+name: gopeed-file-category-icons
+description: Design or revise Gopeed file-classification icons as one cohesive SVG-to-Flutter icon font. Use for file types, generic and protocol-marked folders, unknown files, and extension-to-icon taxonomy; do not use for launcher, navigation, action, or status icons.
+---
+
+# Gopeed File Category Icons
+
+Maintain Gopeed's file-classification visual language and its deterministic SVG → TTF → Flutter `IconData` pipeline.
+
+The canonical editable materials live in `design/file-category-icons/`, outside the Flutter project. Read its `README.md` before changing any source. Do not add that directory to Flutter assets.
+
+## Classification grammar
+
+- A directory is always a folder outline. Add a classification or protocol mark only when one is known; otherwise leave the folder empty.
+- A non-directory is always a file outline plus its classification mark.
+- An unknown file is an empty file outline. Do not invent a generic interior mark.
+- Transfer state is separate from classification. Never replace a file glyph with paused, failed, completed, or downloading artwork.
+- Keep this skill scoped to file browsing, task assets, extension classification, and the font that renders those categories.
+
+## Workflow
+
+1. Read `design/file-category-icons/README.md`, then inspect its manifest, the classification mapping, real task-card size, and file-tree size. Read [references/style-guide.md](references/style-guide.md) for every visual revision.
+2. Preserve the shared file or folder shell. Redraw only the classification mark unless the task explicitly revises the complete system.
+3. Create 24×24 SVG sources containing only closed, filled `<path>` geometry. Convert strokes and lettering to paths; never leave `<text>`, live strokes, masks, clipping, filters, or external references.
+4. Keep every decorated mark inside the documented safe area. Reject any mark that touches or visually merges with the shell at 16 or 20 px.
+5. Preserve existing names and codepoints. Omit the codepoint only for a new category, then allocate it with the builder. Bump the font version for a visual revision.
+6. Rebuild the complete TTF and generated Dart class, then generate the multi-size contact sheet.
+7. Inspect 16, 20, 24, and 32 px in light and dark swatches. Check the actual Flutter task card and task-detail file tree when their sizes differ from the sheet.
+8. Run the relevant classification tests, `flutter analyze`, and `flutter test` after integration changes.
+
+## Tool setup
+
+The scripts require the pinned packages in `scripts/requirements.txt`. Keep the environment local and untracked:
+
+```bash
+python3 -m venv .agent/skills/gopeed-file-category-icons/.venv
+.agent/skills/gopeed-file-category-icons/.venv/bin/pip install -r .agent/skills/gopeed-file-category-icons/scripts/requirements.txt
+```
+
+Build and preview a manifest:
+
+```bash
+.agent/skills/gopeed-file-category-icons/.venv/bin/python .agent/skills/gopeed-file-category-icons/scripts/build_icon_font.py --manifest design/file-category-icons/manifest.json --allocate-codepoints
+.agent/skills/gopeed-file-category-icons/.venv/bin/python .agent/skills/gopeed-file-category-icons/scripts/preview_icon_font.py --manifest design/file-category-icons/manifest.json
+```
+
+Use [assets/manifest.example.json](assets/manifest.example.json) and [assets/folder-symbol-template.svg](assets/folder-symbol-template.svg) only as structural starting points.
+
+## Invariants
+
+- Existing codepoints are API: never renumber or reuse one unless the user explicitly approves a breaking migration.
+- `design/file-category-icons/` is the sole editable source of truth. Flutter keeps only the generated runtime TTF and Dart constants.
+- Never add the design-material directory to `pubspec.yaml`; it must remain outside the packaged Flutter asset graph.
+- The manifest is the source of truth. Do not hand-edit generated Dart constants or patch the binary font.
+- Keep icon names lowercase `snake_case`; the generator emits lowerCamelCase Dart fields.
+- File and folder shells in the same revision must share outline weight, baseline, fold/tab geometry, and optical scale.
+- Prefer a recognizable classification symbol over lettering. If lettering is necessary, convert it to geometry and prove it remains legible at 16 px; PDF-like multi-letter marks need deliberate spacing rather than scaling text into the available area.
+- New classification groups require both an extension/domain mapping and a glyph. Do not add a glyph that no classifier can reach.
+- Rebuild the complete font after every source change so all platforms consume the same binary.

