Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install svelte-5-coding-practices

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent applies Svelte 5 rules to each component or module: reactivity with $state, $derived and $effect, props, events, loops, styling and context. It draws on detailed references for edge cases.
