Migrate a legacy bl_info add-on to the Extensions Platform in three steps, with a before/after diff and the dual-format pattern. Use when the user has a bl_info dictionary in __init__.py, asks whether bl_info is deprecated or still supported, wants to publish to extensions.blender.org or ship an extension .zip, or sees warnings about legacy add-ons at install time. Targets 5.2 LTS; manifests work from 4.2.

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

# bl_info Migration to the Extensions Platform

## Trigger

Use this skill when the user:

- Has an existing add-on with a `bl_info = {...}` dictionary at the top of `__init__.py`
- Wants to publish to extensions.blender.org or distribute as a `.zip` for the Extensions Platform
- Asks "is bl_info dead?" or "do I have to migrate?"
- Sees a deprecation warning at install time about legacy add-ons
- Mentions `blender_manifest.toml`, "Install legacy Add-on", or "the new extension system"

## Is bl_info still supported?

Yes, with caveats.

- **In 5.2 LTS (current stable; 5.1 is prior stable)**: `bl_info` is supported as a fallback for legacy add-ons. The Edit > Preferences > Add-ons panel still has "Install legacy Add-on" and recognizes `bl_info` dicts.
- **For the Extensions Platform** (extensions.blender.org and the new add-ons UI): you need a `blender_manifest.toml`. `bl_info` is ignored.
- **Dual format** is officially recognized: ship a `blender_manifest.toml` and keep the `bl_info` dict. The platform reads the manifest; legacy installers read `bl_info`. Both code paths work without conditional logic.

How to install

The exact contents, by fingerprint
mdr add tmhsdigital/blender-developer-tools/bl-info-migration@sha256:2f38a832f7233f13

The line at the top of this page pins the label git:20261012.96b6076, 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.
