Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00825 |
| Opus 5.5 | $0.00023 | $0.00330 |
| Sonnet 5.5 | $0.00011 | $0.00165 |
| Haiku 4.5 | $0.00006 | $0.00082 |
Grade A, and why
comfyui-workflow-analysis 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 today.
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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ComfyUI Workflow Analysis
Reads a workflow JSON and produces a complete setup checklist: custom nodes to install and models to download/place.
When to Use
- User shares a downloaded workflow JSON file
- User asks "what custom nodes does this need?"
- User asks "what models does this workflow use?"
- User wants to get a new workflow running
Instructions
Step 1 - Read the workflow JSON
Read the file and extract all unique class_type values from the nodes array.
Step 2 - Separate built-in vs custom nodes
Built-in nodes (no install needed) include:
KSampler, CLIPTextEncode, VAEDecode, VAEEncode, CheckpointLoaderSimple, LoraLoader, ControlNetLoader, ImageScale, SaveImage, PreviewImage, LoadImage, EmptyLatentImage, LatentUpscale, ConditioningCombine, ConditioningSetArea, CLIPSetLastLayer, UNETLoader, DualCLIPLoader, VAELoader, FluxGuidance, ModelSamplingFlux, BasicGuider, BasicScheduler, SamplerCustomAdvanced, RandomNoise, CFGGuider
Everything else is likely a custom node.
Step 3 - Map custom nodes to repos
Most follow the pattern ComfyUI-RepoName or similar. For each custom node class:
- Identify the likely repo name from the class prefix/naming
- Check if it matches any of the user's already-installed nodes in
<ComfyUI install>\custom_nodes\ - Note whether it needs to be installed via ComfyUI Manager
Step 4 - Extract model references
Scan node inputs for model filename references (.safetensors, .ckpt, .pt, .onnx, .bin).
Map each to the correct models subfolder:
| Filename pattern / node type | Destination |
|---|---|
| Checkpoint (SD, SDXL, Flux) | models/checkpoints/ |
| LoRA | models/loras/ |
| VAE | models/vae/ |
| ControlNet | models/controlnet/ |
| Upscaler | models/upscale_models/ |
| CLIP / text encoder | models/text_encoders/ or models/clip/ |
| UNET / diffusion model | models/diffusion_models/ or models/unet/ |
| Embedding | models/embeddings/ |
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.

comfyui-workflow-analysis is a skill published in the GitHub repository sideshowroberto/vfx-agent-toolkit (16 stars, last pushed 22d ago), licensed MIT. It adds 57 tokens to every session and 825 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-02.
