What Debug Render does

Debug Render localizes wrong but completed ComfyUI outputs by rendering one branch to an output node and inspecting intermediate images, latents, masks, and preprocess maps. Use it when a final image or video has artifacts, wrong composition, or a conditioner is not taking effect.

Debug Render is cataloged under Quality on DirSkills. Debug Render comes from a repository tagged agent-skills, ai-agent, claude-code, claude-plugin and comfyui.

README

Excerpt

Debugging renders with run-to-node

When a final asset looks wrong (not when it errors), don't re-roll the whole graph and hope. Localize the fault: render only as far as one stage and LOOK at what that stage actually produces. The wrong-looking output is downstream of a first bad step — find that step, fix it there, and everything after it follows.

The tool for this is panel_run with to_node_id ("run to node"), which uses ComfyUI's native partial execution: only the target output node plus everything upstream of it renders; every other branch is skipped. That makes each probe fast and cheap, and the output is delivered to you automatically (same as any run — don't poll).
