Svelte 5 runes, snippets, and SvelteKit patterns for modern component development.
Works with
Covers all Svelte 5 runes ($state, $derived, $effect, $props, $bindable, $inspect) with reactive state and computed value patterns
Explains snippets syntax ({#snippet}, {@render}) as the replacement for slots and slot props
Includes event handling migration from on: directives to onclick handlers and callback props, plus SvelteKit load functions and form actions
Provides TypeScript typing for props,
AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionsvelte5-best-practicesExecute the skills CLI command in your project's root directory to begin installation:
Fetches svelte5-best-practices from ejirocodes/agent-skills 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 svelte5-best-practices. Access via /svelte5-best-practices 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.

|---|---|---|
| Runes | $state, $derived, $effect, $props, $bindable, $inspect | runes.md |
| Snippets | Replacing slots, {#snippet}, {@render} | snippets.md |
| Events | onclick handlers, callback props, context API | events.md |
| TypeScript | Props typing, generic components | typescript.md |
| Migration | Svelte 4 to 5, stores to runes | migration.md |
| SvelteKit | Load functions, form actions, SSR, page typing | sveltekit.md |
| Performance | Universal reactivity, avoiding over-reactivity, streaming | performance.md |
<script>
let count = $state(0); // Reactive state
let doubled = $derived(count * 2); // Computed value
</script>
<script>
let { name, count = 0 } = $props();
let { value = $bindable() } = $props(); // Two-way binding
</script>
<script>
let { children, header } = $props();
</script>
{@render header?.()}
{@render children()}
<!-- Svelte 5: use onclick, not on:click -->
<button onclick={() => count++}>Click</button>
<script>
let { onclick } = $props();
</script>
<button onclick={() => onclick?.({ data })}>Click</button>
let without $state - Variables are not reactive without $state()$effect for derived values - Use $derived insteadon:click syntax - Use onclick in Svelte 5createEventDispatcher - Use callback props instead<slot> - Use snippets with {@render}$bindable() - Required for bind: to workPromise.all for parallel requestsPrerequisites

💡 Pro Tips
✓ Use when
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid when
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
