Kernel CLI has native computer-use commands (i.e. no Playwright). It’s intuitive enough that OpenCode + Opus 4.5 can just drive a browser and read the HN front page. (cc Rhys)

Did you know that Claude Code can use the browser to QA its own work? 1. Run `claude mcp add playwright -- npx -y @playwright/mcp@latest` 2. Tell Claude where your app is running, e.g localhost:8000 3. Now Claude can click and type to make sure its code is actually working!

BREAKING NEWS: Anthropic just dropped Claude Ops 4.5!! It is by FAR the best coding model I've ever used. We've been testing it internally Every 📧 for the last few days, and it is an absolute paradigm shift for any kind of coding task. It extends the horizon of what you can vibe code The current generation of new models—Anthropic’s Sonnet 4.5, Google’s Gemini 3, or OpenAI’s Codex Max 5.1—can all competently build a minimum viable product in one shot, or fix a highly technical bug autonomously. But eventually, if you kept pushing them to vibe code more, they’d start to trip over their own feet: The code would be convoluted and contradictory, and you’d get stuck in endless bugs. We have not found that limit yet with Opus 4.5—it seems to be able to vibe code forever. Takes working in parallel to a whole new level because it's far better at planning and coding, it can work with more autonomy—meaning you can do more in parallel without breaking anything . Kieran Klaassen worked on 11 different projects in six hours—and had good results on all of them. Great at design iteration Opus 4.5 is incredibly skilled at iterating through a design autonomously using an MCP like Playwright. previous models would lose the thread after a few cycles, or say a design was done when it wasn't. Opus 4.5 is incredible at autonomously iterating until a design is pixel perfect. we have a full 4,000 word vibe check on Every 📧 right now with everything we tested:

OpenAI Symphony is actually great You can 5x Coding agent outcome with it + Good codebase harness Played with it past few days and here is my setup: - Playwright CLI - Boot skill - WORKFLOW.md ... Broken it down in 12 mins below so you can do the same 👇

Claude Opus 4.5 is an insane model and if you're not getting good results you have a skill issue. It's mind-blowing. You can just make anything you want if you care enough and write your prompts prope-

This is how I’m currently running my startup with Devin + OpenClaw🦞 The browser testing in Devin is mind-blowing. I was trying to duct tape and jerry-rig all this stuff together with Playwright + uploading videos to PRs and all sorts of stuff and Devin just does it all e2e. Wild. I didn't show how I'm using Linear, which I am using for issue tracking. I have a "land" skill that I tell Devin to use whenever all the browser testing is done and all the CI goes green and it just merges the PR

So I've been using Tourbox for a while, and it has really improve my workflow a whole lot! And i can focus on what I'm working on screen while pressing shortcuts without have to lifting my hand. You can also check out TourBox quiz page here

Here is the recording ( page load ) NextJs on left ( 1.38 s = 1380ms ) Tanstack Start on the right ( 209ms ... ) ~7x - Playwright is now less flaky, 100% faster - Rendering and navigation is at least 3x faster across all dynamic and non-dynamic pages - file structure is more sane and customizable - just works client side and server side...... - Fast, easy to understand...

Been testing 5.4 for about a week now and it's really good. It's the first model that kinda "just works". A hybrid of 5.3's precision and opus' speed/initiative I've done ~300 million tokens with it and it's crushed almost everything I've given it. Except for UI. It's hilariously bad at UI stuff.

The person who built Claude Code just explained how he is using it "Now I just have an army of agents that are doing stuff" Only 18 minutes, the best Claude guide on the internet right now. Boris Cherny covered: > how Claude Code is moving beyond just engineers > routines for CI, code review, and daily workflows > why the loop is the next big leap > working with hundreds of agents at once everything is already running through agents, ignoring this is not an option that's exactly why I wrote a full guide on how to build one yourself with Claude Code article below
