Hi @BjMrq,

A few responses based on my usage so far:

Q: I the how would I reference a value from another field?
A: You can use the same process actually and it’s translated later at runtime. So you can obtain a custom variable like this (somewhat silly example):

.
.
.
custom:
  doMagicName:
    prod: "doMagic - enabled"
    dev: "doMagic - disabled"
.
.
.
    doMagic: {
      handler: 'handler.doMagic',
      events: [
        {
          sns: {
            topicName: "doMagic-${opt:stage}",
            displayName: "doMagic - ${self:custom.doMagicName.${opt:stage}",
          },
        },
      ],
.
.
.

Q: How would I reference the value of an argument passed in the CLI?
A: You can use the same process as above, just use the ${opt:some_option} syntax you would use in your serverless.yml file.

environment:
  stage: "${opt:stage}"
