+# AGENTS.md
+
+Guidance for AI agents working in this repo. Verified against `CMakeLists.txt`,
+`package/metadata.json`, and the installed macro file at
+`/usr/lib/x86_64-linux-gnu/cmake/DDEShell/DDEShellPackageMacros.cmake`.
+
+## What this is
+
+A **pure-QML dde-shell applet** (deepin desktop shell panel widget). There is no
+C++ and no `.so` plugin — the entire applet is `package/main.qml` +
+`package/metadata.json`, installed as a data package via dde-shell's CMake macros.
+
+- Applet ID: `space.jokul.JNetApplet`.
+- Root element of `main.qml` must be `AppletItem` from `import org.deepin.ds 1.0`.
+
+## Build & install
+
+Requires the `DDEShell` CMake package (from the `dde-shell` dev package) at configure
+time. Standard flow:
+
+```sh
+cmake -B build
+cmake --build build
+sudo cmake --install build   # -> /usr/share/dde-shell/space.jokul.JNetApplet/
+```
+
+`cmake --install` needs `sudo` because the default `DDE_SHELL_PACKAGE_INSTALL_DIR`
+is `/usr/share/dde-shell` (a CMake CACHE variable on this system). For a user-local
+install instead:
+
+```sh
+cmake -B build -DCMAKE_INSTALL_PREFIX=$HOME/.local
+cmake --build build && cmake --install build   # -> ~/.local/share/dde-shell/space.jokul.JNetApplet/
+```
+
+There is no test, lint, typecheck, or CI target. Verification is manual: install,
+then restart `dde-shell` (it discovers applets by scanning the install dir for
+`metadata.json`). The build also stages a copy at `build/packages/space.jokul.JNetApplet/`
+for previewing the QML without installing.
+
+## Identifier correspondence (keep in sync when renaming)
+
+| Where | Field | Value |
+|---|---|---|
+| `CMakeLists.txt` | `ds_install_package(PACKAGE …)` | `space.jokul.JNetApplet` |
+| `package/metadata.json` | `Plugin.Id` | `space.jokul.JNetApplet` |
+
+The CMake `PACKAGE` becomes the install subdirectory name; `Plugin.Id` is the runtime
+identifier. They don't technically have to match, but every official dde-shell applet
+keeps them identical — treat them as required to match.
+
+`Plugin.Url` (`main.qml`) is a path **relative to `package/`**, not an identifier.
+Keep it pointing at the entry QML.
+
+## Required metadata fields (QML applet)
+
+`metadata.json` must contain `Plugin.Version`, `Plugin.Id`, and `Plugin.Url`. The
+current file is complete — don't drop any. (`Plugin.Url` is omitted only for
+widget-based, non-QML plugins.)
+
+## Package layout is fixed by the macro
+
+`ds_install_package` reads `package/` relative to `CMAKE_CURRENT_SOURCE_DIR` by
+default (overridable via `PACKAGE_ROOT_DIR`, not used here). Keep the directory named
+`package/` with `metadata.json` at its root.
+
+## Adding translations (not yet set up)
+
+If i18n is needed, use the `ds_handle_package(PACKAGE <id>)` macro from the same
+DDEShell package. It expects `.ts` files at `translations/<id>_<lang>.ts` and
+installs compiled `.qm` to `${DDE_SHELL_TRANSLATION_INSTALL_DIR}/<id>/translations/`.
+Do not invent a different translation workflow.
+
+## Conventions
+
+- QML files carry SPDX headers (`SPDX-FileCopyrightText` +
+  `SPDX-License-Identifier: LGPL-3.0-or-later`). Preserve on new/edited QML files.
+- Default branch is `master` (not `main`).
