Umbraco Property Value Preset
If you're building Umbraco backoffice extensions and need to set default values when editors create new content, this handles the boilerplate. It fetches the latest official docs, asks what property editor you're targeting and what default you want (static, dynamic, or async), then generates both the manifest and the preset API implementation. The skill covers the full pattern including weighted presets that chain together, config-based defaults, and targeting by schema alias. Useful when you want sensible starting values without forcing editors to fill in the same fields repeatedly. The examples are minimal but complete, which is how this kind of utility code should be.

Umbraco Property Value Preset
What is it?
Property Value Presets provide default values when users create new content. They use an API to supply preset values for specific property editors, enabling streamlined content creation with sensible defaults. Multiple presets can work together using the weight property to progressively modify values.