+# Gopeed file-category icon style
+
+## Composition
+
+- Unknown file: empty file shell.
+- Known file: file shell plus one classification mark.
+- Generic folder: empty folder shell.
+- Known or protocol folder: folder shell plus one classification mark.
+- Status and actions never belong inside a classification glyph.
+
+## Geometry
+
+- Use a `0 0 24 24` viewBox and keep the optical drawing inside `2…22` on both axes.
+- Use the current shared shell as the source of truth. The established file shell spans roughly `x=3…21` with a 1.5-unit outline; do not silently introduce a heavier one-off border.
+- Keep decorated marks approximately inside `x=6.2…17.8` and `y=9.2…19`. Preserve at least 1.5 units of visible separation from the shell wherever its interior edge is closer.
+- Prefer radii around 1.5–2 units, consistent terminal shapes, and simple silhouettes. Avoid details or gaps below 1.25 units.
+- Center by optical mass rather than bounding-box arithmetic when the shape has a tab, arrow, or asymmetric label.
+- Use non-zero winding for counters and holes; reverse inner-contour direction where a cutout is required.
+
+## Classification marks
+
+- Use one dominant mark, not several miniature objects.
+- Prefer semantic geometry: play for video, note for audio, image silhouette for images, grid for spreadsheets, a zipper for archive/compressed files, and a cylinder for databases.
+- Avoid lettering when a semantic mark is clearer. When a conventional label such as PDF is retained, build each letter as filled geometry with at least 1.25-unit stems and explicit inter-letter gaps.
+- Keep an empty file truly empty. A question mark, star, or extension text changes its meaning.
+
+## Protocol-marked folders
+
+- Keep the folder silhouette recognizable before adding the protocol symbol.
+- Place a simple filled protocol symbol in the lower folder body with clear space from every edge.
+- Prefer semantic marks such as a magnet/swarm for BitTorrent or a donkey/server-network mark for ED2K. Do not default to acronym lettering.
+- Let the visible folder occupy about 80–85% of the 24-unit canvas. Avoid adding generator padding on top of the SVG optical margin; double padding makes Flutter icons look undersized.
+- Compare optical center and occupied area against Flutter's `folder_outlined` at the actual widget size, not only in an enlarged preview.
+
+## Consistency checks
+
+- Compare new icons beside at least one existing folder icon and one file-type icon.
+- Inspect the generated contact sheet at 16, 20, 24, and 32 px on light and dark swatches.
+- Reject icons that depend on color, contain live text/strokes, have inconsistent baseline/weight, drift off center, become ambiguous at 16 px, or leave less than the shared safe-area separation from the shell.
+- Compare decorated icons against both empty shells. Interior marks must not make the shell look heavier by merging into its border.
+
+## Flutter usage
+
+Register the generated TTF under `flutter.fonts` using the exact `fontFamily` from the manifest. Use the generated Dart constants rather than raw codepoints. Render icon-font glyphs with `Icon`; do not use `Text` because icon sizing and semantics should follow Flutter's icon pipeline.

 ## Translation
 
-The internationalization files of Gopeed are located in the `ui/flutter/assets/locales` directory.
+Flutter translations are ARB files in `ui/flutter/lib/l10n`. Use `app_en.arb` as the source template,
-You only need to add the corresponding language file in this directory.
+then edit or add `app_<locale>.arb` (for example, `app_de.arb` or `app_zh_TW.arb`). Every locale must
+contain the same message keys as the English template.
 
+Translate message values only, and do not rename variables inside braces such as `{count}` and `{name}`.
+Do not translate metadata keys prefixed with `@`. Submit only the ARB source files you changed; do not generate or commit
+`app_localizations*.dart`. The pull-request CI automatically validates the catalogs, generates the
+localization code, and checks its integration.
 
-Generate locales after you edit locales:
+The following examples show both the ARB definition and the text users see after the app supplies values.
 
