This repository provides a Claude Skill for detecting and removing 'AI slop' from Japanese prose. It consists of a set of guidelines (SKILL.md) and reference files that enumerate problematic phrases, structural patterns, and examples of AI-generated text versus human-revised versions. The skill focuses on restoring human agency, stance, specificity, rhythm, and reduction in LLM-generated Japanese text. It is designed to be used during drafting, editing, or review stages to improve the authenticity of AI-assisted writing.
