Write AI-facing documents (llms.txt, llms-full.txt, FAQ pages, glossaries) to the llms.txt standard. Use when a document's only reader is an AI system.
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
# llms-txt-writer — AI-Facing Writing Skill AI 検索エンジン（ChatGPT / Perplexity / Gemini）と AI エージェントに引用・参照されることを最適化した文書を書くスキル。静的解析（GEO-SFE）と Answer.AI llms.txt 標準の両方をカバーする。 ## When to Use 以下のいずれかに該当するとき: - `llms.txt` / `llms-full.txt` を新規作成・更新する - FAQ / 用語集など AI 検索引用を狙うドキュメントを書く - 既存の AI-facing 文書の GEO スコアを診断・改善する **使わない場面**: - README / repo のトップページ（`readme-writer` を使う — 証拠スクリプトと、主張をコードとも照らす fresh context の判定器 readme-judge を持つ） - 記事 / エッセイ / ブログポスト等の人間向けコンテンツ（`writing-ecosystem` を使う） - 人間可読性を最優先したいドキュメント --- ## Audience Separation: Human vs AI ドキュメントは **人間 primary** か **AI primary** かで最適化が根本的に異なる。1 ファイルで両立させると、どちらにも中途半端になる。 | 軸 | 人間 primary | AI primary | |----|-------------|------------| | 構造 | 物語的、段落で流れる | Q&A / 定義形式、H2 独立 chunk | | 見出し | 宣言形で簡潔 | 質問形で 20%+ | | エンティティ配置 | 文脈に合わせて自然に | 冒頭 30% に 45%+ 集中（ski-ramp） | | 定義 | 文脈から読み取れる | `X is defined as Y` を明示 | | セクション長 | 論点重要度に比例 | 50-150 語 / 150-450 字に揃える | | 読みやすさ | 最優先 | 犠牲にしてよい | 本 skill は **AI primary の最適化のみ扱う**。 --- ## Answer.AI llms.txt Standard（**v2** — as-of 2026-08-23 に一次ソース確認） [llmstxt.org](https://llmstxt.org/)（Jeremy Howard / Answer.AI。2024-09-03 公開、**v2 は 2026-08-10 更新**）。 **spec が定めるのは `llms.txt` だけ**: …

How to install
mdr add shimo4228/claude-harness/llms-txt-writer@sha256:c9dcadb849ad2d18The line at the top of this page pins the label git:20261010.b5821aa, 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.
