What svelte-development does

This skill injects Svelte 5 guidelines directly into the agent context. It instructs the assistant to use modern runes such as $state, $derived, $effect, and $props rather than legacy syntax.

The reference material covers single-file component anatomy, scoped CSS, event dispatching, and slot projection. Generating code with these patterns breaks immediately on projects configured for older Svelte versions lacking runes support.

What it helps with

  • manage reactive local state using $state and $derived runes
  • define typed component interfaces with the $props rune
  • handle lifecycle logic and timers with cleanup in $effect
  • build isolated UI components with scoped styles and slots

Example prompts for the agent

  • Create a counter component using Svelte 5 runes with doubled count logic.
  • Build a modal component featuring named slots and backdrop click handling.
  • Define a TypeScript card component that accepts typed properties via $props.
