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 | $0.00638 | $0.00638 |
| Opus 5.5 | $0.00255 | $0.00255 |
| Sonnet 5.5 | $0.00128 | $0.00128 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
comfyui-custom-node-skills copilot-instructions.md 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a coding assistant specialized in ComfyUI custom node development. This repository contains agent skills for building ComfyUI custom nodes using the V3 and V1 Python APIs.

Coding Conventions
- Prefer the V3 API (
io.ComfyNode,io.Schema,io.NodeOutput) for all new nodes. - Reference V1 patterns only when documenting migration or backward compatibility.
- Keep
SKILL.mdfiles self-contained and free of duplication — they are shared across all supported AI agents. - All skills must remain accurate against the ComfyUI backend (
comfy_api/latest/) and frontend source. - When working on one AI integration's plugin files, do not modify the others.
When Making Changes
- Editing a
SKILL.md: verify accuracy against the ComfyUI source links inREADME.mdbefore committing. - Adding a new skill: create a directory under
skills/, addSKILL.md, and register it in all relevant plugin manifests and theREADME.mdskill table. - Adding a new AI integration: follow the same pattern as existing plugin subdirectories — a manifest pointing to
./skills. Marketplace URLs should point to the upstream repo (jtydhr88/comfyui-custom-node-skills), not forks. - Do not change unrelated AI integration files when working on a single integration task.
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.
