gbresil/watermarks-remover ? reverse-engineered prompt

Build me a privacy first tool that cleans AI watermark traces from content I own.

I want it to work on plain text and on common files like images, documents, PDFs, spreadsheets, slides, ebooks, and audio or video metadata. It should detect and remove things like invisible Unicode junk, odd spacing, bidi characters, and embedded provenance or metadata marks, then give me a clean version I can save or download.

Make it run locally, with a simple service I can call over HTTP, and a lightweight agent skill that can use it without needing any extra setup on the host. It should also be able to check files after edits and either warn me or clean them automatically. If you need to look up current docs online for any file formats or metadata details, go ahead.

Please keep it privacy focused, easy to install, and make sure it only works on content I own.
