watermarks-remover
node://watermarks
watermarks-remover is a third-party project I cloned and validated for studying AI provenance marks: invisible Unicode, statistical token watermarks, and C2PA / EXIF / container metadata across common document and image formats.
I run it as a Claude Code skill against my own output, to test detection and to understand what those marks actually look like. That is a defensive lab use, not a service for stripping disclosure off other people's work.
The test suite passes locally. Full C2PA tooling and statistical scoring still need optional extras installed. Upstream: guillaumemeyer/watermarks-remover on GitHub.
