## What check says

```txt title="npx services.dev check"
  ✗ A fill rung could offer a reserved act to someone who doesn't hold its credential. Take the rung out, or add a staff role that holds the credential. The translators Pool's fill rung 'staff 4h' offers translator's Task to your staff, and no staff role holds sworn translator.

```

## The failing file

```ts title="pools/translators.ts"
import { Pool } from 'services.dev'

export const translators = Pool({
  name: 'translators',
  roles: { translator: { credential: 'sworn translator' } },
  join: { name: 'text', languages: 'language[]' },
  verify: 'https://verify.example.test/translators',
  fill: ['raise 10% 2h', 'staff 4h'],
})
```
