What it does

X Growth Video is an agent skill from Shudesu/x-harness-oss. 海外の動画バズを発見し、/video/1 URL で元動画を自分のツイート内に展開する動画引用投稿を生成・予約する。承認モード(デフォルト)とフルオートモード(--auto)。トリガー: 動画投稿, 動画ネタ, 動画引用, video, バズ動画

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation. It works with X (Twitter), Model Context Protocol and Cloudflare Workers. 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.

When your agent uses it

  • Productivity & Automation work in your project

Example prompts

  • “/x-growth-video”

Requirements

  • A credential in TWITTER_AUTH_TOKEN

Workflow steps

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

  1. 発見 — scrape_search を type: "videos", lang: "en", minLikes: 1000〜5000 で実行。ユーザーのジャンルに合うクエリを 3〜10 個回す。list_growth_sources で登録済みのものは除外。
  2. 動画情報取得 — 候補ごとに scrape_post で全文と embedUrl を取得。embedUrl が null(動画なし)の候補は捨てる。
  3. 口調学習 — scrape_user_posts でユーザー自身の直近投稿を取得し、文体を合わせる(初回のみでよい。学習結果を会話内で再利用してよい)。
  4. 文面生成 — 各候補につき 150〜400 字
  5. ピラー紐付け(任意) — ユーザーがピラー投稿(自分の代表記事ポスト)を設定している場合、テーマが一致すれば quoteTweetId にピラー投稿 ID を指定(引用RT×動画のダブル構造)。
  6. 予約
  7. 報告 — 作成本数・予約時刻・(承認モードなら)ダッシュボードでの承認が必要なことを伝える。

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

    Shell commands in SKILL.md call:

    • claude
    • codex

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • x.com

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • TWITTER_AUTH_TOKEN

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

Context cost

X Growth Video loads about 486 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 127 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~486

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: 動画引用投稿

動画は現在の X で最もインプレッションが出るフォーマット。このスキルは海外の動画バズを発見し、https://x.com/<author>/status/<id>/video/1 形式の URL を本文に貼ることで元動画を自分のツイート内に展開する投稿を作る(再アップなし・元投稿へのクレジット付き)。

モード

  • 承認モード(デフォルト): ドラフトを add_growth_draft で承認キューへ → ダッシュボードで ok/編集 → 予約
  • フルオートモード(--auto と明示された場合のみ): schedule_post で直接予約する。1回の実行で最大 3 本まで。

前提

  • X Harness MCP セットアップ済み + twitter-cli(TWITTER_AUTH_TOKEN / TWITTER_CT0、サブアカウント推奨)
  • コスト注意: 投稿(write)は X API 課金。URL 入りポストは $0.20/件(2026-07 時点)

手順

  1. 発見 — scrape_search を type: "videos", lang: "en", minLikes: 1000〜5000 で実行。ユーザーのジャンルに合うクエリを 3〜10 個回す。list_growth_sources で登録済みのものは除外。
  2. 動画情報取得 — 候補ごとに scrape_post で全文と embedUrl を取得。embedUrl が null(動画なし)の候補は捨てる。
  3. 口調学習 — scrape_user_posts でユーザー自身の直近投稿を取得し、文体を合わせる(初回のみでよい。学習結果を会話内で再利用してよい)。
  4. 文面生成 — 各候補につき 150〜400 字:
    • 1 行目: 価値が一目でわかる強フック(無料/公式/具体的数字が強い)
    • 空行 → 内容の分解(「内容はこんな感じ:」+ 箇条書き 3〜5 点)
    • ひとこと感想 or 読者への問いかけ
    • 末尾: via @<author> + embedUrl(この URL が動画として展開される)
    • 本文にそれ以外のリンクは入れない(リーチが下がる)
  5. ピラー紐付け(任意) — ユーザーがピラー投稿(自分の代表記事ポスト)を設定している場合、テーマが一致すれば quoteTweetId にピラー投稿 ID を指定(引用RT×動画のダブル構造)。
  6. 予約:
    • 承認モード: add_growth_draft(type: "video", scheduledAt は YYYY-MM-DDTHH:MM:SS+09:00 形式必須)
    • フルオート: schedule_post で同形式の scheduledAt。投稿時刻は 7:00〜22:00 (JST) に分散させる
  7. 報告 — 作成本数・予約時刻・(承認モードなら)ダッシュボードでの承認が必要なことを伝える。

定期実行(cron)

ユーザーが毎日自動で回したい場合の設定例を案内する:

bash
# Claude Code
30 5 * * * cd /path/to/project && claude -p "/x-growth-video --auto" --dangerously-skip-permissions

# Codex CLI
30 5 * * * cd /path/to/project && codex exec "x-growth-video スキルを --auto で実行"

品質・安全基準

  • 元投稿者のクレジット(via @author)必須
  • 同じ投稿者ばかり連続で使わない(1日の中で分散)
  • 政治・センシティブ・真偽不明の動画は選ばない
  • フルオートでも 1 実行 3 本まで(スパム判定回避)
