[OLD] Tag Wiki Lookup

Somewhere in every tag-prompting workflow there's a moment where a post makes no sense and you need to know what the tag actually means. Tag Wiki Lookup is the pack's answer: paste a tag, get the wiki description from Danbooru or e621, read it, move on. It's marked [OLD], it's barebones, and the author himself says the output is "probably enough for most people" - which is a fair summary. This is a utility node, not a showpiece.

It's an output node with a small party trick: a Fetch Wiki button on the node itself that runs without queuing, showing the text in a read-only textbox. So you don't have to push your whole workflow through the sampler just to check a tag - a genuinely nice touch for a node this simple.

How it works

The node normalizes whatever you type - spaces to underscores, backslashes stripped, extra underscores collapsed - then asks the selected board's wiki API. Danbooru and e621/e6ai/e926 are the two options in the booru dropdown, each using its own endpoint and parameter shape. One honest limitation to know before you rely on it: it only handles the first tag. Feed it a comma-separated list and everything after the first comma is ignored. The tooltip says so, and it's worth taking seriously.

The extended_info dropdown (yes / no / only_extended) controls trimming. Wiki pages are long and full of formatting, so with no (the default) it cuts the description at the first subheading - that's the practical "what is this tag" answer. yes returns the whole body, and only_extended gives you just the cut-off tail. It's crude, but it works.

Inputs and output

• tags - the tag to look up (first tag wins).
• booru - danbooru or e621, e6ai, e926.
• extended_info - how much of the wiki body to return.

The single output is a STRING with the wiki text. Since it's an output node you can also wire it anywhere a string is expected - into a text display, a file writer, whatever - but the in-node textbox is the intended use.

Install

Same pack, same routine:

cd ComfyUI/custom_nodes
git clone https://github.com/DraconicDragon/ComfyUI_e621_booru_toolkit

restart ComfyUI (or search the pack in ComfyUI Manager). Dependencies are the light set - requests, pillow, curl_cffi - and the wiki fetch itself rides on a small server endpoint the pack registers.

Gotchas

The output is raw wiki body text, so expect markdown and booru formatting noise rather than clean prose - the trimming is the only cleanup it does. The [OLD] tag means the author treats it as legacy, so don't lean on it inside an automation loop that queues hundreds of lookups; the boards rate-limit. For a one-off "what does this tag mean," it does the job without a browser tab, and that's about all it promises.
