Django Expert skill: what it does and how to install it

What it does. Guides Django 5.0 and Django REST Framework implementation from model design and migrations through serializers, viewsets, permissions, JWT authentication and tests. It emphasises indexed fields, select_related and prefetch_related, environment-based secrets, validation and endpoint checks.

When to use it. Use for Django web applications or REST APIs, including models, ORM queries, admin customisation and authentication. It does not permit skipped migrations, unvalidated input, unprotected endpoints or unparameterised raw SQL.
