Create MoviePilot Plugin

Use this skill to build or revise MoviePilot plugins that can be developed from a local plugin source and installed into the running MoviePilot instance.

Ground Truth

• Host plugin contract: app/plugins/__init__.py, especially _PluginBase.
• Host plugin discovery, local source sync, install, reload: app/runtime/extensions/plugin_manager.py and app/adapters/external/market.py.
• Host plugin endpoints, API auth, static files, remotes, and sidebar nav: app/api/endpoints/plugin.py.
• Local development note: docs/development-setup.md.
• Plugin repository conventions: MoviePilot-Plugins uses plugins.v2/ with package.v2.json for V2 plugins; legacy or cross-generation entries may use plugins/ with package.json.
• When working in or from MoviePilot-Plugins, read its README.md, docs/Repository_Guide.md, and docs/V2_Plugin_Development.md. For scenario-specific extensions, read the matching docs/faq/*.md.
