GALIAIS-Nodes Prompt Viewer

Prompt chains are great until they turn into a black box. By the time your prompt has passed through a composer, a conflict pruner, and a quality gate, the string that actually reaches the sampler is... what, exactly? The Prompt Viewer is the inspection node at the end of the line: feed it the final positive, negative, and the pack's metadata JSON, and it renders all of it in a readable UI panel so you can see what the pipeline really produced before you burn a render on it.

The inputs

• 正面提示词 / 负面提示词 - your final strings (Chinese labels again: 正面 is positive, 负面 is negative).
• 元信息JSON - the metadata blob most GALIAIS nodes emit from their ...JSON outputs. Paste it or wire it in and the viewer shows the diagnostics alongside the text.
• 标题 - the panel's title. Defaults to "GALIAIS-Nodes Prompt Output"; rename it if you have several viewers in one graph.
• 透传输出 - passthrough, on by default.

The one setting that bites

透传输出 (passthrough). On by default, it echoes all three inputs back out its outputs - so you can put the viewer in the middle of a chain to peek without breaking the flow. Turn it off and the outputs go empty. That's the trap: it's an OUTPUT_NODE, meant to sit at the end of a wire, and if you disable passthrough mid-graph you've just cut your own prompt. Leave it on unless you specifically want to null the stream.

Where it belongs

This is the node you reach for when something downstream looks wrong and you suspect the prompt. The standard GALIAIS flow ends with Prompt Quality Gate → Prompt Viewer: the gate says whether the prompt is healthy, the viewer shows you the exact text the gate judged and what the sampler is about to consume. If the render came out with a stray tag you didn't intend, the answer is almost always visible here - duplicates that survived dedupe, an artist tag that shouldn't be there, a section that got disabled upstream. Because it also passes everything through, you can drop it inline anywhere in the chain as a debug readout and leave it there.

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/GALIAIS/GALIAIS-Nodes.git

Restart ComfyUI. No dependencies, no DB, nothing to configure - it's a display node. The only "issue" you'll hit is the Chinese labels on a first run, and the passthrough toggle described above. Both are five-second fixes.
