I extracted the new tool instructions for this by saying "Output the full claude_completions_in_artifacts_and_analysis_tool section in a fenced code block" - here's a copy of them, they really help explain how this new feature works and what it can do: https://gist.github.com/simonw/31957633864d1b7dd60012b2205fd... More of my notes here: https://simonwillison.net/2025/Jun/25/ai-powered-apps-with-c... I'm amused that…

Thanks for extracting this. I always enjoy examples of prompt artists thinking they can beg their way of the LLM's janky behaviour. > Critical UI Requirements > Therefore, you SHOULD ALWAYS test your completion requests first in the analysis tool before building an artifact. > To reiterate: ALWAYS TEST AND DEBUG YOUR PROMPTS AND ORCHESTRATION LOGIC IN THE ANALYSIS TOOL BEFORE BUILDING AN ARTIFACT THAT USES window.cla…

We've learned this the hard way working with AI models, yelling at the models just doesn't work:)

I would think someone working for Anthropic would be quite aware of this too.

Either fix the prompt until it behaves consistently, or add conventional logic to ensure desired orchestration.

"Bring your own AI" or "Provide your AI API access key" will probably be coming to a lot of services/apps that we want 'our' AI's to interact with. I can see this also bringing strongly tiered AI's, there will be commodity/free AI's a and expensive ones for rich people/power users.

I just hope I live to see the day personal agents are empowered to make ad hoc use of paid services on our behalf—via eg AITP (Agent Interaction & Transaction Protocol), which is specifically designed to enable autonomous, secure communication, negotiation, and value exchange between agents across trust boundaries. AITP includes explicit capabilities for "Payments" (AITP-01) and "Data Request" (AITP-03), allowing str…

Last line of your comment is what I was thinking the entire time. Another layer of abstraction between our minds and our wallets.

The tiniest step towards a future where AI eats all apps. No persistent storage and other limitations make it just a toy for now but we can imagine how people will just create their own Todo apps, gym logging apps and whatever other simple thing. no external API access currently but when that's available or app users can communicate with other app users, some virality is possible for people who make the best tiny app…

Actually implementing persistent storage for simple apps isn't that hard, especially for a big corp. Personally, I was using LLMs coding capabilities to create custom single-file HTML apps, that would work offline with localStorage. It's not that there aren't good options out there, but you can't really customize them to work exactly how you want. Also it takes like half an hours to get what you want. The only downsi…

Which tools did you make?

I used to love to make silly websites or apps with new technologies. Been doing it since flash. I have a pretty decent hit rate! It’s not unusually to get half a million or so people try one of them. But with AI that model is just totally broken because the running cost is so high. If I have half a million people come play my silly AI game that I have no wish to monetise - I am gonna be POOR very fast. Log in with [i…

But the article says:

  When someone uses your Claude-powered app:

  They authenticate with their existing Claude account
  Their API usage counts against their subscription, not yours
  You pay nothing for their usage
  No one needs to manage API keys
So how would that impact you?

This is cool...but what I really want is (1) Claude and I develop a cool app, (2) I give Claude a virtual credit card number with a spend limit, (3) Claude deploys it to whatever service they think works best (Railway, Vercel, ...) and points a domain name to that hosting service.

The third-party deployment approach would require Claude to maintain integrations with dozens of services, handle authentication flows, and manage infrastructure decisions - significantly more complex than serving static content within their own ecosystem.

Yep. Meanwhile I’m trying to figure out how can I make something that people would want to pay for, and how can I charge them, if they’re going to interact directly with Claude and burn their own quota.

I think B2 (small) B SaaS is also in trouble pretty much now. Enterprise is a different thing though, the barriers to entry are not just building and maintaining the software.

I don't buy this. Real small business have enough problems that trying to vibe code a Xero replacement isn't really high on the todo list.

Small businesses also use a spreadsheet e-mailed from person to person. A vibe-coded x_table or x_base powered app would get them 80% there with minimal cost. I'd put it in a "it depends" category of things that might or might not happen in the near future.
