Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

marketing-release-handoff scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.

marketing-release-handoff

KIOKU の release 直後に PM session (本 skill 起動者) がマーケ部に投げる引き継ぎ資料 を構造化して生成する skill。バグ fix や内部改善は除外し、user が touch できる価値 + 訴求角度 + 記事ネタ のみに絞った markdown を tools/claude-brain/marketing/handoff/ に保存する。

いつ使うか

  • KIOKU の release (v0.X.Y tag) を publish した直後
  • マーケ部に「何が出たか / 何を訴求できるか」を PM side から説明したい時
  • 記事ネタ候補 (dev.to / Qiita / Zenn) を構造化して引き渡したい時

使わない場面:

  • Patch release (v0.X.Y hotfix) で user-facing な変化が無い時 → 手動で省略判断
  • マーケ担当が自力で Changelog 解読する運用に戻したい時 → 本 skill は PM→マーケ の橋渡し用

前提

  • release 作業 (tag + .mcpb + GitHub Release + README Changelog 10 言語) が既に完了していること
  • tools/claude-brain/app/README.md の Changelog に 対象 version の entry が存在すること
  • 参照正典: tools/claude-brain/marketing/handoff/kioku-marketing-handover.md (マーケ運用鉄則)、.claude/rules/marketing.md (マーケ関連 file 配置ルール)

起動

/marketing-release-handoff v0.7.0

引数省略時 (/marketing-release-handoff) は kioku 最新 tag を gh api repos/megaphone-tokyo/kioku/tags で自動検出。

実行手順 (skill 本体の処理)

Step 1: Release info 収集

  1. VERSION を確定: slash command 引数 (例: /marketing-release-handoff v0.7.0 の v0.7.0) が与えられていればそれを使う。省略時は latest tag を Bash で取得:

    gh api 'repos/megaphone-tokyo/kioku/tags?per_page=1' --jq '.[0].name'

    ※ この snippet 内の $1 / ${1:-...} を slash command 引数と混同しないこと。skill は引数を prompt 文脈で受け取り、shell 位置引数は空。<VERSION> は以降 v0.7.0 等の確定値に置換して使う。

  2. tag 情報と published 日を取得:

    gh release view "<VERSION>" --repo megaphone-tokyo/kioku --json tagName,publishedAt,assets

  3. handoff filename の日付 + NN 連番を決定: publishedAt を YYMMDD 形式に変換 (例: 2026-04-24 → 260424)、NN は既存 handoff の同日件数 +1 を ls tools/claude-brain/marketing/handoff/ | grep "^<YYMMDD>" で数えて決定 (該当無しなら 01)。

Step 2: Changelog 該当 entry 抽出 (LEARN#10 準拠)

  1. 必ず 以下 grep で heading 実在を verify (LEARN#10 精読必須):

    grep -n "^### .*— <VERSION>:" tools/claude-brain/app/README.md

    hit 無し → 即 abort。推測ベースで handoff 本文を書かず、user に以下を報告:

    Changelog entry 未作成の可能性。release cascade (parent PR → sync-to-app → kioku README PR → kioku main merge → post-release-sync) が完了していない疑い。LEARN#11 の 4 step を確認してください。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
