What problem does it solve?

Building robust, performant, and secure server-side interactions in SvelteKit can be complex, involving data validation, caching, and optimistic UI updates. This Skill simplifies the development, auditing, and review of SvelteKit remote functions, ensuring best practices are followed and common pitfalls avoided.

Core Features & Use Cases

• SvelteKit Integration: Provides guidance on query, command, form, and prerender functions for seamless client-server communication.
• Optimistic UI & Batching: Explains how to implement single-flight optimistic mutations and batch multiple queries to enhance user experience and performance.
• Validation & Security: Emphasizes validating every argument with a Standard Schema to prevent security vulnerabilities and ensure data integrity.
• Use Case: When developing a new feature in SvelteKit that requires server-side data manipulation, use this Skill to ensure your remote functions are correctly implemented with validation, optimistic UI, and efficient data fetching, reducing development time and preventing bugs.

Quick Start
