When your ComfyUI workflow throws a cryptic error or generates burned faces at 1024x1024, this skill walks you through systematic diagnosis. It classifies issues into server, workflow, quality, or performance buckets, then matches against a database of known patterns like CUDA OOM fixes, missing custom nodes, or InstantID overexposure. The quick reference covers the top 10 errors with actual solutions, not guesses. Honestly most useful when you're staring at "Expected scalar type BFloat16 but found Float" at 2am and just need someone to tell you to add the force-fp16 flag. It also handles the tedious stuff like mapping node types to their source packages and telling you exactly where to download missing models.
