Three samples from Anthropic: • Token Weather: a context window forecast above your prompt • Blast Radius: pauses rm -rf or a force push and shows what it would change • Replay Theater: /replay steps through last turn's edits, one diff at a time https://github.com/anthropics/claude-code-playground/tree/main/claude-code/mods
【公式】 Claude Code の開発チームが、本体を自分好みに改造できる mods を公開しました😳 文脈の残量を天気で出す、危ないコマンドを止める、そんな見本が3つ付いています。 https://x.com/ClaudeDevs/status/2105721434807083061/video/1 2.1.287 以降なら plugin として入れるだけです。 ・Token Weather：文脈の埋まり具合を天気で表示 ・Blast Radius：rm -rf や強制 push を実行前に止める ・Replay Theater：書き換えを差分1件ずつ見返す 承認ボタンをビクビク押している身なら、Blast Radius だけでも入れたい。 文脈が埋まってきたら、削る道具も持っておくと止まりません。 トークンを減らす OSS 50個を、この下の記事で並べています👇 オープンソースはこちら👇 https://github.com/anthropics/claude-code-playground
Replay Theater：直前の編集を順に振り返る /replayで編集を1件ずつたどれます。 例えば複数ファイルのリファクタリング後に、「何をどう直したのか」を把握出来ます。 https://github.com/anthropics/claude-code-playground/blob/main/claude-code/mods/replay-theater/README.md
Blast Radius：削除・Git操作の影響を先に見る rmやgit reset --hardなどをいったん止め、影響するファイルやコミットを表示します。例えば「不要ファイルを整理して」と頼んだ際、消す対象を見てから実行・中止を選べます。 https://github.com/anthropics/claude-code-playground/blob/main/claude-code/mods/blast-radius/README.md
