Svelte Runes

If you're working with Svelte 5's new reactivity system, this skill gives you quick reference for all the runes: $state, $derived, $effect, $props, and $bindable. It includes a compact decision tree for choosing the right one, covers the top-level-only constraint, and points you to references on migration gotchas from Svelte 4. The real value is in preventing common mistakes like mixing old and new syntax or misunderstanding that $derived can be reassigned unless you use const. It also reminds you about the new onclick syntax and snippet-based layouts, which trip up a lot of people during migration.
