npx claudepluginhub arkatom/claude-plugins --plugin session-hooks異系統 LLM (Codex Devil 並列、Codex 不可時は Claude Devil fallback) でタスクをレビューする 2 層 orchestrator + 任意の Skill に Devil 観点を動的策定して scaffold するメタスキルの 2 つを同梱。Claude 単独の自信過剰バイアスを抑え、観点の盲点を別系統で拾う。
Claude Code cost-saver trio (cost-monitor / skill-analyzer / cost-optimizer) + genshijin + core-instructions の統合 orchestrator plugin。SessionStart hook で軽量診断 + reminder、`/cost-saver-orchestrator:cost-saver` skill で詳細診断 + 4 段階強制力 (案内 / CLAUDE.md @import / settings.json 書換 / 全実装) を AskUserQuestion で対話的に選ばせて適用。書換系は 4 段防御 (dry-run → backup → atomic mktemp+mv → auto-restore)。利用者を「cost-saver 何ができるか不明」状態から「設定完了 + 各 plugin 機能把握済」へ能動的に案内。
ffmpeg を使った動画・音声ファイル形式変換 skill。mov↔mp4 / mov↔webm / 音声抽出 / GIF 化を preset 化済。Mac/Windows/Linux クロスプラットフォーム対応、ffmpeg 未インストール環境では OS 別 install 手順を提示。
