mokkan
Cross-session reminders: /mokkan toggles a live pane with your TODOs, Reminders and Archived tabs, /mokkan <command> runs push, in, edit, ack, done and the rest at once, and the /mokkan:mokkan skill lets Claude do it for you.
何をするか
- 欄・トーストを描く
- classic.SessionStart・prompt.edit・session.start・ui.close ほか 1 個にフックする
- ターンをまたいで自分の状態を持つ
- プロセスを起こす
良いところ
- ネットワークに出ない
- TypeScript で書かれている
- デスクトップ専用の分岐がある
- エラーを扱う

// Each value below stands for one the mod works out at run time; put in your own.

コードが呼ぶもの

コードから読み取ったデザイン
読み取ったコミットのソースから描いたもので、動かした結果ではありません。一覧は 3 回描き、条件はデスクトップアプリで描く最初の分岐を取り、動かしたときにだけ決まる値は仮の例(点線の下線)にするか省きます。色と書体はこのサイトのものです。
コードから読めること
2026-10-06 に読んだコミット 2e6914fc76be のソースから。最初のまとまりが載せる条件で、残りは自分で判断するための材料です。後のコミットは、次に読むまで見ていません。
| 載せる条件: 確かめやすいコード | |
|---|---|
| 入口を読んだ | hooks/hooks.json が名指すモジュールをすべて読んだ。claude-plugin/hooks/pane.tsx |
| 解析できる | すべてのファイルが TypeScript か JavaScript として解析できる。1 ファイルを解析 |
| コードが Mod の中で完結 | import は Mod 自身のファイルかエンジンのモジュールだけ。パッケージも require もない。コードはすべて Mod の中 |
| 読める | 圧縮した行・eval・new Function・計算した道の import()・符号化した塊がない。圧縮・eval・符号化した塊なし |
| 呼び出しが見える | 通信とプログラム起動はその場で $.http.fetch・$.process.run と書き、他へ渡さない。外への呼び出しはすべてその場の $ で |
| 入れる前に自分で判断する材料 | |
| 描く場所 | コードから読んだ、描く先。ターミナル・デスクトップアプリ・両方・何も描かない(フックだけ: 見張りやプロンプトの書き換え)のどれか。出すだけで、外す理由にはしない。ターミナルとデスクトップアプリに同じように描く |
| 入れる手順 | リポジトリ自身の .claude-plugin/marketplace.json にこの Mod が載っていて、ページに書いた手順でそのマーケットプレイスから入れられるか。リポジトリの .claude-plugin/marketplace.json に載っており、そこから入れられる |
| Windows のプログラム | $.process で起動するプログラムが Windows にあるか(tail・date・open・osascript・/usr/… などは無い)。Windows にないプログラムを使わない |
| 通信 | fetch の送り先(https のホスト)がコードに書いてあるか。通信なし |
| プログラム | 起動するプログラムの名前がコードに書いてあり、シェル・インタプリタ・通信用の道具でないか。claude-plugin/hooks/pane.tsx:83 実行時に決まるプログラム; claude-plugin/hooks/pane.tsx:113 実行時に決まるプログラム |
| 読んで送る | ファイルや環境変数を読み、かつ通信するか。通信しない |
| ソースの鍵 | ソースに API キーや秘密鍵らしきものがあるか。ソースに鍵なし |
| ライセンス | オープンなライセンス(MIT・Apache-2.0・BSD・ISC・Unlicense・0BSD・CC0)で全文があれば、modscode にコードを載せる。違えばリンクだけ。MIT |
コードの文面を読んだだけで、安全の審査ではありません。動かしてはおらず、起動するプログラムの中で何が起きるかも見えません。入れる前の確認はあなたの役目です。 載せる条件
入れる
入れる前に、必ず自分で確かめてください。Mod はサンドボックスなしで、あなたの権限で動きます。modscode はこのコードの安全を保証しません。下のコードを読み(またはフォルダーで claude plugin validate .)、触るものを見て、読んだコミットを入れてください。
リポジトリがそのままマーケットプレイスです。このマーケットプレイスを足し(ターミナルでは次のコマンド、デスクトップアプリではプラグインの設定)、そこから Mod を入れます。
/plugin marketplace add vicmpen/mokkan/plugin install mokkan@mokkan入るのはマーケットプレイスの最新のコミットで、ここで読んだもの(2e6914fc76be)と違うことがあります。入れる前に見比べてください。
