- Check the source document for required tools, credentials and supported hosts.
- Describe your input and desired deliverable; review the output against the source material.

API/schema fallback
V3 uses io.ComfyNode, io.Schema, ComfyExtension, and module-level comfy_entrypoint. define_schema and execute are classmethods; execute parameter names equal input ids; return io.NodeOutput in output order. node_id is stable workflow identity; display_name may change. Useful schema tools include io.Autogrow, io.DynamicCombo, and io.MatchType; previews belong in io.NodeOutput, progress uses the runtime execution API, and terminal nodes set is_output_node. Keep tensor batch dimensions: IMAGE [B,H,W,C], MASK [B,H,W]; do not assume a fixed LATENT shape.
V1 uses INPUT_TYPES, RETURN_TYPES, FUNCTION, CATEGORY, and NODE_CLASS_MAPPINGS. Translate deliberately; do not mix registrations.
If a pack ships frontend code, export WEB_DIRECTORY and keep saved widget values JSON-like and stable. Preserve old workflow identity during V1-to-V3 migration by registering the node_replacement; constructing a replacement descriptor alone does nothing.
