What it does

X Growth Article is an agent skill from Shudesu/x-harness-oss. 収集済みソース候補から X の長文記事(4,000〜7,000字)を自分の口調で生成し、下書き保存する。トリガー: 記事生成, 記事を書く, 長文記事, ピラー記事, article

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Model Context Protocol, Cloudflare Workers and X (Twitter). The repository describes itself as: X Harness — self-hosted X (Twitter) scheduling, DM and analytics on Cloudflare Workers, with MCP and TypeScript SDK. By Shudesu (野田修一). The licence is MIT.

  • “/x-growth-article”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. ネタ選定 — list_growth_sources(status: new)から、テーマの近い 1〜5 件を選ぶ。ユーザーが指定していればそれを使う。
  2. 口調学習(必須) — scrape_user_posts でユーザー自身の直近投稿 30〜50 件を取得し、文体の特徴(一人称、語尾、絵文字の使い方、改行リズム、よく使う言い回し)を 5 項目程度に言語化してから書く。これを飛ばすと AI 臭い記事になる。
  3. 構成を作る — 目安: タイトル(数字か具体的ベネフィット入り)+ セクション 6〜10 本 + まとめ。読者は「この分野を知らない日本人」を想定し、海外の権威名・専門用語は一言説明を添える。
  4. 本文を書く — 4,000〜7,000 字。各セクションは「主張 → 具体例(ソースの内容)→ 読者が今日できること」の順。ソース元は本文中でクレジットする(@author)。
  5. 画像(任意) — 画像生成ツールが使える環境(codex の $imagegen 等)ならヘッダー画像を作り、Worker の /api/growth/articles/image にアップロードして imageUrl に設定。本文中の画像は、bodyMd に段落として単独で…
  6. save_growth_article で下書き保存 — xAccountId / title / bodyMd / theme / sourceTweetIds を渡す。
  7. 報告 — ダッシュボード(Growth → 記事タブ)でレビューし、公開する場合は create_article → publish_article(X Premium)を使うことを伝える。このスキル内で publish まで進めない。 なお X 側のレート制限は draft…

What it can do on your machine

Read from SKILL.md and the folder at commit 1c903a3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

X Growth Article loads about 377 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 107 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~377

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

X Growth: 長文記事生成

ソース候補(海外ネタ)をもとに、X の Articles 機能向け長文記事を生成して下書き保存する。自動公開はしない — ダッシュボードでレビュー後、ユーザーが公開を決める。

前提

  • X Harness MCP セットアップ済み
  • 公開には X Premium が必要(2026年1月に Premium+ 限定から全 Premium プランへ開放。下書き保存だけなら不要)

手順

  1. ネタ選定 — list_growth_sources(status: new)から、テーマの近い 1〜5 件を選ぶ。ユーザーが指定していればそれを使う。
  2. 口調学習(必須) — scrape_user_posts でユーザー自身の直近投稿 30〜50 件を取得し、文体の特徴(一人称、語尾、絵文字の使い方、改行リズム、よく使う言い回し)を 5 項目程度に言語化してから書く。これを飛ばすと AI 臭い記事になる。
  3. 構成を作る — 目安: タイトル(数字か具体的ベネフィット入り)+ セクション 6〜10 本 + まとめ。読者は「この分野を知らない日本人」を想定し、海外の権威名・専門用語は一言説明を添える。
  4. 本文を書く — 4,000〜7,000 字。各セクションは「主張 → 具体例(ソースの内容)→ 読者が今日できること」の順。ソース元は本文中でクレジットする(@author)。
  5. 画像(任意) — 画像生成ツールが使える環境(codex の $imagegen 等)ならヘッダー画像を作り、Worker の /api/growth/articles/image にアップロードして imageUrl に設定。本文中の画像は、bodyMd に段落として単独で ![キャプション](https://...) を書いておけば、公開時の create_article が自動で fetch → X にアップロード → インライン画像にする(URL は https 必須・到達可能であること)。なければ画像なしで保存してよい。
  6. save_growth_article で下書き保存 — xAccountId / title / bodyMd / theme / sourceTweetIds を渡す。
  7. 報告 — ダッシュボード(Growth → 記事タブ)でレビューし、公開する場合は create_article → publish_article(X Premium)を使うことを伝える。このスキル内で publish まで進めない。 なお X 側のレート制限は draft 作成 10件/24h(バリデーションエラーでも消費)・publish 5件/24h(詳細は docs/manual/07-articles-api.md)。

品質基準

  • 「読んだ人が今日 1 つ行動できる」記事になっているか
  • 翻訳調・箇条書きの羅列・「いかがでしたか」系の締めは禁止
  • 数字・固有名詞はソース候補の実データを使う(捏造しない)
