 ## Description
 
-Shell a solid to create a hollow part.
+Shell a solid to create a hollow part. The operation can expose these exact
+kernel roles:
+
+- `shell.body_face`: surviving or modified source body faces.
+- `shell.offset_face`: generated offset faces.
+- `shell.closing_descendant`: descendants of removed closing faces.
+- `shell.wall`: generated closing-boundary edges.
+
+The named arguments map directly to those roles. A role is available only when
+OCC provides a complete witness;
+requesting an unavailable role fails instead of deriving one from enumeration or
+geometry. `result_tag` tags the resulting solid. Recorded assignments replay as
+semantic nodes and preserve face versus edge target kinds.
