Prompt Store B (CCN)

Prompt Store B is the persistent version of Prompt Builder B - same quality/style/mood/motion/general vocabulary, but with the session-memory behavior of the plain Prompt Store. Type something into a section, and it's remembered under the store's name until ComfyUI restarts or you clear it.

The one genuinely clever detail: it can share a store_name with a plain Prompt Store without colliding, because the two use different internal keys. PromptStore writes metadata/features/scene/details/feedback; PromptStoreB writes quality/style/mood/motion/general. So you can have one store_name holding, say, "default" that accumulates both a scene block and a mood block from two different nodes. That's unusually well-thought-out for a utility like this, and it's the reason you don't need to invent a separate store name for every variant.

The inputs that matter

• store_name - the key; match it to share storage.
• input_mode - override / merge / append, exactly like its sibling. Empty section = keep the stored value, which is how you avoid clobbering.
• separator - the split used by merge (default , ).
• clear - wipes this store's B-keys.
• prefix_sections / delimiter - the assembly knobs.
• Outputs: the joined prompt plus each of quality, style, mood, motion, general as individual STRINGs.

Install

Same pack, one install:

cd ComfyUI/custom_nodes
git clone https://github.com/valkymaera/ComfyCollectorNodes

then restart, or install via ComfyUI Manager ("ComfyCollectorNodes"). No models, no extra deps.

Where people get burned

The session-scope reality applies here too: stored values survive across workflows but die on restart, and nothing is written to disk. If a mood from last week is showing up in today's output, that's not a bug - that's the feature you forgot about. And because the labels are aimed at "how a shot feels" rather than "what's in it," it's easy to overload general with everything that doesn't fit elsewhere; that's fine, but remember merge mode will dedupe on the separator, so keep general comma-delimited if you want dedup to work.
