Use this skill for anything Jx — the Python/Jinja2 component library. Covers BOTH (a) library mechanics and integration AND (b) authoring production-ready UI components. Trigger this skill on any mention of Jx, `.jx` files, "Jinja components" in a Python web app context, or requests to build/create UI components for such an app.

Use when building features, adding resources, writing controllers/models/forms/views, or working with addons (auth, storage, i18n, channels) in a Proper web framework application. Also use when the user asks about Proper framework conventions or patterns.

Build, render, and validate web forms with the Formidable Python library. Use when the user works with `formidable as f`, subclasses `f.Form`, uses fields like `f.TextField`, `f.NestedForms`, `f.FormField`, or asks how to render/validate/save a form, integrate with an ORM, or handle nested/dynamic forms.
