separate

Verify that a watermark-removal or "humanizer" step actually removed a statistical text watermark, by measuring a sample whose key the user holds. Use after any tool, script or service claims to have cleaned a text, or when the user asks whether such a tool works, which one to trust, or how to test one. Reports a detector score against fixed thresholds plus what the run cost in meaning, facts, verbatim overlap and length. This skill only measures and never removes a mark.

When to use

• A "watermark remover", "AI humanizer" or "detector bypass" tool claims it cleaned a text, and the claim needs checking before anyone repeats it.
• Someone is about to pay for such a tool and wants evidence instead of a landing page.
• Several such tools have to be compared on one ruler, with numbers another person can reproduce.
• A rewriting step sits inside a pipeline, and someone needs to know what it costs in meaning, facts and length.
• The user asks how these tools can be tested at all, or why a "99% undetectable" promise cannot be verified from outside.

When not to use

• removing a watermark
• claiming anything about a specific vendor's watermark
