## Use Case

This workflow helps you manage tags that indicate an issue has been fixed. You can customise this workflow to automatically remove or update inappropriate tags based on a change in the issue state.

## Modules

When the state of an issue is set to an unresolved state, this rule removes the confirmed tag from the issue.

### Remove tag when issue changes to an unresolved state

```JAVASCRIPT
const entities = require('@jetbrains/youtrack-scripting-api/entities');
const workflow = require('@jetbrains/youtrack-scripting-api/workflow');

exports.rule = entities.Issue.onChange({
    title: 'Remove tag when issue changes to an unresolved state',
    guard: (ctx) => {
        const issue = ctx.issue;
        return issue.fields.isChanged(ctx.State) && issue.fields.State && !issue.fields.State.isResolved;
    },
    action: (ctx) => {
        const TARGET_TAG_NAME = 'confirmed';
        const issue = ctx.issue;
        const oldValue = issue.fields.oldValue(ctx.State);
        if (oldValue && oldValue.isResolved) {
            issue.removeTag(TARGET_TAG_NAME);
            const wasSuccessfullyRemoved = !!issue.tags.removed.find(function (tag) {
                return tag.name === TARGET_TAG_NAME;
            });
            if (wasSuccessfullyRemoved) {
                workflow.message('Tag "{0}" is removed', TARGET_TAG_NAME);
            }
        }
    },
    requirements: {
        State: {
            type: entities.State.fieldType
        }
    }
});
