What it does

X Growth Discover is an agent skill from Shudesu/x-harness-oss. X の海外バズ投稿(特に動画)を無料で発見し、翻訳+引用RT文面案つきでソース候補に登録する。トリガー: ネタ探し, ネタ発見, 海外バズ, discover, ソース収集, バズ収集

Its SKILL.md is about 330 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 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.

Example prompts

  • “/x-growth-discover”

Requirements

  • A credential in X_HARNESS_API_KEY
  • A credential in TWITTER_AUTH_TOKEN

Workflow steps

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

  1. 検索クエリを決める — ユーザーの発信ジャンルに合わせる。指定がなければ聞く。例
  2. scrape_search で発見 — type: "videos"(動画優先)または "top"、lang: "en"、minLikes: 1000 以上を目安。
  3. 候補を絞る — いいね数・views・自分のジャンルとの一致で上位を選ぶ。すでに登録済みか list_growth_sources で確認し重複登録しない。
  4. scrape_post で全文+動画情報を取得 — 返却の embedUrl は動画引用投稿に使える(x-growth-video スキル参照)。
  5. 翻訳+文面案を作る — textJa(自然な日本語訳)、summaryJa(1〜2文要約)、suggestedQuoteText(引用RT文面案 150〜400字: フック1行→空行→内容の分解→ひとこと感想)。
  6. add_growth_source で登録 — sourceTweetId / author / textEn / textJa / summaryJa / suggestedQuoteText / videoUrl / views / likes / theme を渡す。
  7. 報告 — 登録した件数とダッシュボード(管理画面の Growth → 海外ネタタブ)でレビューできることを伝える。

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

    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 these keys or tokens, usually read from environment variables:

    • X_HARNESS_API_KEY
    • TWITTER_AUTH_TOKEN

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

Context cost

X Growth Discover loads about 325 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 93 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~325

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: ネタ発見(海外バズ → ソース候補)

X Harness MCP の無料 scrape ツールで海外のバズ投稿を発見し、ダッシュボードでレビューできる形で D1 に登録する。X API 読み取り課金ゼロ。

前提

  • X Harness MCP がセットアップ済み(X_HARNESS_API_URL / X_HARNESS_API_KEY)
  • twitter-cli + TWITTER_AUTH_TOKEN / TWITTER_CT0(収集専用サブアカウント推奨)

手順

  1. 検索クエリを決める — ユーザーの発信ジャンルに合わせる。指定がなければ聞く。例:
    • claude code / AI agent / openai (AI系)
    • 複数クエリを回すと発見率が上がる(3〜10個)
  2. scrape_search で発見 — type: "videos"(動画優先)または "top"、lang: "en"、minLikes: 1000 以上を目安。
    • 注意: from: 演算子は 0 件になる。特定ユーザーは scrape_user_posts を使う。
  3. 候補を絞る — いいね数・views・自分のジャンルとの一致で上位を選ぶ。すでに登録済みか list_growth_sources で確認し重複登録しない。
  4. scrape_post で全文+動画情報を取得 — 返却の embedUrl は動画引用投稿に使える(x-growth-video スキル参照)。
  5. 翻訳+文面案を作る — textJa(自然な日本語訳)、summaryJa(1〜2文要約)、suggestedQuoteText(引用RT文面案 150〜400字: フック1行→空行→内容の分解→ひとこと感想)。
  6. add_growth_source で登録 — sourceTweetId / author / textEn / textJa / summaryJa / suggestedQuoteText / videoUrl / views / likes / theme を渡す。
  7. 報告 — 登録した件数とダッシュボード(管理画面の Growth → 海外ネタタブ)でレビューできることを伝える。

品質基準

  • 訳は直訳でなく「日本の読者が読んで意味がわかる」自然さ
  • theme は後でピラー記事と紐付けるためのタグ(例: ai-tools, automation, marketing)を一貫して付ける
