Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00041 | $0.04179 |
| Opus 5.5 | $0.00016 | $0.01672 |
| Sonnet 5.5 | $0.00008 | $0.00836 |
| Haiku 4.5 | $0.00004 | $0.00418 |
Grade A, and why
comfyui-gateway scanned grade A with 1 finding 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.

ComfyUI Gateway
Overview
REST API gateway for ComfyUI servers. Workflow management, job queuing, webhooks, caching, auth, rate limiting, and image delivery (URL + base64).
When to Use This Skill
- When the user mentions "comfyui" or related topics
- When the user mentions "comfy ui" or related topics
- When the user mentions "stable diffusion api gateway" or related topics
- When the user mentions "gateway comfyui" or related topics
- When the user mentions "api gateway imagens" or related topics
- When the user mentions "queue imagens" or related topics
Do Not Use This Skill When
- The task is unrelated to comfyui gateway
- A simpler, more specific tool can handle the request
- The user needs general-purpose assistance without domain expertise
How It Works
A production-grade REST API gateway that transforms any ComfyUI server into a universal, secure, and scalable service. Supports workflow templates with placeholders, job queuing with priorities, webhook callbacks, result caching, and multiple storage backends.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-gateway is a skill published in the GitHub repository hainamchung/agent-assistant (54 stars, last pushed 5mo ago), licensed MIT. It adds 41 tokens to every session and 4,179 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
