I was part of the early alpha for this, they opened a beta wait list today. The thing that is different here is that they remove 99.9% of the friction to create agents, the target user group is not a user who can run Claude Code and install their app on some service, it is everyone else who couldn't be bothered to worry about plans, keys, domain names, datatabes, etc.

You talk to a master agent (Sidekick) describing the app you want, and it creates it for you, batteries included (a lot of tools, which are vetted MCP servers and skills, a database, cron-jobs, and a hosting environment where your apps live). The tools connect to many things such as email, slack, weather, sports, news, web, and your agents can do all sorts of things.

What is the lifetime of the Ray workers, or, in other words, what is the scalability / scale-to-zero story that makes this serverless?

The small city of São Paulo (~22M people) has also banned billboards since 2007, and life goes on.

Peter, how does this compare to Azure Durable Functions? (Say, for the sake of argument, that you are comparing the Python version of both) Are there things that fundamentally you can do in one and not in the other?

Were they aware in this study that they were being evaluated in their ability to know if they were being evaluated ;)

I may be missing something, but in addition to this threat of prompt injection, you also have to trade trusting the arbitrary MCP server for trusting MCP Defender.

In the default mode, the app will interpose on the communication between, say, Claude, and a local MCP server. It will send the contents of the message (which may include the very sensitive information it is trying to protect) to a remote LLM, which you have to trust. The "scans" will be stored on a log on the server. Not to mention the potential extra delay for every MCP exchange?

This may be more secure, but is it really?

I was using Pocket to save articles to listen to in the car, with their ok TTS feature. Does anyone know of an easy solution that allows me to click to save an article, and then have it automatically on an app on my phone so I can listen while I drive?

This was an interesting quote from the blog post: "There is one silly technique I discovered to allow a LLM to improve my writing without having it do my writing: feed it the text of my mostly-complete blog post, and ask the LLM to pretend to be a cynical Hacker News commenter and write five distinct comments based on the blog post."
