debug-render from artokun/comfyui-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Debug a WRONG or imperfect render (not a hard error) by inspecting inputs and intermediate steps with run-to-node. Render one branch up to an output, preview-tap latents/masks/preprocessor maps, localize the first bad stage, then fix. Use when a final image/video completes but looks wrong, such as artifacts, wrong subject/pose/composition/color, blur, a ControlNet/IPAdapter/mask/LoRA not taking, or a two-stage refiner or upscale degrading the result. For errors/OOM/missing nodes use the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.
## When to reach for this
- A final image/video is wrong: artifacts, wrong subject/pose/composition, off
color, soft/blurry, melted hands, wrong style.
- A conditioner isn't "taking" (ControlNet, IPAdapter, a mask, an inpaint, a
LoRA) and you can't tell if the *input* to it is wrong or the *node* is wrong.
- A multi-stage pipeline (base → refiner, txt2img → upscale, decode → post)
degrades, and you need to see which stage introduces the problem.

How to install
mdr add artokun/comfyui-mcp/debug-render@sha256:951df0175c39586cThe line at the top of this page pins the label git:20260825.cab59a6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
