📚 OVERTLI Prompt Library

You know how prompt management usually works in ComfyUI? A text file you keep open in another window, or a browser tab full of saved prompts you copy-paste from. GZ_PromptLibraryNode is the Overtli Studio Suite's answer to that: a small CRUD store that lives on your canvas, saves prompts to disk, and hands them back as a STRING you can wire straight into any text input - including the pack's own enhancer nodes.

What it does

It's an action node. The action dropdown picks the operation:

• save_prompt - stores prompt_text under a prompt_name, optionally with a category, tags_csv and notes.
• load_prompt - pulls a saved entry (choose it from saved_prompt) and emits it.
• view_library - lists what you've got, useful for eyeballing before you load.
• delete_prompt - removes an entry.
• refresh_cache - re-reads the JSON file, which matters if you edit it by hand or other workflows have written to it.

Storage is a JSON file at ComfyUI/user/overtli_prompt_library.json in your ComfyUI user directory - plain, portable, and editable outside the node if you ever need to bulk-import. It's the same shape as the settings file the pack's GZ_ProviderSettings node writes, just for prompts instead of keys.

Inputs worth knowing

• prompt_text and prompt_name - what you're saving and what to call it. prompt_name doubles as the search term on loads.
• saved_prompt - the dropdown of everything in the library. It starts as a single "(none)" option and fills in after a save or refresh, so if the library looks empty, hit refresh_cache or run any action once.
• category, tags_csv, notes - metadata for organizing. category_pick and category_filter let you filter by category, and search_query filters by text.
• sort_mode - order results by most recent, name, most used, category, etc. Loads increment increment_use_on_load (on by default), so most_used sorting actually learns what you reach for.
• allow_overwrite - on by default, meaning saving the same prompt_name twice overwrites instead of erroring. Turn it off if you want save collisions to fail loudly.
• max_items - caps list output (default 100).
• refresh_before_action - re-reads the file before each action, default on; leave it unless you're chasing a performance issue on a huge library.

Output and wiring

One prompt_text STRING output, holding whatever the action produced - the loaded prompt, the saved prompt's text, or the library listing. Chain it into an enhancer's prompt input or straight into a CLIP Text Encode. Because it's a plain string, it plays fine with any node that takes text, not just Overtli ones.

Install and gotchas

Standard pack install: search "Overtli" in ComfyUI Manager, or clone into custom_nodes and pip install -r requirements.txt, then restart. Two habits to build early. First, the dropdown of saved_prompt doesn't watch the file - after editing the JSON by hand or saving from another workflow, run refresh_cache (or set refresh_before_action on) before you expect to see the new entries. Second, this stores text in plain JSON in your user directory; it's local and free, but it's not a team server, so if two people edit the same file you'll get last-writer-wins. For a single machine it's exactly the right size for the job.
