-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.

-//
-// Usage (from ui/flutter):
-//   dart run ../../.github/workflows/scripts/check_l10n.dart
-//
-// What it checks:
-// - Every ARB file uses the repository's canonical two-space JSON formatting.
-// - Every app_<locale>.arb file declares the matching @@locale value.
-// - Message values are not empty (warning only).
-// - Every locale has the same message keys as app_en.arb (warning only).
-// - Every translation preserves the placeholder variables used by app_en.arb
-//   (warning only).
-//
-// Notes:
-// - This script does not judge translation quality.
-// - It does not generate localization code or fully parse ICU MessageFormat.
-//   `flutter gen-l10n` runs immediately afterwards in CI to validate ICU syntax
-//   and generate app_localizations*.dart.
-// - The script exits with a failure only for malformed JSON, invalid ARB
-//   formatting, or a mismatched @@locale value. Translation completeness is
-//   reported as warnings; generation and analysis remain the compile-time gate.

 ## Translation
 
-Flutter translations are ARB files in `ui/flutter/lib/l10n`. Use `app_en.arb` as the source template,
-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.
+The internationalization files of Gopeed are located in the `ui/flutter/lib/i18n/langs` directory.
+You only need to add the corresponding language file in this directory.
 
-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.
-
-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:
-
-   ```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.
+Please refer to `en_us.dart` for translation.
+words prefixed with `@` are not meant to be translated.

 ## 🚀 Introduction
 
-Gopeed (short for **Go Speed**) is a fast, modern, free, and open-source download manager built with Go and Flutter. It supports HTTP, HTTPS, BitTorrent, magnet links, and ed2k on desktop, mobile, and the web.
+Gopeed (full name Go Speed), a high-speed downloader developed by `Golang` + `Flutter`, supports (HTTP, BitTorrent, Magnet, ED2K) protocol, and supports all platforms. In addition to basic download functions, Gopeed is also a highly customizable downloader that supports implementing more features through integration with [APIs](https://gopeed.com/docs/dev-api) or installation and development of [extensions](https://gopeed.com/docs/dev-extension).
 
-Beyond core download management, Gopeed offers browser integration, JavaScript extensions, a REST API, a CLI, and a self-hosted web UI for customization and automation.

 ## 👨‍💻 Development
 
-Gopeed consists of a Flutter front end and a Go back end. They communicate over HTTP, using Unix sockets on Unix-like systems and TCP on Windows.
+This project is divided into two parts, the front end uses `flutter`, the back end uses `Golang`, and the two sides communicate through the `http` protocol. On the unix system, `unix socket` is used, and on the windows system, `tcp` protocol is used.
 
-> The front-end source is located in the `ui/flutter` directory.
+> The front code is located in the `ui/flutter` directory.

 ## 🚀 Giới thiệu
 
-Gopeed (viết tắt của **Go Speed**) là trình quản lý tải xuống nhanh, hiện đại, miễn phí và mã nguồn mở, được xây dựng bằng Go và Flutter. Gopeed hỗ trợ HTTP, HTTPS, BitTorrent, Magnet và ed2k trên máy tính, thiết bị di động và Web.
+Gopeed (tên đầy đủ Go Speed), một công cụ tải xuống tốc độ cao được phát triển bởi `Golang` + `Flutter`, hỗ trợ giao thức (HTTP, BitTorrent, Magnet, ED2K) và hỗ trợ tất cả các nền tảng. Ngoài các chức năng tải xuống cơ bản, Gopeed còn là một công cụ tải xuống có thể tùy chỉnh cao cho phép triển khai thêm tính năng thông qua việc tích hợp với [APIs](https://gopeed.com/docs/dev-api) hoặc cài đặt và phát triển các [tiện ích mở rộng](https://gopeed.com/docs/dev-extension).
 
-Ngoài việc quản lý tải xuống hằng ngày, Gopeed còn hỗ trợ tích hợp trình duyệt, tiện ích JavaScript, REST API, CLI và Web UI có thể tự lưu trữ để mở rộng và tự động hóa quy trình.

-## ✨ 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. |
