Summary

Expand the existing Traditional Chinese language option from the mode-selection screen to the rest of CatDesk's TUI.

The existing UiLanguage preference is reused, so this does not add a second localization system or change the configuration format.

Why

Traditional Chinese was previously selectable and persisted in ~/.catdesk/config.toml, but most of the runtime TUI still remained in English.

This made the language option feel incomplete once the user left the initial mode-selection screen.

This PR makes the existing language setting apply throughout the main CatDesk interface.

What changed

Traditional Chinese localization now covers:

  • main dashboard status labels and runtime states
  • session and all-time usage labels
  • connection flow labels and request counters
  • keys and log panel titles
  • Settings
  • tool-mode and widget-detail descriptions
  • browser selection
  • ngrok authtoken setup
  • ngrok static-domain setup
  • connector refresh instructions
  • MCP bootstrap progress
  • common copy / reveal / export toasts
  • common runtime log messages shown in the TUI

The main dashboard now displays labels such as 狀態, 模式, 工具模式, 伺服器, 工作區, 本機瀏覽器, 遠端除錯支援, 按鍵, and 紀錄 when Traditional Chinese is selected.

Log behavior

Runtime log messages are localized only for display in the Traditional Chinese TUI.

The underlying log entries and exported logs remain in English so that debugging, searching error messages, and reporting issues are not affected by localization.

Compatibility

English remains the default language.

The existing ui_language setting and persistence behavior are unchanged.

No MCP protocol, connector schema, or configuration-format changes are introduced.

Documentation

Updated both:

  • README.md
  • README.zh-TW.md

The documentation now clarifies that the language selection applies across the main TUI rather than only the mode-selection screen.

Validation

Traditional Chinese UI tests
Main dashboard localization test
Connector refresh localization test
Bootstrap localization test
cargo build --release
git diff --check

Full cargo test --release result:

  • 217 tests
  • 211 passed
  • 6 failed

The six failures are the existing macOS change_tracking absolute-path tests and are unrelated to this change.

Summary by CodeRabbit

  • New Features

    • Added Traditional Chinese localization across the dashboard, settings, browser selection, ngrok setup, connection guidance, notifications, and runtime messages.
    • Mode, tool, and theme labels and descriptions now display in the selected language.
    • Traditional Chinese rendering is supported throughout common setup and status screens.
    • Added the create_handoff tool, bringing the available tool counts to 11 for multi-tool mode and 4 for read-only mode.
  • Documentation

    • Updated the English and Traditional Chinese quick-start guides, FAQs, usage guidance, localization coverage, and exported-log behavior.

2597-2597: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Measure toast width in terminal cells.

render_toast uses UTF-8 byte length for the Rect width, while ratatui renders Paragraph text in terminal cells. Traditional Chinese messages therefore create oversized rectangles, which can shift the toast left and clip its area. Add unicode-width as a direct dependency and use its cell-width calculation.

@Xeift 你會希望宣傳廣告嗎

這本來是偏向我個人用的工具,市面上也有很多成熟的同類型專案
當然有很多優秀的開發者貢獻非常不錯
不過我是覺得大家想用就用吧,佛系維護就好不用特別推

另外我認為這種 MCP connector 當 Codex 用的時代快結束了,年底前這專案可能就沒意義了
第一個是 Plus Thinking 被從 102 分鐘砍到剩 25,再來是 Astra 在網頁版是直接用 Pro 推出
前陣子我的想法是 OAI 會全域縮減 Chat 模式的額度,但現在我認為未來 Chat 和 Work 會合併,然後共用一套額度
畢竟因為 Astra,連 Pro 20x 訂閱都跟著停,顯然他們算力不夠用要節流了
