Just me or Codex and OpenCode *much* worse at automatically using skills than Claude based on just the prompt text? Need to explicitly invoke them for them to be used.

Another http://ui.sh before/after shot — still early and lots to do but it's getting better! Same prompt, just with and without our taste layer 👅

What model are we using this week fellas?

I don’t think AI is lowering the barrier to entry as much as it is giving the very smartest people an even more enormous advantage.

Has anyone ever put together evals for their own rules/skills specifically for Claude Code (not just Opus using the API)? Curious what approach you used if so!

Bullish on tools that build for existing agents as the platform, instead of wrapping everything up into yet another app I have to visit and use.

If you're building a new product, make sure you can name a real human being who you think would be a customer. Not a persona, a person. It sounds so extremely obvious but it's so easy to get lost in the details of a "good idea" and stop evaluating it against this basic test.

Turned my first non-programmer friend on to Claude Cowork this week.

If you use the Claude Agent SDK and don't provide an API token, it automatically just uses your installed Claude Code instance with your preconfigured authentication. Is that against the terms now? 🤔

LLMs are of course completely non-deterministic, but surprisingly deterministic at the things you don't want to be deterministic. Given 12 color palette options and a prompt to design some UI using a random palette from the list, it literally always picks the same one 🫠

Some more http://ui.sh before and after magic ✨ Just harvesting low hanging fruit all day every day over here but it adds up!

Too excited to be more strategic about sharing — demos coming this week ✨ https://ui.sh

One of you AI companies better buy us next or I'm going to make a bunch of breaking changes and invalidate all of the code you generate.

Finally setting up my Christmas present 🤖 No idea what I’m doing 💪🏻

We moved Refactoring UI over from Paddle to @stripe's new managed payments product last week and although it's a bit early to say for sure, I am pretty confident we are already making more money. Never would have believed it but the checkout does seem to convert significantly better, and I think it's entirely because of Link.

Sneak peek at some https://ui.sh stuff 🫣 This is our local development environment where we can compare what the models generate by default to what they generate with our opinions layered in. So much more to do, but already obvious improvements from just focusing on little details like hanging punctuation, card content alignment, lighting/elevation cues, and edge highlighting of avatars.

Man don't sleep on Claude Code in the desktop app/on the web. I feed this thing every little random tedious OSS task that I'd otherwise neglect on my TODO list and it just churns through it all asynchronously flawlessly while I work on more important stuff. So, so, so good for brainless work.

I cherish any time I have an excuse to mock up ideas in Excalidraw, such a lovely tool.
