comfyui-agent-kit

The signature ComfyUI skill for AI coding agents: Claude Code, Codex, Gemini CLI, and Qwen Code.

By AI VFX NEWS.

Make your AI coding agent drive a local ComfyUI at full power, generate images, video, and audio, build and run workflows, and show the graph live in your own ComfyUI canvas, then hand the whole setup to someone else with one command.

This is the portable, machine-independent, multi-agent version of a working ComfyUI setup. One shared core (the knowledge + the MCP driver) plus a thin adapter per agent. Clone it, run the installer, and each of your agents gets the same stack, wired to your hardware. GLM (z.ai) run through Claude Code is covered by the claude adapter. See docs/AGENTS.md for how each agent connects.

What it can do

• Drive ComfyUI from four agents (Claude Code, Codex, Gemini CLI, Qwen Code) off one shared core. GLM via Claude Code is covered too. (docs/AGENTS.md)
• ~90-tool MCP driver. The agent operates ComfyUI directly: generate, build / edit / validate graphs, queue, download models, manage VRAM, read logs, diagnose.
• Per-model "mega-brain": 65 prompt recipes distilled from official sources (image, video, audio, 3D); the agent auto-pulls the right recipe when you name a model, so it prompts each one in its own dialect.
• Knows where each model runs: a full index of all 147 library models (recipe / utility / template-only), local vs API.
• Hardware-aware model selection: detects your VRAM, RAM, and free disk, then recommends the variant that fits (fp8 / offload / multi-GPU / quant) and refuses a download that won't fit, before wasting the bandwidth.
• 18 enhancement and utility tools: upscale / restore (Real-ESRGAN, SUPIR, SeedVR2), frame interpolation (FILM, RIFE), segmentation / depth / pose (SAM3, BiRefNet, Depth Anything), plus restoration chains.
• 534-template library as the source of truth, plus fetch any shared workflow by hash and a model shootout (run a prompt through many models small, pick the winner, then scale up).
• Assembles new workflows from parts: decomposes a task into stages, mixes templates and blueprint subgraphs, and wires the nodes correctly (output-to-input by type, with converters where needed), validated against /object_info before running. Not a preset runner.
• Starts ComfyUI for you: when the server is down, the agent launches it headless in the background and generates (no need to open the app first); to peek, you open http://127.0.0.1:8188 in a browser. For an unattended pipeline the start policy is configurable per project (env vars or a .comfyui-agent.json), so it never blocks on a prompt.
• GUI bridge + persistence: the agent writes graphs into your ComfyUI canvas, and SAVES every workflow it builds or runs to ComfyUI's workflows folder, so you can open it later from the Workflows sidebar (an API generation alone leaves no trace on the canvas).
• Stays current on its own: check_updates.py diffs the template repo and reads the blog RSS; an optional weekly task adds recipes for new models and pushes them. (docs/UPDATING.md)
• Portable and idempotent: one installer, auto-detects your agents, re-runnable. MIT, no vendored third-party code (everything heavy is fetched at install).

The four-layer stack

Plus a GUI bridge: the agent writes graphs to <ComfyUI>/user/default/workflows/, you open them in the built-in Workflows sidebar and tweak them. No extra "agent panel" node required.

See docs/LAYERS.md for each layer, and docs/AGENTS.md for the per-agent matrix.

The template library is the source of truth

The kit clones the official Comfy-Org/workflow_templates and builds a compact lookup index so the agent can match any request to the right template. 534 templates span every task, image, video, 3D, audio, utilities:

It knows every model's dialect

Each generative model rewards a different prompt approach: SDXL wants comma tags, FLUX wants natural-language sentences, video models want camera and motion direction, audio models want genre/tempo/instruments, and negative-prompt support varies wildly. The kit ships MODELS.md, a per-model prompting reference distilled from official sources (each maker's docs and model cards, docs.comfy.org, and the per-model templates from the anthropic-claude node). When you name a model in a request or a workflow, the agent reads that model's entry first and prompts it correctly.

