What it does

I built lean-dev, an open-source AI skill for coding assistants like Claude Code, Cursor, ChatGPT, and GitHub Copilot. lean-dev attempts to address : 1. Think Before Coding 2. Simplicity First 3. Surgical Changes 4. Goal-Driven Execution 5. Lean Responses One interesting result during testing was a significant reduction in token usage (often around 75%) while still producing useful outputs.

⚡ Talk less. Code better. — A Claude skill combining caveman communication + Karpathy coding principles. Works with Cursor, Windsurf, ChatGPT & GitHub Copilot too. - Vishnu90Coreinn/lean-dev

lean-dev is an open-source Claude skill that teaches coding assistants to behave more like experienced engineers. "The models make wrong assumptions on your behalf and just run along with them without checking. They really like to overcomplicate code and APIs, bloat abstractions, implement a bloated construction over 1000 lines when 100 would do." Refactor my auth module to be more scalable. Typical AI Response Generates new abstractions Suggests strategy patterns Creates interfaces Reorganizes folder structure Produces hundreds of lines of code lean-dev Response Need more information first. 1. What's painful about the current auth module? 2. What's the current stack? 3. What future…from github.com

    Hi 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…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  • Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
