關於這個 mod

🎃 Claude Code 的萬聖節

Claude Code 終端機的萬聖節主題。

提示列周圍的鬧鬼邊框。 蝙蝠、葉子和月亮停在提示列上方的紫羅蘭色邊緣。下方是一條苔蘚藤蔓，南瓜燈在上面隨機成簇生長，把閃爍的光映到藤蔓上。幽靈偶爾沿著頂端飄過，拖著一縷靈質。每個工作階段都有自己的隨機版面。
飛過對話區的蝙蝠。 一小群蝙蝠會完整飛過聊天內容：從一側飛入、從另一側飛出，沿著平緩弧線上升或下降，有些慢慢巡航，有些快速掠過。
詭異文字。 轉圈行會顯示 Brewing…、Summoning… 或 Stirring the cauldron… 等文字，完成的回合會顯示 Haunted for 12s。
敢用的話，還有詭異音效。 每次按鍵都會發出蝙蝠般的吱聲，偶爾還會像閃電一樣劈啪作響。按 Enter 送出回答時，會播放反派的 mwah-ha-ha、女巫的尖笑、惡魔的笑聲、哀號幽靈、管風琴或雷鳴聲。每種 Enter 音效都會先播放一次才開始重複，而且同一種不會連續播放兩次。開啟前音效都是關閉的。

安裝

在 Claude Code 中：

/plugin marketplace add phuclh/claude-halloween
/plugin install halloween@phuclh-plugins

或從 shell 執行：

claude plugin marketplace add phuclh/claude-halloween
claude plugin install halloween@phuclh-plugins

接著啟動新的工作階段。

使用

/halloween 可切換主題。你的選擇會在不同工作階段之間保留。
/halloween sounds 可切換音效，設定也會被記住。音效只在 macOS 播放：Claude Code 會用 afplay 播放，Linux 或 Windows 不會播放任何聲音。
如果 90 秒內沒有輸入，也沒有 Claude 的工作，動畫會暫停並停止使用 CPU。你開始輸入或 Claude 開始工作後，它會立即恢復。

需求

全螢幕模式用於顯示邊框和蝙蝠：在 ~/.claude/settings.json 設定 "tui": "fullscreen"，或使用 /tui 切換。在其他畫面中，你會看到詭異文字和提示列上的小花環。
較新的 Claude Code。 主題使用 Claude Code 的 early-access function-hook API，這個 API 可能在版本之間變動。以 Claude Code 2.1.287 建置並測試。

效能

動畫執行時，主題每秒重繪畫面 8 次，在 110×40 的終端機上約使用一個 CPU 核心的 8–11%。暫停後不會耗用資源。

開啟音效時，每次按鍵都會啟動一個短暫的 afplay，間隔最多每 70 ms 一次。每次按鍵約增加 0.02 s 的 CPU 使用量，而且只在輸入時發生。

開發

claude --plugin-dir ./plugins/halloween       # 從此資料夾執行
claude plugin validate ./plugins/halloween    # 檢查 manifest 和 hooks
claude plugin test ./plugins/halloween        # 執行測試

上面的示範由外掛自己的邊框和飛行程式碼繪製。修改後要再次產生它：

npx -p typescript tsc -p scripts
node .demo-build/scripts/render-demo.js > assets/demo.svg

音效由 scripts/render-sounds.ts 使用振盪器、雜訊和濾波器合成；笑聲來自小型共振峰合成器。沒有錄音或取樣。要重新產生到 plugins/halloween/sounds/：

npx -p typescript tsc -p scripts
node .demo-build/scripts/render-sounds.js

安裝

請先查看作者 README，確認 marketplace 與外掛名稱；指令可能隨儲存庫結構而變動。

claude plugin marketplace add phuclh/claude-halloween
claude plugin install halloween

原文 / README

🎃 Halloween for Claude Code

A Halloween theme for the Claude Code terminal.

A haunted frame around the prompt. Bats, leaves and a moon perch on a violet edge above the prompt. Below it runs a moss vine where jack-o'-lanterns grow in random clumps and flicker their glow onto the vine. A ghost drifts along the top every so often, trailing ectoplasm. Every session gets its own random layout.
Bats across the conversation. A small flock flies whole journeys over your chat: in from one side and out the other, rising or falling along a gentle arc, some cruising and some darting.
Spooky words. The spinner says things like Brewing…, Summoning… or Stirring the cauldron…, and finished turns read Haunted for 12s.
Spooky sounds, if you dare. Each keystroke squeaks like a bat or, now and then, cracks like lightning. Enter answers with a villain's mwah-ha-ha, a witch's cackle, a demon's laugh, a wailing ghost, a pipe organ or a thunderclap. Every Enter sound plays once before any repeats, and the same one never plays twice in a row. Sounds are off until you turn them on.

Install

In Claude Code:

/plugin marketplace add phuclh/claude-halloween
/plugin install halloween@phuclh-plugins

Or from a shell:

claude plugin marketplace add phuclh/claude-halloween
claude plugin install halloween@phuclh-plugins

Then start a new session.

Use

/halloween turns the theme off and on. Your choice is remembered across sessions.
/halloween sounds turns the sounds on and off, and is remembered too. Sounds play on macOS only: Claude Code plays them with afplay, and plays nothing on Linux or Windows.
After 90 seconds with no typing and no work from Claude, the animation pauses and stops using CPU. It wakes as soon as you type or Claude starts working.

Requirements

Fullscreen mode for the frame and the bats: set "tui": "fullscreen" in ~/.claude/settings.json, or switch with /tui. On other screens you get the spooky words and a small garland on the hint line.
A recent Claude Code. The theme uses Claude Code's early-access function-hook API, which may change between releases. Built and tested on Claude Code 2.1.287.

Performance

While animating, the theme redraws the screen 8 times a second, which costs about 8–11% of one CPU core on a 110×40 terminal. Once paused, it costs nothing.

With sounds on, each keystroke starts a short afplay, at most one every 70 ms. That adds about 0.02 s of CPU per keystroke, and only while you type.

Develop

claude --plugin-dir ./plugins/halloween       # run it from this folder
claude plugin validate ./plugins/halloween    # check the manifest and hooks
claude plugin test ./plugins/halloween        # run the tests

The demo above is drawn by the plugin's own frame and flight code. To render it again after a change:

npx -p typescript tsc -p scripts
node .demo-build/scripts/render-demo.js > assets/demo.svg

The sounds are synthesized from oscillators, noise and filters by scripts/render-sounds.ts; the laughs come from a small formant synthesizer. Nothing is recorded or sampled. To render them again into plugins/halloween/sounds/:

npx -p typescript tsc -p scripts
node .demo-build/scripts/render-sounds.js
