In plain words
What is it for?
Use it to create a skill for a named ComfyUI node pack, or to request the pack choice when no source is provided.
Why use it?
It saves you from manually turning a node pack's documentation into a format Claude Code can use. It also tells you where the generated skill was saved and whether Claude Code may need restarting.

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

node-skill 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 1mo 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.

What it actually says

/comfy-skill — Generate a Node Pack Skill

The user wants to generate a Claude Code skill file for a ComfyUI custom node pack.

Instructions

  1. Parse the argument. The argument is: $ARGUMENTS

    • A ComfyUI Registry ID (e.g., comfyui-impact-pack)
    • A GitHub repository URL (e.g., https://github.com/ltdrdata/ComfyUI-Impact-Pack)
    • Nothing — ask the user which node pack they want to generate a skill for

  2. Generate the skill. Use the generate_node_skill tool with:

    • source: the registry ID or GitHub URL
    • install_in: save to skills/<pack-name>/ inside the plugin directory

  3. Report the result. Tell the user:

    • Where the skill file was saved
    • A brief summary of what nodes are covered
    • That they may need to restart Claude Code for the skill to take effect

Example

User: /comfy-skill comfyui-impact-pack

Steps:

  • Call generate_node_skill with source "comfyui-impact-pack" and install_in set to the skills directory
  • Show the user where the file was saved and what it covers

Notes

  • The generated skill includes node class types, input/output specs, and usage examples
  • Skills are saved as SKILL.md files in subdirectories under the plugin's skills/ folder
  • If the node pack isn't found in the registry, suggest the user provide a GitHub URL instead
  • If nodes from the pack are installed locally, the skill will include live /object_info data

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.