+1. Insert a variable into a message
 
-```
+   ARB definition:
-get generate locales 
-```
 
-Please refer to `en_us.dart` for translation.
+   ```json
+   "welcomeUser": "Hola, {name}"
+   ```
+
+   Rendered result: when `name = Ana`, users see “Hola, Ana”. You may reorder the sentence, but keep `{name}`.
+
+2. Display different text for different quantities
+
+   ARB definition:
+
+   ```json
+   "fileCount": "{count, plural, =0{No hay archivos} =1{1 archivo} other{{count} archivos}}"
+   ```
+
+   Rendered results:
+
+   - `count = 0` → “No hay archivos”
+   - `count = 1` → “1 archivo”
+   - `count = 3` → “3 archivos”
+
+   `=0`, `=1`, and `other` mean zero, one, and every other quantity. Translate only the user-visible text
+   inside each branch.
+
+3. Display different text for different values
+
+   ARB definition:
+
+   ```json
+   "taskState": "{state, select, running{En curso} paused{En pausa} other{Desconocido}}"
+   ```
+
+   Rendered results:
+
+   - `state = running` → “En curso”
+   - `state = paused` → “En pausa”
+   - Any other value → “Desconocido”
+
+   `running`, `paused`, and `other` are values supplied by the app. Do not translate them; translate only
+   the display text inside the following braces.

+`app_localizations*.dart` は生成もコミットも不要です。PR の CI が全言語を検証し、国際化コードを生成して
+統合結果を確認します。
 
-ロケール編集後にロケールを生成:

+1. メッセージに変数を挿入する
 
-```
+   ARB 定義：
-get generate locales

-翻訳については `en_us.dart` を参照してください。
+   ```json

+   ARB 定義：
+
+   ```json
+   "fileCount": "{count, plural, =0{ファイルなし} =1{1 個のファイル} other{{count} 個のファイル}}"

+   - `count = 0` →「ファイルなし」
+   - `count = 1` →「1 個のファイル」
+   - `count = 3` →「3 個のファイル」
+
+   `=0`、`=1`、`other` はそれぞれ 0、1、その他の数量を表します。各分岐の中で画面に表示される文字だけを翻訳します。

