What does automation look like, from the perspective of an automation tool developer, or a workflow designer.

* Clarity between concept and code.
* Easy to write.
* Fast feedback when developing automation.
* Provide good UX without needing to write UI code.

### Command Context

At the bottom of every page, we will be building up a `cmd_context`, which holds the information about a workflow. Different commands can be invoked with the `cmd_context` to gather information about the workflow.

```rust ,ignore
let mut cmd_context = CmdContext::builder()
    /* ?? */
    .build();

StatusCmd(&mut cmd_context).await?;
DeployCmd(&mut cmd_context).await?;
```