Covered today (65 models with recipes): FLUX.1/.2 + Kontext, Z-Image, Qwen-Image/Edit, SDXL, SD1.5/3.5, HiDream, Ideogram, Nano Banana Pro/2, Seedream, Recraft, GPT-Image, Grok, Reve, Kandinsky, BRIA, OmniGen, Chroma, Krea, ERNIE-Image, FireRed/LongCat/ChronoEdit (edit), Capybara, Bernini-R, Anima, NewBie, PixelDiT, Ovis-Image, Lens, Quiver, Wan 2.1-2.7, LTX-2.3/2 Pro, Hunyuan Video, SVD, Kling, Veo, Sora, Seedance, Luma, Runway, MiniMax, PixVerse, Vidu, Pika, HappyHorse, HuMo, SCAIL-2, Stable Audio, ACE-Step, ElevenLabs, ChatterBox, Sonilo, Hunyuan3D, Tripo, Rodin, Meshy. Plus a separate Enhancement and utility section (not prompt-driven, settings not prompts): upscalers and restorers (Real-ESRGAN, SUPIR, SeedVR2, FlashVSR, Topaz, Magnific), frame interpolation (FILM, RIFE), conditioning helpers (SAM3, BiRefNet, Depth Anything, DWPose, MoGe, IP-Adapter, LivePortrait, Mediapipe), and video object removal (VOID). Anything else falls back to the template library.

Full model index: every model in the library and exactly what the kit has for it (recipe / utility / template-only): docs/MODEL_INDEX.md.

Coverage table: every model and whether a prompt recipe is ready

✅ recipe = a dedicated, up-to-date prompting guide in MODELS.md. 🔧 tool = an enhancement/utility note (settings, not prompts). Updated: 2026-06-19 23:08.

One table, columns aligned to the widest row (the video models).

Niche models still without a recipe (very new, thin docs) run from their template and borrow the closest family's approach; see docs/MODEL_INDEX.md for the full per-variant breakdown.

Prerequisites

• One or more agent CLIs on PATH: Claude Code (claude), Codex (codex), Gemini CLI (gemini), Qwen Code (qwen)
• Node.js (node + npm)
• git, Python 3
• A local ComfyUI install (Desktop or source), comfy.org

Install

Windows (PowerShell):

git clone https://github.com/SlavaSexton/comfyui-agent-kit.git
cd comfyui-agent-kit
./install.ps1 -ComfyUIPath "E:\path\to\ComfyUI"   # installs for every agent CLI found on PATH

Linux / macOS:

git clone https://github.com/SlavaSexton/comfyui-agent-kit.git
cd comfyui-agent-kit
./install.sh --comfyui-path /path/to/ComfyUI       # installs for every agent CLI found on PATH

The installer runs the shared machine setup once (MCP package, templates, in-graph nodes), then auto-detects which of claude / codex / gemini / qwen are installed and wires each one. It is idempotent, re-run it any time. Limit the targets with -Agents claude,gemini / --agents claude,gemini. Flags: -SkipTemplates / --skip-templates (skip the ~900MB template clone), -SkipNodes / --skip-nodes. Per-agent details and the GLM note are in docs/AGENTS.md.

First run on a new machine

After install, start ComfyUI, then in an agent session tell it to run the bootstrap once (docs/BOOTSTRAP.md): it detects your GPUs, VRAM, RAM, free disk, paths, and installed models via the MCP health_check, fills the machine-specific block in the skill, and does a smoke-test generation. After that, just ask for media. On Claude/Codex the skill auto-activates on ComfyUI keywords; on Gemini/Qwen the knowledge is loaded as the extension's context.

Optional: in-graph LLM key

Only needed if you want a workflow to enrich prompts without the agent in the loop (e.g. an unattended pipeline):

setx CLAUDE_API_KEY "sk-ant-..."   # then restart ComfyUI

See docs/NODES.md. When you are driving, the agent writes prompts directly, better and free.

What is and isn't in this repo

In the repo (original work, MIT): the skill, the client, the installer, the index generator, the docs, the generated visuals. Fetched at install time from their own sources (not redistributed here): the comfyui-mcp package, the node-building skills, the workflow templates, and the in-graph Claude nodes.
