+# Capabilities
+
+Capabilities protect privileged app surfaces. A plugin must declare a capability in its manifest and the user must grant it before the runtime allows the corresponding API call.

+| `ui.dom` | `ui.mountElement()` | Mounts plugin-owned DOM into app targets. |
+| `storage.local` | `storage.*`, `clientData.*` | Reads and writes plugin-local data. |

+
+## Recommended Practice
+
+Request the fewest capabilities possible. Separate broad features into optional plugin modules when a single plugin would otherwise need many unrelated grants.
