What the report means

Node types are the classes named by the graph. Model filenames are named weight references found in supported loader inputs or widgets. The report cannot inspect your computer, identify every custom dependency, check a model’s licence or prove it will fit in memory.

If a referenced filename contains NSFW or porn, the report flags that wording. A name without those markers is not a guarantee of SFW content.

Check a workflow manually

  1. Open the JSON in a text editor without running it.
  2. In a visual graph, inspect each node’s type and widget values. In an API prompt, inspect class_type and inputs.
  3. Find the loader’s checkpoint, diffusion model, text encoder, VAE and LoRA names.
  4. Compare them with the workflow’s source instructions and your installed files. File extensions and names alone do not establish compatibility.
