Thanks @simonwillison.net, always enjoy your content. I also really like HTML tools. Thank you for all the resources!

Was inspired to share them:

Want to try vibe coding without production software complexity?

HTML tools are the perfect playground for LLM-assisted development.

Single files, no deployment, no dependencies. Just experiment and iterate.

Thanks @boscolo.co - I wish I had come up with “coding with no pants”, that’s an awesome title!

AI coding assistants index your entire codebase, including credentials and customer data.

Each AI coding tool handles security differently.

I wanted portable AI tools you can spin up by describing them, not hand-coding MCP servers.

Describe what you want once. A registry turns that into MCP servers and CLIs that any AI coding assistant can use.

One definition, every assistant and format you need.

When AI summarizes customer reviews, it often invents names and numbers that look real but aren’t.

We saw this in weekly reports across Google, DoorDash, Yelp. Strong insights, wrong facts.

Fix: teach AI to verify its own work, not just summarize data.

As teams adopt AI coding tools, they face familiar challenges: maintaining code quality and consistency with team standards. The same principles that help developers write better code can also guide AI tools.

Billions of requests across MCP servers deployed on Vercel, including Zapier, Solana, and our own.

A key insight: wrapping your API in an MCP server isn't enough.

I met Mikeal at the first NodeConf, which he helped organize. He’s the earliest and most vibrant memory I have of the excitement and community he helped form during the early days of Node.js, and as a strong voice in the JavaScript ecosystem. Rest in peace Mikeal.

Hey Doug, I’m curious about sampling.

Which MCP clients support this?

(My understanding is Claude Desktop doesn’t yet support)

If you are trying to use OpenAI Files API in Node.js and running into duplex and other errors uploading files:

You will fall down a lot of rabbit holes on the internet and with LLMs.

Instead, `npm add undici` to update Node to the latest version of `fetch`.

Congrats to @ngerakines.me for a new version of @smokesignal.events.

This is a very major rewrite, and also open sourcing of the whole codebase - with more features yet to come!

Events connect people - the exact kind of thing that should be available on an open protocol.

I'm so excited for this to go out. Over the past several months, the Smoke Signal app has been rewritten and refactored to support some big (currently in-development) features and have plenty of room to grow.
