This is a new skill that aims to collect a few best practices about writing svelte... I approached this as if I were teaching someone how to write good svelte code.

Tested it with our svelte evals and it seems to do even better than the MCP (I guess in tandem with it, it could be even better).

We should also write a svelte-ssr-bestpractices skill that focus on how to best use sveltekit instead but for the moment we can start with this.

You can try out the skill by doing
