# Keeping listings healthy (/docs/creators/listing-health)



A recipe depends on models and components hosted outside SimpliGen. If one of those disappears upstream, meaning it is removed or made private, the recipe can no longer be installed cleanly.

## Broken listings [#broken-listings]

We check published recipes automatically. If a recipe becomes uninstallable, we mark it broken and email you once. While a recipe is broken:

* **New installs are disabled**, so nobody downloads something that will not work.
* **Existing users keep their installed copy**, so people who already have it are unaffected.

## Fixing a broken recipe [#fixing-a-broken-recipe]

Open SimpliGen, go to the recipe editor, point the recipe at a model or component that is available, and publish again. Once it passes review, it goes back in the store.

## Keeping recipes healthy [#keeping-recipes-healthy]

* Prefer well-established models that are likely to stay available.
* When you swap a model, test the recipe end to end before publishing.
* If you get a broken-listing email, fix it promptly so you do not miss installs.
