 - Model implementations should add the minimal number of ComfyUI nodes required
   to run the model. Reuse existing nodes as much as possible; adapting the model
   to work with existing nodes is strongly preferred over creating new nodes.
+- Nodes should output only values they own. Do not add pass-through outputs for
+  workflow convenience unless the node is explicitly an output node. Existing
+  models, latents, conditioning, or other inputs should flow directly to the
+  next consumer instead of being re-emitted unchanged.
+- Nodes should expose only inputs they actually read to produce current
+  behavior. Do not add placeholder, pass-through, compatibility, or
+  workflow-shaping inputs that are ignored or could flow directly to another
+  node.
 - Node-level code must not patch model code directly. Any node behavior that
   modifies, wraps, hooks, or changes model behavior must go through the model
   patcher class instead of reaching into model internals.
