Included Skills2

humanizerskills/humanizer/SKILL.md

Rewrite AI-sounding text so it reads like the writer without changing what it says. Use when editing or reviewing prose for AI tells: not-X-but-Y contrasts, one-line closers, staged openers, forced triads, dashes everywhere, inflated claims, sales language, stock AI words, bold labels, or filler. Based on Wikipedia's "Signs of AI writing."

natural-japaneseskills/natural-japanese/SKILL.md

仕事の日本語文書を読みやすくわかりやすく書く・直すためのスキル。議事録(文字起こしからの議事録化を含む)、調査レポート・分析レポート、社内ガイド・マニュアル、リサーチメモ・ディスカッションペーパー・企画書・提案書・報告書・メール、スライド構成案といったビジネス文書の作成・校正、「結論から書いて」「論旨を明確に」「見出しを端的に」「専門用語をわかりやすく説明して」といった指示のいずれでも使用する。AI臭さの除去(「AIっぽい」「AI臭い」「機械翻訳っぽい」「不自然」「もっと自然な日本語に」「機械っぽい」「人間っぽくして」「単調」「〜することができる、と言えるだろう、のような言い回し」といった直接・間接・口語の指摘、AIで書いたと言われた/疑われた)、読みにくい・わかりにくい文章の改善依頼(語順がおかしい、一文が長い、何が言いたいか分からない、読点の位置がおかしい等)、note記事やブログ記事・エッセイの新規執筆(任意のテーマをゼロから書く・書き起こす依頼を含む)、既存文章のリライト・推敲、AI臭さの診断・採点(「この文章AIが書いた?」「AI臭さをスコアで出して」「どれくらいAIっぽいか判定して」という書き換えを伴わない依頼)、自分の文体を学ばせたい・プロファイル化したいという要望(過去の文章を読ませて自分らしく書いてほしいという依頼も含む)にも対応する。禁止語の除去、リズムの単調さ・段落構造の均質さ・英語統語の直訳調に加え、語順・読点・一文一義・主語述語の距離といった読みやすさの原則にも対応する。技術文書の章構成やMarkdownフォーマットの整形自体(一文一行化・引用ブロック・脚注記法など)は対象外——それは別スキルの領域であり、本スキルは文章の自然さ・読みやすさ・わかりやすさに特化する。