+# Hướng dẫn đóng góp cho Gopeed
+
+Trước tiên, cảm ơn bạn đã quan tâm đến việc đóng góp cho Gopeed. Hướng dẫn này sẽ giúp bạn tham gia
+phát triển Gopeed một cách tốt hơn.
+
+## Mô tả nhánh
+
+Dự án này chỉ có một nhánh chính duy nhất, đó là nhánh `main`. Nếu bạn muốn tham gia vào
+phát triển Gopeed, hãy fork dự án này trước, sau đó phát triển trong dự án fork của bạn. Sau khi
+hoàn thành phát triển, gửi một PR đến dự án này và merge vào nhánh `main`.
+
+## Phát triển cục bộ
+
+Đề nghị phát triển và gỡ lỗi thông qua web. Đầu tiên, khởi động dịch vụ backend bằng cách chạy
+lệnh `go run cmd/api/main.go` trong dòng lệnh, cổng mặc định của dịch vụ là `9999`, sau đó
+khởi động dự án flutter frontend trong chế độ `debug` để chạy.
+
+## Dịch thuật
+
+Các bản dịch Flutter là tệp ARB trong `ui/flutter/lib/l10n`. Hãy dùng `app_en.arb` làm mẫu nguồn,
+sau đó sửa hoặc thêm `app_<locale>.arb` (ví dụ `app_de.arb` hoặc `app_zh_TW.arb`). Mỗi ngôn ngữ phải
+có cùng các khóa thông điệp như mẫu tiếng Anh.
+
+Chỉ dịch giá trị thông điệp; không đổi tên biến trong dấu ngoặc nhọn như `{count}` và `{name}`. Không dịch khóa
+siêu dữ liệu bắt đầu bằng `@`. Chỉ commit các tệp nguồn ARB đã thay đổi; không cần tạo hoặc commit
+`app_localizations*.dart`. CI của pull request sẽ tự động
+kiểm tra tất cả ngôn ngữ, tạo mã bản địa hóa và xác minh việc tích hợp.
+
+Các ví dụ sau hiển thị cả định nghĩa trong ARB và nội dung người dùng thực sự thấy sau khi ứng dụng truyền giá trị.
+
+1. Chèn biến vào thông điệp
+
+   Định nghĩa ARB:
+
+   ```json
+   "welcomeUser": "Xin chào, {name}"
+   ```
+
+   Kết quả hiển thị: khi `name = An`, người dùng thấy “Xin chào, An”. Có thể đổi trật tự câu nhưng phải giữ `{name}`.
+
+2. Hiển thị nội dung khác nhau theo số lượng
+
+   Định nghĩa ARB:
+
+   ```json
+   "fileCount": "{count, plural, =0{Không có tệp} =1{1 tệp} other{{count} tệp}}"
+   ```
+
+   Kết quả hiển thị:
+
+   - `count = 0` → “Không có tệp”
+   - `count = 1` → “1 tệp”
+   - `count = 3` → “3 tệp”
+
+   `=0`, `=1` và `other` lần lượt biểu thị số lượng bằng 0, bằng 1 và các số lượng còn lại. Chỉ dịch phần chữ
+   hiển thị cho người dùng bên trong mỗi nhánh.
+
+3. Hiển thị nội dung khác nhau theo giá trị biến
+
+   Định nghĩa ARB:
+
+   ```json
+   "taskState": "{state, select, running{Đang chạy} paused{Đã tạm dừng} other{Không xác định}}"
+   ```
+
+   Kết quả hiển thị:
+
+   - `state = running` → “Đang chạy”
+   - `state = paused` → “Đã tạm dừng”
+   - Giá trị khác → “Không xác định”
+
+   `running`, `paused` và `other` là các giá trị do ứng dụng truyền vào nên không được dịch; chỉ dịch phần chữ
+   hiển thị trong dấu ngoặc theo sau chúng.
+
+## Phát triển flutter
+
+Đừng quên chạy `dart format ./ui/flutter` trước khi commit để giữ mã của bạn theo định dạng dart chuẩn.

+首先感謝您願意幫助我們改進並優化該項目，這份指南將會幫助您更好的參與 Gopeed 的開發。
+
+## 分支說明
+
+本項目只有一個分支，即 `main` 分支，如果您想要參與 Gopeed 的開發，請先 fork 該項目，再在您自己的 fork 中進行開發，開發完成後再開啟PR，以合併至 `main` 分支。
+
+## 離線開發
+
+建議使用 web 端進行開發與調試，首先啟動服務，使用指令 `go run cmd/api/main.go` 啟動 ，該服務默認連接埠為 `9999`，接著以 `debug` 模式啟動前端 flutter 項目即可。
+
+## 翻譯
+
+Flutter 翻譯檔位於 `ui/flutter/lib/l10n`，請以 `app_en.arb` 為來源範本，修改或新增
+`app_<locale>.arb`（例如 `app_de.arb` 或 `app_zh_TW.arb`）。每個語言都必須與英文範本包含相同的訊息 key。
+
+只翻譯訊息值，不要修改 `{count}`、`{name}` 等大括號中的變數名稱。以 `@` 開頭的中繼資料 key 不需要翻譯。
+提交時只需包含修改過的 ARB 來源檔，不需要產生或提交 `app_localizations*.dart`。PR 的 CI
+會自動驗證所有語言、產生國際化程式碼並檢查整合結果。
+
+以下範例同時列出 ARB 中填寫的訊息定義，以及程式傳值後使用者最終看到的內容。
+
+1. 在訊息中插入變數
+
+   ARB 定義：
+
+   ```json
+   "welcomeUser": "你好，{name}"
+   ```
+
+   最終顯示：當 `name = 小明` 時，顯示「你好，小明」。翻譯時可以調整整句話，但必須保留 `{name}`。
+
+2. 依數量顯示不同訊息
+
+   ARB 定義：
+
+   ```json
+   "fileCount": "{count, plural, =0{沒有檔案} =1{1 個檔案} other{{count} 個檔案}}"
+   ```
+
+   最終顯示：
+
+   - `count = 0` →「沒有檔案」
+   - `count = 1` →「1 個檔案」
+   - `count = 3` →「3 個檔案」
+
+   `=0`、`=1`、`other` 分別代表數量為 0、數量為 1 和其他數量。只翻譯各分支大括號內顯示給使用者的文字。
+
+3. 依變數值顯示不同訊息
+
+   ARB 定義：
+
+   ```json
+   "taskState": "{state, select, running{執行中} paused{已暫停} other{未知狀態}}"
+   ```
+
+   最終顯示：
+
+   - `state = running` →「執行中」
+   - `state = paused` →「已暫停」
+   - 其他值 →「未知狀態」
+
+   `running`、`paused`、`other` 是程式傳入的分支值，不能翻譯；只翻譯其後大括號內的顯示文字。
+

