The instructions your model reads when the skill loads.
Splash is Makepad 2.0's core runtime UI scripting language, released February 12, 2026. It replaces the old compile-time live_design! macro system with a runtime script_mod! macro that enables hot reload, streaming evaluation, and AI-first code generation.
Every Splash script starts with a use import and is embedded in Rust via the script_mod!{} macro:
use makepad_widgets::*;
app_main!(App);
script_mod! {
use mod.prelude.widgets.*
// let bindings, functions, state, and UI definitions go here
startup() do #(App::script_component(vm)){
ui: Root{
main_window := Window{
window.inner_size: vec2(800, 600)
body +: {
// UI content
}
}
}
}
}
