Best practices for writing Blender Python add-ons using the bpy API, covering operators, panels, properties, registration, and API-safe scripting. Use when creating a Blender add-on, defining bpy.types.Operator or Panel classes, registering PropertyGroup settings, writing register()/unregister() functions, working with bmesh, or debugging add-ons in Blender's Python console.
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
# Blender Python Add-on Development This skill covers building Blender add-ons with the `bpy` API, including add-on structure, operators, panels, properties, safe scene manipulation, and testing across Blender versions. ## Workflow for Building a Blender Add-on 1. **Scaffold the add-on** — Create a package with `__init__.py` as the entry point, and a `blender_manifest.toml` (Blender 4.2+ extensions) or `bl_info` dict (legacy add-ons) describing name, version, and supported Blender version. 2. **Define data** — Create `PropertyGroup` classes for grouped settings and register them on the appropriate ID type (e.g., `bpy.types.Scene.my_addon = PointerProperty(type=MyAddonSettings)`). 3. **Implement operators** — Subclass `bpy.types.Operator` for each user action; implement `poll()` for availability, `invoke()` for interactive setup, and `execute()` for the actual work. 4. **Build UI panels** — Subclass `bpy.types.Panel` to expose operators and properties in the appropriate editor (3D viewport sidebar, properties editor, etc.). …

How to install
mdr add mindrally/skills/blender-python-addon@sha256:ab09442134397ddcThe line at the top of this page pins the label git:20261008.7682ca7, 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.
