Use to audit and clean text so it reads human-written, not machine-generated. Covers what to look for (guided by Wikipedia's "Signs of AI writing"), how to scan for the markers, how to fix them without flattening a good voice, and how to verify. Works on any prose in any project (course text, docs, articles, READMEs). Trigger phrases: "de-AI this", "remove AI tells", "does this sound like AI", "AI speak", "de-slop", "make this read human", "check for signs of AI writing".
