   Async – Claude code and Linear and GitHub PRs in one opinionated tool▲107

   Hi, I’m Mikkel and I’m building Async, an open-sourced developer tool that combines AI coding with task management and code review. What Async does: - Automatically researches coding tasks, asks clarifying questions, then executes code changes in the cloud - Breaks work into reviewable subtasks with stack diffs for easier code review - Handles the full workflow from issue to merged PR without leaving the app Demo here: https://youtu.be/98k42b8GF4s?si=Azf3FIWAbpsXxk3_ I’ve been working as a developer for over a decade now. I’ve tried all sorts of AI tools out there including…

    Go Micro – A distributed systems development framework▲115

    I can't tell if HN is the right kind of place for this stuff anymore since people are so advanced in their use but I thought it was interesting to leverage my existing Go microservices framework and turn it into the core of what would provide tools for an agent cli or whatever beyond that. Extensibility is key. Thought I'd share and get a conversation going.

    An MCP server that turns async-work practices into tools▲22

    More than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI. What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation? What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI): > claude mcp add open-async -- npx -y…
