decompose-component

This skill should be used when the user is creating or modifying a Decompose component, mentions "ComponentContext", "retainedInstance", "stateKeeper", "instanceKeeper", "InstanceKeeper", "MutableValue", "Value<", component lifecycle, state preservation, instance retaining, back button handling in a component, or when writing a class that implements or extends a Decompose component interface. Also applies when the user asks how to structure a component, how to keep state across config changes, how to implement a ViewModel equivalent with Decompose, or how to handle the back button in a component.
