Generate a wide range of one-line hooks from the author's words and the draft: article titles, README taglines, subtitles, announcement lines. Use when asking for title or tagline candidates (タイトル案).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Headline Craft — 開かせる一行を作る 読者は本文を読む前にタイトルで開くかどうかを決める。このスキルは候補を広く作るところまでを担う。 選ぶのは著者なので、候補は数が多く、文の形がばらけているほど役に立つ。 **役割分担（defer 宣言）**: - 題の規範と著者の題の形 → project の Title Conventions が正本（`~/MyAI_Lab/zenn-content` では `writing-ecosystem` 内）。定義が無い project では、下の「誠実さの照合」だけを規範にする - platform 文字数・記法 → 各 project の publication channel contract。実値はここに書かない - 公開記事候補の点検 → `title-reviewer` agent（`~/MyAI_Lab/zenn-content` 常駐）。本 skill 自身の候補を自己採点しない - topics / emoji → platform を所有する project-local skill ## 実証知見（技法の根拠） - **ポジティブな飾り言葉は CTR を下げる**: Upworthy の約 10.5 万 headline 変種の分析（Robertson et al. 2023, Nature Human Behaviour）で、ポジティブ語の追加は消費率を下げた。同研究はネガティブ語による CTR 上昇も示した - **具体性には上限がある**: Upworthy の見出し A/B テスト 8,977 件の再分析（Aubin Le Quéré & Matias 2025, Scientific Reports）で、具体性とクリック率の関係は山なりだった。具体性を上げて得をする見出しは 8.7%、上げるとクリック率が有意に下がる見出しは 50.9%。一般向けソーシャルニュースの結果で、検索流入は含まない（as-of 2026-09-29） - **好奇心ギャップは情報の欠落**: Loewenstein の information gap 理論。知っていることと知りたいことの差が開かせる。ただし**本文が必ずギャップを埋めること** — 埋めない好奇心ギャップがクリックベイトの定義 - **日本語圏の参考値**: Qiita 全記事分析でバズ記事はタイトル 20–36 字に集中。各 platform の上限より短い方に最適帯がある …

How to install
mdr add shimo4228/claude-harness/headline-craft@sha256:e8a7725a7be94130The line at the top of this page pins the label git:20261008.b63e5f1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
