Agent OS v3: Leaner & Smarter for How We Build in 2026

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:

  • How discover-standards surfaces the tribal knowledge hidden in your legacy codebase
  • Smart injection that loads only relevant standards into context
  • Profiles for managing different standards across project types
  • Enhanced spec shaping that works with plan mode to create better specs
