Shipped my second newsletter issue.

It's rough. But it's real.

This week: Why your LLM is nondeterministic, Warp's new AI agents, and Microsoft hedging their OpenAI bet.

That moment when you realize you've been doing pwd → manually copying the path like a caveman 🦴

Just add this to your shell config:

alias pwc="pwd | pbcopy"

Now "pwc" instantly copies your working directory to clipboard. Such a simple thing but it genuinely sparks joy every time I use it.

🔥 The ability to keep chatting with Claude Code whilst it's executing tasks is a bigger deal than it sounds.

Every other LLM blocks input during execution. Claude Code just... doesn't. You remember something? Add it. Requirements change? Update them. No restart needed.

hit 10 stars on the product as code repo today ⭐

"a journey of a thousand miles begins with a single step" and all that

but genuinely excited - each star is a developer who sees the same broken workflow we do

Why this was never adopted is beyond me 😂

🛠️ Coming soon: PAC CLI v0.1.0

> pac init
> pac create epic "user-auth"
> pac validate

Version-controlled product management that your AI coding assistants can actually understand.

The future is git-native product development 🚀

Conversations with Claude Code. Always worth asking...

I always loved Conventional Commits. Time to start using new type "ai".

The most annoying "feature" of Claude in desktop app by far is the fact that it is not great at rewriting and updating documents. It messes them up a lot, to the point that I have to ask it to write it from scratch.

Just got Claude AI running in Docker container with full browser terminal access.

Implications are huge - work on a project remotely as long as you have full #ProductAsCode set up.

Can Anthropic own programming long term?

With #productascode updating docs can be as simple as that.

I managed to hit the context window limit for Claude Pro which is currently 200k+ tokens (about 500 pages of text or 100 images)...

This actually feels quite good. Managing my product in code.

I am working on a new idea, as one does. I used Gemini 2.5 to give me feedback on the idea. I then asked Claude what it thought about its quality:

"The response seems designed to make you feel good about the idea rather than help you understand what you're really up against."

😂

Now that's gonna keep me quiet! 😂
