Good to know
What is official and what is not?
No. This is an independent, unofficial browser companion. The official skill, source, releases, and support live in the blader/humanizer GitHub repository.
No. It automates 12 literal text signals. The official skill reviews 35 broader patterns, many of which need context and human judgment.
Yes. Use the official repository's source ZIP, especially for Claude Desktop. This site no longer generates a smaller substitute skill.
