[Other] Show HN: DiffCAD, a FreeCAD workbench to review model changes like code I&#x27;d like to share a new workbench I&#x27;ve been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses&#x27;, too!<p>I&#x27;m open to feedback, ideas, and contributions. Cheers!

[Testing] Show HN: Resurf – realistic, reproducible test framework for AI browser agents Systematic testing of browser agents today is not easy: testing on real websites is flaky, rate-limited and potentially expensive (e.g. using proxies or bypassing Captcha), while static-HTML benchmarks lack state and dynamic behavior.<p>Resurf gives your browser agent a realistic, stateful, instrumented framework — built on synthetic websites with failure-mode injection:<p>- Realistic, dynamic, interactive environment - Deterministic &amp; reproducible - Failure-mode injection (latency, payment errors, 5xx) - Auditable success eval (DB state, not LLM judge) - No dependency on live websites - Browser Use and Stagehand supported out of the box

[CLI Tool] Show HN: Stage CLI – an easier way of reading your AI generated changes locally Hey HN! We&#x27;re Charles and Dean. A few weeks ago we posted about Stage, a code review tool that guides you through reading a PR step by step - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=47796818">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=47796818</a>.<p>We got a lot of great feedback but also heard from many people that they wanted to have the chapters experience even before opening a PR… so we built the Stage CLI as the local, open-source version that anyone can try.<p>Here’s a quick demo video: <a href="https:&#x2F;&#x2F;www.tella.tv&#x2F;video&#x2F;stage-cli-demo-f55q" rel="nofollow">https:&#x2F;&#x2F;www.tella.tv&#x2F;video&#x2F;stage-cli-demo-f55q</a><p>It works with any coding agent of your choice. The skill instructs the agent to read your current branch’s changes, break them down into separate logical chapters, and open them in a local browser.<p>We’ve found that reading changes this way is a lot easier for us than reading them in an IDE or other similar CLI tools, which present diffs to you in repository tree order. You can see a few examples of what it feels like here: <a href="https:&#x2F;&#x2F;stagereview.app&#x2F;explore">https:&#x2F;&#x2F;stagereview.app&#x2F;explore</a>.<p>Try it out and let us know what you think! Would love to hear any feedback :)

[DevOps] Show HN: Kstack – Skill pack for monitoring/troubleshooting K8s in Claude Code Hi All,<p>Recently I&#x27;ve been using Claude Code a lot for debugging cluster issues and I realized I was performing similar tasks repeatedly so I decided to package them up into skills so I could call them up more easily (e.g. `&#x2F;investigate`, `&#x2F;audit-security`, `&#x2F;audit-outdated`). I&#x27;m calling the skill pack &quot;kstack&quot; and the goal is to be able to monitor and troubleshoot K8s from within Claude Code.<p>If you have time, I&#x27;d love to get some feedback on the project!<p>Andres<p>Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;kubetail-org&#x2F;kstack" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;kubetail-org&#x2F;kstack</a><p>Docs: <a href="https:&#x2F;&#x2F;kstack.sh&#x2F;" rel="nofollow">https:&#x2F;&#x2F;kstack.sh&#x2F;</a>
