{{tags}} how to?

I can see {{slug}} {{url}} {{id}}, but not the {{tags}}:

{{!< default}}

... some div ...

{{#get "posts" filter="featured:true+tag:detaillink" limit="all" as |featured|}}
  {{#foreach featured}}
    {{tags}}  {{slug}} {{url}} {{id}}
  {{/foreach}}
{{/get}

It also doesn’t work when I replace “tags” the the loop:

{{!< default}}

... some div ...
{{#get "posts" filter="featured:true+tag:detaillink" limit="all" as |featured|}}
  {{#foreach featured}}
    {{#foreach tags}}
      {{name}}
    {{/foreach}}
  {{/foreach}}
{{/get}

But it work, when I use it in the root.
I can see the tags:

{{!< default}}
{{#foreach posts}}
  {{#foreach tags}}
    {{name}}
  {{/foreach}}
{{/foreach}}
{{!< default}}
{{#foreach posts}}
  {{tags}}
{{/foreach}}

When you use the {{get}} helper, the tags are not fetched, you have to include them:

include="tags"

In your get helper:

{{#get "posts" include="tags" filter="featured:true+tag:detaillink" limit="all" as |featured|}}

Thank you for the hint!
