⭐ NZ工作流助手（内测版）

You found a node with no inputs, no widgets, and no description, named after a "workflow assistant" that apparently does nothing. That's not a bug - NZ_Base is the pack's canary. It exists so you (and the plugin itself) have a one-glance answer to the question "did this thing actually load?"

The node comes from ComfyUI-WorkflowManager-beta (repo title "NZ工作流助手" - NZ Workflow Assistant), a small, Chinese-authored pack that's positioned as a beta of a bigger paid/full tool. The README is one paragraph: "This is a beta version, but better than ComfyUI official function," plus links to a Feishu and a Notion page where the "full version" lives. In other words, the GitHub release is the preview. The actual features - a workflow sidebar, file browser, notes, custom icons, a floating manager - ship in the pack's web UI (the web/ directory), not in the two graph nodes. NZ_Base is the graph-side handshake for all of that.

What it actually does

Open the source and it's embarrassingly simple: NZ_Base has zero required and zero optional inputs, and its run() returns one hardcoded string: ⭐ NZ插件已激活 ("⭐ NZ plugin activated") as its single STRING output. That's the whole mechanism. It's a registration token with a pulse - ComfyUI only shows you the node in the "NZ Workflow" category if the Python module imported cleanly at startup, so seeing it on the canvas is proof the plugin's backend loaded. The string it emits is just its heartbeat.

That's it. Don't expect it to manage workflows, save anything, or touch your files. If the pack's sidebar UI isn't showing up after install, this node won't fix it - it only tells you whether the plugin registered.

Inputs and outputs

There's one output and nothing else to set:

Output STRING - always ⭐ NZ插件已激活 (in Chinese, "NZ plugin activated"). You can wire it into a display/string node if you want visible proof in a saved workflow, but its real job is existing.

Installing it

Standard custom-node install. Via ComfyUI Manager, search for "NZ workflow manager - beta" (the registry display name from the pack's pyproject.toml) or "WorkflowManager" and hit Install. Or clone it by hand:

cd ComfyUI/custom_nodes
git clone https://github.com/K-O-N-B/ComfyUI-WorkflowManager-beta

Then restart ComfyUI. There are no model files to download - dependencies are light (psutil, py-cpuinfo, pynvml) and it declares Python 3.10–3.13 support. After restart, look for the "NZ Workflow" category in the node menu.

Gotchas worth knowing

The install succeeded if this node exists. Missing NZ_Base means the pack failed to import - check the ComfyUI console log for the "NZ" logger lines rather than reinstalling blindly.
It's a beta, deliberately thin. The README points at the Feishu/Notion docs for the full version; what you get on GitHub is the preview. Feature promises ("better than ComfyUI official function") are marketing, not a spec.
Its sibling node can read and write arbitrary paths. NZ_Workflow_Manager and the pack's HTTP/WebSocket endpoints have full filesystem access to whatever the ComfyUI process can reach, with no sandboxing. Fine on your own machine; a bad idea if you've exposed your ComfyUI port to the internet. That "please secure your ComfyUI instance" PSA from the community applies double here.

Honestly, you'll keep this node around for one reason: it's the cheapest possible smoke test that a beta pack loaded before you go hunting for its sidebar. If you're here because the node itself looks useless - it is, on purpose. The work is elsewhere in the pack.
