Vale AI Tells Flags Patterns in AI-Written Prose

Summary

Vale AI Tells is an open-source Vale style package for spotting recurring patterns in AI-written and formulaic prose. It runs locally, flags 17 types of signals, and leaves rewriting to the author. The rules support Markdown, HTML, and plain text, can be installed through Vale, and can also be used as a Claude Code skill. The project presents itself as a rule floor rather than a detector, with examples and a small benchmark for evaluating recall and false positives.
