Which rune? Props: $props() | Bindable: $bindable() |
Computed: $derived() | Side effect: $effect() | State: $state()
Key rules: Runes are top-level only. $derived can be overridden
(use const for read-only). Don't mix Svelte 4/5 syntax.
Objects/arrays are deeply reactive by default.
<script>
let count = $state(0); // Mutable state
const doubled = $derived(count * 2); // Computed (const = read-only)
$effect(() => {
console.log(`Count is ${count}`); // Side effect
});
</script>
<button onclick={() => count++}>
{count} (doubled: {doubled})
</button>

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionsvelte-runesExecute the skills CLI command in your project's root directory to begin installation:
Fetches svelte-runes from spences10/svelte-skills-kit and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate svelte-runes. Access via /svelte-runes in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.
