Load Boolean

Nothing fancy here - this is a true/false switch you can wire into a graph, which sounds trivial until you notice how many nodes in comfyui_LLM_party expect a boolean on an input rather than a hardcoded widget value. is_enable shows up constantly across this pack's tool and knowledge-base nodes as a way to toggle a piece of the graph on or off without deleting it, and if you want that toggle controlled by something upstream - another node's logic, a shared value reused in three places - you need a node that actually outputs a BOOLEAN, not just a checkbox baked into some other node's UI.

That's what Load Boolean is. It's ComfyUI's equivalent of a primitive constant, scoped to a single true/false value, packaged as its own node so it can sit anywhere on the graph and feed multiple downstream inputs from one place.

The one field. text is the input's actual name in the schema, which is a little odd for something that's really a boolean toggle - most likely a naming convention shared across this pack's family of "load a constant" nodes (this one, Load Integer, and others) so they're easy to swap for each other via ComfyUI's right-click "convert" options. It defaults to true. The output is bool, typed BOOLEAN, and that's what you wire downstream into whatever's expecting a true/false - most commonly another node's is_enable input somewhere else in this pack.

One detail worth knowing: this node is flagged as an output node in its schema, meaning it can also act as a terminal on the graph and display its own value directly, not just pass it along silently to something else. Handy if you're debugging a larger agent workflow and want to confirm at a glance what a shared boolean is actually set to without tracing the wire all the way to wherever it's consumed.

Installing it. Load Boolean comes bundled with the whole comfyui_LLM_party pack - there's no separate install step. Get it through ComfyUI Manager (search "comfyui_LLM_party" and install) or manually via cd ComfyUI/custom_nodes && git clone https://github.com/heshengtao/comfyui_LLM_party, then run pip install -r requirements.txt from inside the project folder using your ComfyUI Python environment, and restart ComfyUI. It's a pure utility node with zero external dependencies of its own - no API key, no model file, nothing to misconfigure. If it's missing from your node list after install, the cause is virtually always the pack's much larger dependency footprint failing to import elsewhere and taking the whole node set down with it; check the ComfyUI startup console for the actual error rather than treating this node as the culprit.
