TT Context Passthrough

TT Context Passthrough takes a TT_CONTEXT in and hands the exact same context back out. That's it. No transformation, no new state, no outputs beyond the context itself. On paper it's the most useless node in the pack. In practice it's a reroute node for a single custom wire type, and once you've built a context workflow that needs routing, you'll get why it exists.

The problem it solves is a real one: ComfyUI's built-in reroute nodes don't always play nicely with custom socket types like TT_CONTEXT, and when your context wire needs to bend around another branch of the graph, you sometimes want a clean labeled pass-through point rather than a wire dragged across the whole canvas. This node is that point. Its only job is to exist in the middle of a context chain so you can organize the graph without changing the data.

How to use it

Wire a TT_CONTEXT in, wire CONTEXT out to the next context node. That's the whole interaction. It's the context-wire equivalent of a numbered comment or a label: it makes the flow legible, breaks a long chain into visually distinct segments, and gives you an anchor point if you ever need to intercept the chain later (by replacing it with a setter node like TT Context Set Latent or TT Context Set Image).

It's also genuinely useful as a debugging checkpoint. Since it forwards state untouched, you can place one at a point in the chain, and if a node downstream errors, you know the context was still intact when it left this node - narrowing the problem to whatever sits between here and the failure.

Caveats

The usual TenserTensor context rules apply hard: TT_CONTEXT is a proprietary socket that only connects to other TenserTensor context nodes, so this node is meaningless outside a context workflow. It's also a legacy V1 node - the pack migrated to ComfyUI's API V3 and moved the V1 context nodes to Deprecated/, with removal planned for a future major release.

The honest take: if your graph doesn't have context wires yet, you don't need this node. If it does, it's a cheap organizational tool - like a bookmark for your data flow. Just don't expect it to ever do anything. The day you expect it to do something is the day it stops being the right node.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/tenser-tensor/ComfyUI-TenserTensor

or ComfyUI Manager → search "TenserTensor" → install → restart. The pack's dependencies are gguf and kornia, which Manager installs automatically.
