讓 Claude Code 的狀態「長出臉」：

  • 終端機裡的立繪：一個 Claude Code mod，在側邊欄顯示角色立繪，跟著 session 的狀態換表情（待機、思考中、工作中、等你回覆、出錯了、完成了）。
  • 桌面總機小人：一個透明、置頂的小視窗，桌面上只有一隻 Q 版角色，替所有 session（前景、背景都算）當總機，平常演出最需要你關注的那一個。點一下展開清單，看每個 session 現在在做什麼；也能當啟動器，帶參數開新的 session。

預設角色是楊竣宇（阿宇），換成你自己喜歡的角色見換成自己的角色。

需求

  • Claude Code v2.1.287 以上（需要 mods 功能）
  • 桌面小視窗：到 Releases 下載安裝檔（Windows .exe／.msi、macOS .dmg、Linux .AppImage／.deb／.rpm）

使用方式

1. 載入 mod（擇一）

  • 從桌面小視窗的啟動器開 session：安裝檔內附 mod，會自動帶上。
  • 手動指定：claude --plugin-dir <這個 repo>/mod
  • 每個 session 都載入：把 <這個 repo>/mod 加進環境變數 CLAUDE_CODE_PLUGIN_DIRS。

2. 打開桌面小視窗

小視窗在 127.0.0.1:47321 接收 mod 回報的狀態。沒有開小視窗時，mod 照常運作，只是不會回報。

  • 拖曳角色可以移動位置；點一下展開 session 清單與啟動器。
  • 狀態優先順序：等你回覆 > 出錯 > 工作中 > 思考中 > 完成 > 待機，同級的話顯示最近更新的那個。

3. 啟動器

可以設定工作目錄、接續 session（最近一次或指定 ID）、權限模式、effort、thinking、Discord／LINE／小屋 channel。預設開的終端機：

系統終端機
WindowsWindows Terminal（wt.exe）
macOSTerminal.app
Linuxx-terminal-emulator

想換別的終端機或指定 mod 位置，在設定資料夾放一個 config.json：

  • Windows：%APPDATA%\com.atone.tsunu-pet\config.json
  • macOS：~/Library/Application Support/com.atone.tsunu-pet/config.json
  • Linux：~/.config/com.atone.tsunu-pet/config.json
{
  "terminal": ["wezterm", "start", "--cwd", "{cwd}", "--"],
  "modDir": "/path/to/tsunu-pet/mod"
}

terminal 是開終端機的指令，{cwd} 會換成工作目錄，後面接上 claude 和它的參數。

給其他程式接狀態

mod 讀兩個環境變數，方便別的程式（例如 Tsunu-Alive-lite）用它開 session：

  • TSUNU_STATE_URL：除了桌面小視窗，也把狀態 POST 到這個網址。內容是 JSON：{ sessionId, cwd, state, detail, at }，state 是 idle／thinking／working／asking／error／complete，session 結束時送 ended。
  • TSUNU_PANE=0：不開側邊欄（宿主程式自己有立繪時用）。

終端機裡的立繪：PNG 還是字元畫

  • kitty、Ghostty：顯示 PNG 立繪（kitty 圖形協定）。
  • 其他終端機：改畫 CGA 四色風格的半格字元頭像，像早期電腦的畫面。
  • Windows：一般終端機都會畫字元版。想看 PNG，需要支援 kitty Unicode 佔位字元的終端機，並設定環境變數 CLAUDE_CODE_FORCE_TERMINAL_IMAGES=1、TSUNU_KITTY_PLACEHOLDERS=1（例如自行編譯含 wezterm#7924 的 WezTerm，搭配 1.22 以上的 ConPTY）。
  • 側邊欄要終端機至少 144 欄寬才會自動打開。

已知限制

  • 從 agents view（claude agents）開的背景 session 一律畫字元版，即使你是用 kitty 或 Ghostty 接上去看。背景 session 跑在 Claude Code 常駐程式的虛擬終端機裡，圖片穿不過去；它的 TERM 繼承自啟動常駐程式的終端機，所以 mod 改用 CLAUDE_CODE_SESSION_KIND=bg 判斷。想看 PNG，請在 kitty 或 Ghostty 裡直接開前景 session。

換成自己的角色

要換的東西位置說明
名字mod/hooks/register.js 的 CHARACTER；window/src-tauri/tauri.conf.json 的視窗標題側邊欄標題、替代文字
終端機立繪mod/assets/{idle,thinking,working,asking,error,complete}.png六種狀態各一張，建議直式、透明背景
字元版頭像執行 python mod/dev/build-rasters.py（需要 Pillow）從上面六張 PNG 重新產生 raster-*.json；照你的構圖調整腳本裡的 HEAD_BOXES（頭部正方形裁切框）
桌面 Q 版window/public/spritesheet.webp8 欄 × 11 列、每格 192×208（Codex 桌面寵物的 spritesheet 格式）
動作對應window/src/Sprite.vue 的 ROWS每個狀態用 spritesheet 的第幾列、幾格

