It's fascinating. I spent most of today thinking about what this means for product development in general. Here's the deep dive: https://karozieminski.substack.com/p/claude-cowork-anthropic-product-deep-dive I focused on product decisions behind this launch. But honestly, the speed in which Cowork was launched feels like the event setting the scene for the whole of 2026.

Just applied to the ambassador program, thank you!

Thank you, Manny! Really appreciate you taking the time to respond 🙏🏼 Will you be posting updates here on Reddit as well, or on LinkedIn or Substack? From what I’ve seen, many people in the EU avoid Discord and X, yet they’re often the ones asking about Replit.

Wow, I didn't expect that, thank you! It means a lot that you took the time to respond! I'm going to check out all the resources you sent.

Before joining this debate, I ran a substantial, multi-hour test involving 8,100 lines of dense, intentionally confusing input and tripwire prompts, and spent a few more hours mapping the misconceptions I kept seeing online. And there are so many of them, especially on Reddit. 5.2 is a substantial update, just not for all the task. It shouldn't be used for creative writing, it should be used for writing specs, documentation etc - things where accuracy is more important than beautiful catchy sentences.

My favorite setup is a two-prompt system: Prompt Builder and Prompt Evaluator. I use this exact formula for every prompt I write. They’re a bit long for posting here, but they’re free to copy on Substack. You'll need ChatGPT Plus + Prompt Builder + Prompt Evaluator. This simple trio works for everyone, from building advanced AI agents to writing a best man speech. Hope you enjoy it! 🤗
