## Examples

### Basic Script Only Check

Create instance scan checks that run standalone scripts without table bindings

```typescript
/**
 * @title Basic Script Only Check
 * @description Create instance scan checks that run standalone scripts without table bindings
 */

import { ScriptOnlyCheck } from '@servicenow/sdk/core'

export const adminRoleOveruseCheck = ScriptOnlyCheck({
    $id: Now.ID['check-admin-overuse'],
    name: 'Admin Role Overuse',
    active: true,
    category: 'security',
    priority: '1',
    shortDescription: 'Detects excessive admin role assignments across user accounts',
    script: Now.include('./check-admin-overuse.js'),
    description:
        'Queries sys_user_has_role to identify accounts with admin privileges and flags instances where more than 5% of active users hold the admin role.',
    resolutionDetails: 'Review admin role assignments and replace with more granular roles where possible.',
})

export const orphanedRecordCheck = ScriptOnlyCheck({
    $id: Now.ID['check-orphaned-records'],
    name: 'Orphaned Update Set Records',
    active: true,
    category: 'manageability',
    priority: '4',
    shortDescription: 'Finds update set records referencing deleted metadata',
    scoreMin: 0,
    scoreMax: 50,
    scoreScale: 2,
})

```

**check-admin-overuse.js**

```javascript
;(function checkAdminOveruse() {
    var gr = new GlideAggregate('sys_user_has_role')
    var adminCount = 0
    gr.addQuery('role.name', 'admin')
    gr.addQuery('user.active', true)
    gr.addAggregate('COUNT')
    gr.query()

    if (gr.next()) {
        adminCount = parseInt(gr.getAggregate('COUNT'))
        if (adminCount > 10) {
            finding.increment()
        }
    }
})()
```
