Agent OS v3 is here — rebuilt from the ground up for how we actually build in 2026. I stripped out 70% of the framework. What's left: a leaner system for discovering, documenting, and injecting your coding standards into AI-powered, spec-driven development. In this video, I'll show you: - The new 'discover-standards' command for surfacing your opinionated patterns and documenting standards. - The new smart injection system for using your standards... anywhere, anytime. - The new way to write better, more aligned specs—without changing how you build with Claude Code or Cursor. - Using profiles for managing different standards across project types 👇 **Your Builder Briefing (free)** https://buildermethods.com - Your free, 5-minute read to keep up with the latest tools & workflows for building with AI. 👇 **Use Agent OS** (free open source): https://buildermethods.com/agent-os 👇 **Use Design OS** (free open source): https://buildermethods.com/design-os 👇 **Join Builder Methods Pro** https://buildermethods.com/pro - The membership for professionals (and soon-to-be-pros) for building with AI.
