# Cosmo Detach Proxy Asset Action

The **Cosmo Detach Proxy Asset Action** node removes (detaches) the proxy media from an existing asset in Cosmo.

To remove a proxy, the **Asset ID** must be provided. The ID can typically be retrieved using the wildcard [{job.assetid}](/helmut4-releases/helmut4-components/streamdesigner/wildcards/job-related-wildcards-32/job-assetid.md).

After execution, the asset will no longer be linked to its proxy file.

#### Synchronization Behavior

**Auto Sync**\
If enabled, the change is synchronized automatically when the project is opened.\
If disabled, the panel will indicate that synchronization is required. An orange counter icon shows how many assets still need to be synchronized or updated, and the user must initiate the sync manually.

#### Execution Notes

* Requires a valid existing asset in Cosmo
* Only removes the proxy link (the media file itself is not deleted from storage)
* Does not return a status result to the stream
