model-registry

model-registry is a skill for Claude Code, Codex from sandyup/comfyui-mcp. It costs 91 tokens per session (2,099 once invoked), scanned A, original, MIT.

A reference list of download links, filenames, and ComfyUI folders for model files such as checkpoints, VAEs, text encoders, and LoRAs.

In plain words
What is it for?
Use it when downloading models for Flux, WAN, LTX, Qwen, Z-Image, Stable Diffusion 1.5, or SDXL workflows, including gated Hugging Face or CivitAI downloads.
Why use it?
It helps resolve missing-model errors and reduces confusion about where each model belongs and which exact filename a workflow expects.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

model-registry scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Model Registry

One table per family: filename → source URL → target subdir under <COMFYUI>/models/. Use with download_model(url, target_subfolder, filename). This registry grows with every release — if a model you need is missing, use search_models (HuggingFace) or download_civitai_model and consider contributing the row.

Conventions

  • HF "resolve" URLs download directly: https://huggingface.co/<repo>/resolve/main/<path>
  • 🔒 = gated repo — needs HUGGINGFACE_TOKEN (accept the license on the HF page first)
  • CivitAI model-page URLs need download_civitai_model (resolves version → file); raw civitai.com/api/download/... URLs work with download_model + CIVITAI_API_TOKEN
  • Always verify the exact filename a workflow's loader expects — model-compatibility skill covers which VAE/CLIP pairs with which architecture

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