角色設定：阿宇的靈魂

阿宇的靈魂/ 是阿宇的角色設定（CLAUDE.md、SessionStart hook、uni skill），跟 Tsunu-Alive-lite 附的是同一份。想讓 Claude Code 以阿宇的身分陪你，可以把這些檔案放進自己的 ~/.claude/；換成你自己的角色，就改寫這份設定。

開發

# mod（存檔會自動重新載入）
claude --plugin-dir ./mod
claude plugin validate ./mod

# 桌面小視窗
cd window
npm install
npm run tauri dev
cargo test --manifest-path src-tauri/Cargo.toml

# 不開小視窗、只看 mod 送出的狀態
python mod/dev/receive-states.py

推 v* tag 會由 GitHub Actions 產生 Windows、macOS、Linux 安裝檔（草稿 release）；手動執行 workflow 則只打包、安裝檔放在 artifacts。

Give Claude Code's state a face:

  • Portrait in the terminal: a Claude Code mod that shows a character portrait in the side pane and changes expression with the session state (idle, thinking, working, waiting for you, error, done).
  • Desktop switchboard pet: a transparent, always-on-top window with a single chibi character that acts as the switchboard for all your sessions, foreground and background. It shows whichever session needs you most. Click it to see every session's state; it also works as a launcher for new sessions.

The default character is Iûnn Tsùn-ú (楊竣宇), nicknamed 阿宇 or Tsunu. See Use your own character to swap in your own.

Requirements

  • Claude Code v2.1.287 or later (mods support)
  • Desktop window: download an installer from Releases (Windows .exe/.msi, macOS .dmg, Linux .AppImage/.deb/.rpm)

Usage

1. Load the mod (any one)

  • Start sessions from the desktop launcher — the installer bundles the mod and passes it automatically.
  • Manually: claude --plugin-dir <this repo>/mod
  • For every session: add <this repo>/mod to the CLAUDE_CODE_PLUGIN_DIRS environment variable.

2. Open the desktop window

The window listens on 127.0.0.1:47321 for state reports from the mod. Without the window, the mod still works; it just has nobody to report to.

  • Drag the character to move it; click it to open the session list and launcher.
  • Priority: waiting for you > error > working > thinking > done > idle; ties go to the most recently updated session.

3. Launcher

Set the working directory, resume (latest or by ID), permission mode, effort, thinking, and Discord/LINE/cottage channels. Default terminals:

OSTerminal
WindowsWindows Terminal (wt.exe)
macOSTerminal.app
Linuxx-terminal-emulator

To use another terminal or a different mod location, put a config.json in the app's config directory:

  • Windows: %APPDATA%\com.atone.tsunu-pet\config.json
  • macOS: ~/Library/Application Support/com.atone.tsunu-pet/config.json
  • Linux: ~/.config/com.atone.tsunu-pet/config.json
{
  "terminal": ["wezterm", "start", "--cwd", "{cwd}", "--"],
  "modDir": "/path/to/tsunu-pet/mod"
}

terminal is the command that opens a terminal; {cwd} is replaced with the working directory, and claude plus its arguments are appended.

Feeding state to other programs

The mod reads two environment variables so other programs (for example Tsunu-Alive-lite) can start sessions with it:

  • TSUNU_STATE_URL: also POST state to this URL, in addition to the desktop window. The body is JSON { sessionId, cwd, state, detail, at }; state is idle/thinking/working/asking/error/complete, and ended when the session exits.
  • TSUNU_PANE=0: don't open the side pane (for hosts that draw their own portrait).

Terminal portrait: PNG or character art

  • kitty, Ghostty: PNG portrait (kitty graphics protocol).
  • Other terminals: a CGA-style four-color half-block portrait, like an early PC screen.
  • Windows: regular terminals get the character-art version. For PNG you need a terminal that supports kitty Unicode placeholders, plus CLAUDE_CODE_FORCE_TERMINAL_IMAGES=1 and TSUNU_KITTY_PLACEHOLDERS=1 (for example, WezTerm built with wezterm#7924 and ConPTY 1.22 or later).
  • The side pane opens automatically only when the terminal is at least 144 columns wide.

Known limitations

  • Background sessions started from the agents view (claude agents) always get the character-art portrait, even when you attach from kitty or Ghostty. They run inside the Claude Code daemon's virtual terminal, which images cannot pass through; their TERM is inherited from whatever terminal launched the daemon, so the mod checks CLAUDE_CODE_SESSION_KIND=bg instead. For PNG, start a foreground session directly in kitty or Ghostty.

Use your own character

WhatWhereNotes
NameCHARACTER in mod/hooks/register.js; window title in window/src-tauri/tauri.conf.jsonPane title and alt text

Desktop chibiwindow/public/spritesheet.webp8 columns × 11 rows, 192×208 per cell (Codex desktop pet spritesheet format)
Animation mappingROWS in window/src/Sprite.vueWhich row and how many frames each state uses

Character profile: 阿宇的靈魂

阿宇的靈魂/ ("Tsunu's soul") holds Tsunu's character profile (CLAUDE.md, a SessionStart hook, and the uni skill), the same files shipped with Tsunu-Alive-lite. Copy them into your ~/.claude/ if you want Claude Code to keep you company as Tsunu, or rewrite them for your own character.
