comfyui

A guide for running ComfyUI, a visual system for connecting image, video, audio, and 3D generation steps into workflows. It covers installation, models, nodes, workflow files, and local or cloud execution.

In plain words
What is it for?
Use it to install and launch ComfyUI, inspect workflows, inject settings, run generation jobs through its API, and decide whether to use local hardware or Comfy Cloud.
Why use it?
It helps translate a saved workflow into the format ComfyUI can run and checks hardware, memory, cloud limits, and common workflow problems.

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 B, and why

comfyui scanned grade B with 3 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 2d ago.

The scan reads SKILL.md. This mod also ships 17 executable files (scripts/_common.py, scripts/auto_fix_deps.py, scripts/check_deps.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -X POST http://127.0.0.1:8188/queue -d '{"clear": true}' # cancel pending

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

curl -s http://127.0.0.1:8188/queue | python3 -m json.tool

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 613 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ComfyUI

Generate images, video, audio, and 3D content through ComfyUI using the official comfy-cli for setup/lifecycle and direct REST/WebSocket API for workflow execution.

What's in this skill

Reference docs (references/):

  • official-cli.md — every comfy ... command, with flags
  • rest-api.md — REST + WebSocket endpoints (local + cloud), payload schemas
  • workflow-format.md — API-format JSON, common node types, param mapping
  • template-integrity.md — converting comfyui-workflow-templates from editor format to API format: Reroute bypass, dotted dynamic-input keys (values.a, resize_type.width), Cloud quirks (302 redirect, 1 concurrent free-tier job, 1080p VRAM ceiling), Discord-compatible ffmpeg stitch. Authored by @purzbeats. Load this whenever you're starting from an official template.

Scripts (scripts/):

Script Purpose
_common.py Shared HTTP, cloud routing, node catalogs (don't run directly)
hardware_check.py Probe GPU/VRAM/disk → recommend local vs Comfy Cloud
comfyui_setup.sh Hardware check + comfy-cli + ComfyUI install + launch + verify
extract_schema.py Read a workflow → list controllable params + model deps
check_deps.py Check workflow against running server → list missing nodes/models
auto_fix_deps.py Run check_deps then comfy node install / comfy model download
run_workflow.py Inject params, submit, monitor, download outputs (HTTP or WS)
run_batch.py Submit a workflow N times with sweeps, parallel up to your tier
ws_monitor.py Real-time WebSocket viewer for executing jobs (live progress)
health_check.py Verification checklist runner — comfy-cli + server + models + smoke test
fetch_logs.py Pull traceback / status messages for a given prompt_id

Example workflows (workflows/): SD 1.5, SDXL, Flux Dev, SDXL img2img, SDXL inpaint, ESRGAN upscale, AnimateDiff video, Wan T2V. See workflows/README.md.

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 is a skill published in the GitHub repository StarryCod/cogitum (11 stars, last pushed 3mo ago), licensed MIT. It adds 46 tokens to every session and 6,342 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 3 findings (sends data to an external url, downloads and executes remote code, makes network calls). It is 98% identical to comfyui, differing in 50 lines, and is treated as a copy.
