ComfyUI Portable Skill

Use this skill when the task is to work with ComfyUI in a reusable, installation-agnostic way.

Minimum trigger scope

Trigger on requests like:

• "Build a ComfyUI workflow"
• "Fix this ComfyUI workflow"
• "Use the ComfyUI API"
• "Why is this ComfyUI graph failing?"
• "Add a LoRA / model / node to this ComfyUI setup"

Do not assume any particular machine, model inventory, file layout, GPU, or custom node pack.

First move: assume zero install knowledge

Before writing or editing any workflow:

1. Read references/setup.md.
2. If the install is unknown, collect the missing setup fields from the user or discover them from the running ComfyUI instance.
3. Prefer discovery over assumptions:
   • use /object_info to detect node classes and model dropdown values
   • confirm checkpoints, VAEs, encoders, and LoRAs from the target install
   • stop and report missing requirements clearly

Read path by task

• Setup / first run / portability questions -> references/setup.md
• API submission / queue / history / WebSocket -> references/api.md
• Programmatic graph building -> references/workflow-patterns.md
• Model-family requirements -> references/models.md
• Cross-family validation / node availability -> references/compatibility.md
• LoRA loading and compatibility -> references/lora.md
• Prompt construction -> references/prompting.md
• Graph hygiene / debugging -> references/graph-conventions.md
• Release history -> references/changelog.md
• User-fill config template -> references/config-template.md

Global operating rules

• Treat node classes as discoverable, not guaranteed constants.
• Treat model filenames as examples until confirmed on the target install.
• Use filename-only model references in workflow JSON unless the install explicitly requires a subdirectory path.
• Use defensive parsing for /history and /object_info; schema details can vary by ComfyUI version and custom nodes.
• Fail fast when a required node class, model, or custom node is missing.
• Keep setup-specific notes out of this file; put them in a per-user config or setup reference.

Cold-read test

Before publishing or packaging changes, check that a fresh reader could answer:

• What does this skill do?
• When should it trigger?
• What must be discovered first?
• Where do install-specific values go?
• Which reference file should be opened for the current task?
