🚨🚨🚨
PSA: if you were using the Svelte Claude marketplace: we've renamed the repo which means that unfortunately you would not get updates if you added the marketplace as `sveltejs/mcp`.
Please remove the old marketplace and re-install `sveltejs/ai-tools`...it comes with a surprise 👀
🚨🚨🚨
Thanks!
👋 I'd like to to LocalFirst but not sure I can make it. Are the tickets refundable and/or transferable?
We released a new version of the svelte opencode plugin. It now ships with all the available skills and automatically adds them to your opencode skills (require last version of both)
If you want you can disable the MCP or the Skill by creating a `svelte.json` next to your `opencode.json` config 🧡
🙇 Let's make AI write Svelte even better! File an issue for tasks where LLMs are struggling to help us fix them!
If you haven't tried Claude / Claude Code yet, here's a few referral codes to get a free week. Have fun and build something awesome!
claude.ai/referral/3eB...
the anthropic drama (tl;dr they blocked third party tools from using claude code subscriptions) is a useful reminder that you use LLMs at the pleasure of the companies providing them
sounds obvious but despite all the AI discourse, i don't see a lot of people talking about the consequences of this
We released a Svelte Skill! It will teach your agent to use the svelte CLI to invoke the same tools as the MCP! We also released a subagent so that docs and iterations with the autofixer don't take up precious context!
And you can get all of that easily because the repo is now a Marketplace! 🧡
Finally, opencode supports MCP prompts (this was the PR I was waiting to get released)! I already switched to it as my daily driver, now it will be much better (prompts are a powerful MCP primitive and I use it every time with the svelte MCP).
Next: resources! I already have them working locally! 😎
Thanks for trying it out! I think the cost calculations weren't working right but after merging the below PR they should work (more or less) correctly. The main challenge is doing things in a provider-agnostic way.
github.com/sveltejs/ai/...
Works anywhere where you can use the Pro/Max plans!
🧑💻 If you're using Claude Code on a Mac, the Claude Usage app lets you easily keep track of your usage from the menu bar, and it can even notify you when you're getting close to your limit. Free and open source at github.com/hamed-elfayo...
Work on SvelteBench 2.0 is in progress! This time we're working on making it fully agentic and to support the official Svelte MCP! If you have ideas for the next version, please share them at github.com/sveltejs/ai/... - some early screenshots below.
👀 The first model that writes perfect Svelte 5 code is here! In the video below you'll find out which one and see the scores for frontier models among all the big providers like Google, OpenAI and Anthropic! #svelte #javascript #ai

We have a Julebord on the 15th Dec in case you want to quickly meet some people here, details in Discord. cc @kevinak.se
🎙️ Just published a new episode of Svelte Radio: Custom Renderers for Svelte with Paolo Ricciuti . Have a listen:
Wow, the future is here 😂
The benchmark is open source Rodrigo, have a look! :-)
👀 The first AI model from OpenAI that can properly write Svelte 5 is here - welcome GPT 5.2! All results at khromov.github.io/svelte-bench...
💫 Putting the finishing touches on my next video - tomorrow we'll find out how AI models have been improving at writing Svelte 5 code and which model has gotten a perfect store on the Svelte LLM benchmark! #ai #svelte
Anthropic enabled Opus 4.5 for all Claude Code users (including Pro!) and you can set /model opusplan to use Opus 4.5 only for Plan mode and Sonnet 4.5 for execution to make your quota last longer!

If you are running projects on Next.js, you probably want to immediately upgrade them since a vulnerability with CVSS 10.0 (highest possible) was just disclosed in the RSC implementation, meaning the door is essentially wide open to hack your sites.

Guys I'm not making this up...I asked Claude, ChatGPT, Gemini and Grok what frontend framework they would pick if they only could pick the one they would enjoy writing more.
They ALL said Svelte 🧡
Do your LLM a favor, switch to Svelte 🧡
A historic first today as Opus 4.5 scores 100% on SvelteBench - the first model to do so. We're hard at work on the next version of SvelteBench that will use an agentic approach, if you have feedback, submit it here: github.com/khromov/svel... #svelte #ai
pretty excited about this feature (thanks @ottomated.net!). dealing with file uploads can be a bit of a pain — the way it works normally is that you (or your framework) does `await request.formData()` to get a FormData object. but it has to buffer every file into memory first. that's a problem!
🤖 Gemini 3.0 SvelteBench results are out! Gemini 2.5 was already great and 3.0 improves on the already excellent scores. All results at khromov.github.io/svelte-bench... #svelte #ai
My quota limit for quota limits has been exceeded. 🙈 Just #AWS things!
🎧 A couple of weeks ago I was a guest on the Svelte Radio podcast to talk about Svelte AI benchmarking and the brand new Svelte MCP server. Check it out in case you missed it! #svelte #javascript

If you're not tired of hearing about Svelte and AI I'm was recently on the Svelte Radio podcast!
Interested in hearing about Svelte and AI? Tomorrow we're releasing an episode of Svelte Radio with @khromov.se to talk about Svelte Bench and the new Svelte MCP server that was recently released.
We also talk about how LLMs always want to write React
Stay tuned!
