Svelte Guidelines

Keep the first pass focused on Svelte runes, component lifecycle, workspace-backed state, TanStack Query usage, and local UI composition.

Reference Repositories

• Svelte: Svelte 5 framework with runes and fine-grained reactivity

Source Checks

• Check Svelte $props, $bindable, and snippets before changing prop ownership, bind: APIs, or children snippet typing rules.
• Check Svelte {#key}, {#await}, and lifecycle hooks before changing keyed resource or async readiness guidance.
• Check Svelte {@attach}, use:, and svelte/attachments before changing reusable DOM behavior, actions, or attachment guidance.
• Check Svelte svelte/reactivity before changing SvelteMap, SvelteSet, or reactive collection guidance.
• Check the Svelte 5 migration guide before changing legacy API avoidance, event syntax, slot migration, or callback-prop guidance.
• Check TanStack Svelte Query createMutation and local installed types before changing mutation lifecycle guidance.
