Agent OS v2 is here: It's my free, open-source system that trains your AI coding agents to build like YOU—with ANY AI tool (Claude Code, Cursor, Codex, Gemini, or any other).
Stop re-explaining your coding standards. Stop fixing the same mistakes. Stop the endless prompt loops. Agent OS v2 gives you a proven system for spec-driven development.
What's new in v2:
→ Modular architecture that adapts to YOUR workflow
→ Multi-agent orchestration for complex builds
→ Tool-agnostic design—no vendor lock-in
→ Enhanced alignment to your coding standards
Whether you're a solo developer or leading a team, Agent OS gives you the consistency and control you need to actually ship with AI.
Training and community for developers and founders building with AI.
Created by Brian Casel (that's me) — multi-time founder, product designer, teacher, and the creator behind Builder Methods.
