it if it's not used within the auth service.

services/identity/db/identitydb.go

• FILE: The new 'FetchUser' method is identical to the existing 'GetUser' method. Consider removing one of them to avoid code duplication.
