kde-plasmoid SKILL.md skillA
kde-plasmoid from codeatcode/oss-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add codeatcode/oss-ai-skills/kde-plasmoid@v2.0.0Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use when building KDE Plasma 6 widgets with a Python backend - plasmoid structure, metadata.json, QML UI, configuration system, plasmapkg2 packaging, KDE Store submission, or plasmoid testing and debugging.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Objective:** Use this skill to reduce plasmoid-load failures, metadata-schema rejections, QML-binding-loop freezes, and packaging errors by enforcing metadata-discipline, QML-lifecycle rules, and plasmapkg2-verification patterns below.
# KDE Plasmoid Development with Python
Build Plasma 6 widgets with Python backend + QML UI.
**Important**: Native Python Plasmoids (PyKDE4/PyKDE5) are deprecated in Plasma 6. Use QML UI + Python backend via QObject.
See `references/plasmoid-structure.md` for complete structure, metadata.json schema, and dependency listings.
## Python Backend Rules
**Do subclass QObject** because QML requires QObject-derived types for property/signal exposure.
**Do emit signals after property changes** because QML bindings only update on signal emission:
```python
dataUpdated = Signal()
@Property(str, notify=dataUpdated)
def data(self):
return self._data
@data.setter
def data(self, value):
if self._data != value:
self._data = value
self.dataUpdated.emit() # ← Required for QML update
```
**Do use @Slot for QML-callable methods** because unmarked methods may fail cross-language calls.

How to install
mdr add codeatcode/oss-ai-skills/kde-plasmoid@sha256:8e29b903005ec9f4The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
