Rewrites AI-generated or overly formal text into clear, human-sounding plain language by removing common robotic patterns.

The Not-AI skill is designed to strip away the clinical, repetitive, and hyperbolic traits common in AI-generated content. It systematically identifies 'puffery' words, repetitive sentence structures, and characteristic punctuation marks—like em dashes and curly quotes—that signal machine-written text.
