Diagnoses and resolves ComfyUI issues across four categories: server errors, workflow errors, quality issues, and performance problems.
| Server | Connection refused, timeouts, crashes | Is ComfyUI running? Check /systemstats | | Workflow | Node errors, missing inputs, type mismatches | Validate workflow against inventory | | Quality | Artifacts, wrong identity, blurry output | Check settings (CFG, weights, resolution) |
| Performance | OOM, slow generation, VRAM errors | Check VRAM usage, model sizes |
Diagnose ComfyUI errors, workflow failures, and quality issues. Suggests fixes based on error patterns, missing dependencies, and community-known workarounds. Use when ComfyUI workflows fail or produce unexpected results. Source: mckruz/comfyui-expert.
