I can't share any code without specific goals... but I can point you to the correct apis

https://docs.atlassian.com/software/jira/docs/api/8.5.1/com/atlassian/jira/issue/fields/config/manager/FieldConfigSchemeManager.html

and 

https://docs.atlassian.com/software/jira/docs/api/8.5.1/com/atlassian/jira/issue/fields/config/FieldConfigScheme.html

With these you can create/update the contest (name description, project, issuetype).

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.config.FieldConfigScheme
import com.atlassian.jira.issue.context.ProjectContext
def fieldConfigSchemeManager = ComponentAccessor.fieldConfigSchemeManager
def customFieldManager = ComponentAccessor.customFieldManager
def customField = customFieldManager.getCustomFieldObjectsByName('Scrum Team').first()
def project = ComponentAccessor.projectManager.getProjectByCurrentKey('JSP')
def configurableField = ComponentAccessor.fieldManager.getConfigurableField(customField.id)
def fieldConfigScheme = fieldConfigSchemeManager.getConfigSchemesForField(configurableField).find { config ->
   config.contexts.any { context ->
      context.projectObject?.key == project.key
   }
}
if(!fieldConfigScheme){
   //create one
   def configScheme = new FieldConfigScheme.Builder().setName("some name").setDescription("some desc").toFieldConfigScheme()
   def projectContext = new ProjectContext(project.id, ComponentAccessor.projectManager)
   fieldConfigScheme = fieldConfigSchemeManager.createFieldConfigScheme(configScheme, [projectContext] as List, [null] as List, configurableField)
}
def context = fieldConfigScheme.contexts.find{ it.projectObject.key == project.key}

def fieldConfig = customField.getRelevantConfig(context) // << this can be used to create/delete/update options using optionsManager
//get the default value
customField.customFieldType.getDefaultValue(fieldConfig)
//set the default value
def newDefault = '' // depends on the field type, may need to be an option object is custom field is a select
customField.customFieldType.setDefaultValue(fieldConfig, newDefault)
