What problem does it solve? Chinese product documents often read like machine output: padded sentences, buzzwords like 赋能 and 闭环, decorative bolding, and "not X but Y" rhetorical patterns that force readers to decode meaning. This Skill detects and fixes those expression-level problems so documents read plainly, without touching facts or structure. ## Core Features & Use Cases - Three working modes: annotate problems only (detect), produce a full rewrite with a change summary (rewrite, default), or edit the file in place (edit). - Four-category pattern scan: checks verbosity, AI-flavored phrasing, jargon, and vague writing against a graded pattern catalog in references/patterns.md, with P0/P1/P2 severity levels. - Optional independent cold read: when a codex environment exists, runs a separate-context critique pass to catch residual AI tone and unintended meaning changes. - Use Case: A PM pastes a PRD section full of "拉通 / 抓手 / 不是简单的X而是Y" phrasing and asks to 说人话; the Skill returns a plain-language rewrite with a list of what changed and a second self-review pass. ## Quick Start Paste a paragraph of Chinese product text or give a file path and ask to polish it and remove the AI tone, optionally specifying annotate, rewrite, or edit mode.
