feat: claude skill + marketplace

[paoloricciuti]

This adds a svelte 5 skill that you can download manually to put in Claude code OR Claude desktop/web, but also makes this repo a Claude marketplace/plugin.

This will ease the experience of sharing the skill and the MCP server.

I've created the skill with the claude-skill-creator aided by the svelte MCP server (so meta) but I've reviewed it manually and found it pretty good... I would appreciate some extra review (and possibly I would love for as much people as possible to actually try the skill disabling the MCP server to see if it's actually working).

If you want to try the skill you can download it pre-zipped here

I love the idea of having an official Svelte Skill!
One suggestion: I think more guidance on function bindings would be helpful. In my experience, LLMs still frequently misuse the $effect rune—there are cases where function bindings are the better pattern (e.g., input validation and transformation).
It might be worth adding:

Common $effect antipatterns to avoid
Recommended alternatives (particularly function bindings) for those cases

Also, once async and remote functions graduate from experimental status, it would be great to have an agent skill that guides migration to async Svelte and remote functions.

Very cool PR! I am a bit skeptical to essentially adding a manual condensed version of the docs into the skill. I think rather than putting these in markdown files in the mcp repo it would be better to add instructions for the LLM which sections to fetch using the npx commands, to avoid duplicating the effort between normal docs, condensed docs, and the skill....

[khromov]

instruct the LLM to execute MCP calls with the agent

How?

[paoloricciuti]

Just by saying it use the agent lol
