# `import.unknown`

Import names nothing in its folder.

Area 1, [Project layout and modules](../topics/project-layout-and-modules.md); not declinable; the next step is usually the agent's.

A `use` line names a domain, a folder of a domain or of `shared/`, or a
root file, and only names that are there. A name imported from the wrong
folder gets the edit that moves it:



```jadpo
use shared/failures { Stock }

action stock_loaf(each: Stock) -> Stock {
    return each
}
```

```text
error: `Stock` isn't in `shared/failures`
 --> domains/bakery/actions/stock_loaf.jadpo:1:23
  |
1 | use shared/failures { Stock }
  |                       ^^^^^ not in this folder
  reason: A `use` line brings in names from the folder it names; `Stock` is a type in `shared/types/stock.jadpo`, so it comes in from `shared/types`.
  next: Import `Stock` from `shared/types` (agent)