+
+Truy cập ✈ [Trang web chính thức](https://gopeed.com)
+
+![Ảnh chụp màn hình ứng dụng](_docs/img/ui-concept-en.png)
+
+## ✨ Tính năng chính
+
+- ⚡ **Tải xuống tốc độ cao** — kết hợp nhiều tác vụ, truyền HTTP phân đoạn qua nhiều kết nối và tải BitTorrent P2P để tận dụng tối đa băng thông.
+- 🧲 **Đa giao thức** — quản lý HTTP, HTTPS, BitTorrent, Magnet và ed2k trong một giao diện.
+- 🌱 **Bộ công cụ BT đầy đủ** — hỗ trợ khám phá Peer qua DHT, truyền tải uTP, Web Seed, chọn tệp, quản lý Tracker, xem Peer/mảnh và kiểm soát seed theo tỷ lệ hoặc thời gian.
+- 📋 **Quản lý tác vụ thực tế** — tạm dừng, tiếp tục, thử lại, thao tác hàng loạt, tìm kiếm, bộ lọc, danh mục và khôi phục khi khởi động.
+- 🪶 **Trải nghiệm native gọn nhẹ** — giao diện chính được Flutter kết xuất native. Không Electron. Không vỏ bọc WebView. Kích thước nhỏ hơn, ít tốn tài nguyên hơn và phản hồi nhanh hơn.
+- 💻 **Đa nền tảng** — Windows, macOS, Linux, Android, iOS, Web, Docker và QNAP.
+- 🎨 **Giao diện tùy biến** — hỗ trợ chế độ theo hệ thống, sáng, tối và 8 màu nhấn.
+- 📐 **Bố cục thích ứng** — danh sách tác vụ, điều hướng, cài đặt và màn hình chi tiết tự điều chỉnh cho điện thoại, máy tính bảng và cửa sổ desktop có thể thay đổi kích thước.
+- 🗣️ **Hơn 20 ngôn ngữ giao diện** — gồm tiếng Việt, tiếng Anh, tiếng Trung giản thể và phồn thể, tiếng Nhật, tiếng Hàn cùng nhiều ngôn ngữ khác.
+- 🌐 **Tích hợp trình duyệt** — gửi tải xuống từ Chrome, Edge, Firefox và các trình duyệt tương thích sang Gopeed.
+- 🧩 **Tiện ích JavaScript** — thêm nguồn tải từ nền tảng video, kho mô hình AI, lưu trữ đám mây và nhiều dịch vụ khác.
+- 🤖 **Tích hợp AI** — cung cấp giao diện MCP để kết nối với các AI Agent tương thích và tạo, kiểm tra hoặc quản lý tác vụ tải xuống bằng ngôn ngữ tự nhiên.
+- 🔌 **Giao diện mở** — REST API, CLI, Web UI có xác thực, webhook và script sau khi tải.
+- 🛠️ **Công cụ tích hợp** — Header/User-Agent tùy chỉnh, proxy, mirror GitHub, thông báo và tự động giải nén.
+
+## 🤖 Tích hợp AI
+
+Sau khi kết nối Gopeed với AI Agent, bạn có thể quản lý tải xuống bằng ngôn ngữ tự nhiên. Ví dụ, hãy nói với AI Agent:
+
+> Hãy tải xuống phiên bản Gopeed mới nhất dành cho Windows
+
+| Tool | Mô tả |
+| --- | --- |
+| `resolve_task` | Phân tích URL hoặc URI tải xuống và trả về thông tin tài nguyên cùng danh sách tệp trước khi tạo tác vụ. |
+| `create_task` | Tạo và bắt đầu tác vụ từ ID tài nguyên đã phân tích hoặc từ yêu cầu tải xuống trực tiếp. |
+| `list_tasks` | Liệt kê tác vụ và có thể lọc theo ID hoặc trạng thái. |
+| `get_task` | Lấy yêu cầu, tài nguyên, tùy chọn và tiến độ hiện tại của một tác vụ. |
+| `get_task_status` | Lấy trạng thái chạy rút gọn và tiến độ của từng tệp trong một tác vụ. |
+| `get_task_stats` | Lấy số liệu thống kê theo giao thức, gồm kết nối HTTP hoặc Peer và dữ liệu seed của BitTorrent. |
+| `pause_task` | Tạm dừng tác vụ. |
+| `continue_task` | Tiếp tục tác vụ đã tạm dừng hoặc bị lỗi. |
+| `delete_task` | Xóa tác vụ và có thể xóa cả các tệp đã tải xuống. |

