What it does
A Claude Code skill that reviews code changes for unintended behavioral regressions. npx skills add https://github.com/imaman/skills --skill regression-dog Usage Start a fresh Claude Code session and ask it to review your changes: flag all regressions in this branch The skill also triggers from natural-language prompts about reviewing changes or checking for breakage, so the slash command is not the only way in. The output is split into two sections. Regressions come first, numbered and tagged with severity. Each one describes a behavioral delta: "this used to do X, now it does Y." After that, a Cleared section lists everything that was reviewed and found safe, so you can see the skill…from github.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
