    ⍟ These new definitions are ok to `add`:
    
      type Foo

  I found and typechecked these definitions in scratch.u. If you
  do an `add` or `update`, here's how your codebase would
  change:
  
    ⍟ These names already exist. You can `update` them to your
      new definition:
    
      type Foo

```
``` ucm
scratch/main> update

  Okay, I'm searching the branch for code that needs to be
  updated...

  Done.
