I think this depends on the exact disclosure requirements of each platform. Steam, for example, does not require disclosure for any background tools. If you have a specific platform in mind, I'd be happy to read through their disclosure requirements and give you a more precise response.

Thank you. Itch has roughly the same policy as Steam (without the distinction between pre- and live-generated AI content) and requires disclosure when a project includes or generates AI-created content in the final product, not for AI used as development aid. You can read it here: https://itch.io/docs/creators/quality-guidelines. Since my plugin does not produce content (Itch specifically identifies "text, images, music"), it does not require disclosure.
