ComfyUI media workflow production

Use this skill to turn a creative or technical brief into a production-ready ComfyUI workflow package. Treat ComfyUI as a graph-based media production runtime, not as a prompt box. Your output should make the graph reproducible, reviewable, safe to run, and easy for another operator or system to execute.

This is provider-independent. Do not assume a specific checkpoint, hosted Comfy service, custom node set, or cloud vendor unless the user or the existing project explicitly names one. Re-check ComfyUI, custom-node, model, license, and cloud API facts at production time because they change frequently.

Operating principles

• Start from the deliverable and constraints, then choose graph topology, models, nodes, and runtime. Do not start by pasting a popular workflow.
• Separate documented facts from production heuristics. Documented facts come from current docs, model cards, licenses, API schemas, and direct tests. Heuristics are your production judgment.
• Keep two workflow artifacts when possible:
  • workflow.json: frontend/save-format graph with layout, grouping, notes, and operator readability.
  • workflow_api.json: API-format graph for programmatic execution.
• Keep enough metadata to recreate a run: workflow JSON, input files with hashes, model identifiers and hashes, custom-node repo revisions, ComfyUI version, parameters, seed policy, hardware/runtime, output paths, and QA notes.
• Prefer fewer custom nodes and fewer model dependencies unless the creative requirement genuinely needs them. Every custom node is code execution and supply-chain risk.
• Never treat model availability as rights clearance. A file being downloadable does not mean the project can use it commercially, use its outputs freely, train on outputs, or use a person's likeness.
• Decide intentionally whether workflow metadata should be embedded in outputs. Embedded graphs aid reproducibility, but may leak prompts, model names, private paths, client references, API node titles, or workflow IP.
