Generic plugin system for Python applications. Auto-discovery, validation, fault tolerance. Zero dependencies (Python stdlib only).
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.

# Plugin System
Fehlertolerantes Plugin-System fuer Python-CLI-Anwendungen.
Ein fehlerhaftes Plugin stoppt niemals den Rest der Anwendung.
## Kernfeatures
- **Auto-Discovery:** Findet Plugins automatisch in einem Verzeichnis
- **Validierung:** Prueft `name`, `version`, `execute()` auf jeder Plugin-Klasse
- **Fehlertoleranz:** Defekte Plugins werden geloggt aber nicht geladen
- **Zero Dependencies:** Nur Python-Standardbibliothek
## Dateien
```
scripts/
plugin_system.py Kern: PluginBase (ABC) + PluginManager
cli_demo.py Demo-CLI mit argparse
test_plugin_system.py 16+ Unit-Tests
examples/
hello.py Hello-World Plugin
calculator.py Rechner-Plugin
systeminfo.py System-Info Plugin
```
## Schnellstart
### 1. Plugin erstellen
```python
from plugin_system import PluginBase
class MeinPlugin(PluginBase):
name = "MeinPlugin"
version = "1.0.0"
def execute(self, *args, **kwargs):
return {"status": "ok", "message": "Hallo!"}
```
### 2. PluginManager nutzen
```python
from plugin_system import PluginManager
…Read the whole file at its exact version.
How to install
mdr add ellmos-ai/skills/plugin-system@sha256:a2fea4a34859b7d2The line at the top of this page pins the label v1.0.0, 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.
