What it is

A skill file for Claude Code, Codex, and other skill-capable agents that finds common tells of machine-generated text and rewrites them while keeping the meaning intact. It checks 26 patterns drawn from Wikipedia's guide to spotting AI writing, such as forced triads, one-line closers, and inflated significance, and it can match a voice sample you provide. Writers and developers use it to clean up drafts, docs, and posts, either pasted in or edited in place in files, without the tool inventing facts.