+### 🧪 Gopeed 2.0.0 Beta
+
+Gopeed 2.0.0 hiện đang trong giai đoạn beta công khai, với giao diện được thiết kế lại, kiến trúc giao tiếp native kết nối trực tiếp ứng dụng desktop và di động với lõi Go qua FFI, trải nghiệm đa nền tảng nhất quán hơn, khả năng quản lý tác vụ được cải thiện, API linh hoạt hơn và khả năng tích hợp AI Agent qua MCP. Một số tính năng có thể vẫn chưa hoàn thiện hoặc chưa ổn định, vì vậy hãy dùng thử và gửi phản hồi nếu bạn gặp vấn đề.
+
+- [Tải Gopeed 2.0.0 Beta 1](https://github.com/GopeedLab/gopeed/releases/tag/v2.0.0-beta.1)
+
+Khi các tính năng và độ ổn định đáp ứng tiêu chuẩn phát hành, chúng tôi sẽ phát hành Gopeed 2.0.0 chính thức. Người dùng bản beta có thể nâng cấp trực tiếp lên bản chính thức, trong khi người dùng bản ổn định hiện tại sẽ không tự động được chuyển sang kênh beta.

+# 文件分类图标源物料
+
+此目录是 Gopeed 文件分类图标的唯一源物料目录，位于 Flutter 工程之外，不得加入 `ui/flutter/pubspec.yaml` 的 `assets` 配置。
+
+## 维护限制
+
+- 不要绕过 `$gopeed-file-category-icons` 技能直接修改、移动或批量替换这里的 SVG 与 manifest。
+- 需要调整图标时，必须配套使用该技能的安全区、码位兼容、字体生成和多尺寸预览流程。
+- 不要直接编辑生成的 `GopeedIcons.ttf` 或 `gopeed_icons.dart`。
+- 不要复用或重排 manifest 中已有的 codepoint。
+
+## 目录内容
+
+- `svg/`：24×24 的可编辑 SVG 源文件。
+- `manifest.json`：图标名称、SVG、稳定码位与产物路径的唯一映射。
+- `preview/`：生成的 16/20/24/32px 明暗预览，用于整套视觉审查。
+
+## 生成产物
+
+- Flutter 字体：`ui/flutter/assets/fonts/GopeedIcons.ttf`
+- Flutter 常量：`ui/flutter/lib/core/icons/gopeed_icons.dart`
+
+所有修改都应遵循：
+
+```text
+使用 $gopeed-file-category-icons 修改 SVG/manifest
+→ 重新生成完整 TTF 和 Dart 常量
+→ 检查多尺寸明暗预览
+→ 运行 Flutter 静态分析与测试
+```
