Addon Scaffolding (Extensions Platform)

Trigger

Use this skill when the user:

• Wants to start a new Blender add-on
• Mentions bl_info, blender_manifest.toml, "extension", "register_classes_factory"
• Is migrating an existing add-on from the legacy bl_info format to the Extensions Platform
• Is unsure which file layout or registration pattern to use for Blender 4.5+ or 5.x

Required inputs

• Add-on name and short id (snake_case for the manifest id, human-readable name)
• Target Blender versions (defaults to blender_version_min = "4.5.0" so the add-on works on 4.5 LTS and 5.1)
• Maintainer string (Name <email@example.com> form)
• License SPDX identifier (SPDX:MIT, SPDX:GPL-2.0-or-later, etc.)

The Extensions Platform format (5.x default)
