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 & community for pro software developers building with AI.
Created by Brian Casel (that's me). I'm a career software developer, founder, and creator of Builder Methods and Agent OS, the system for spec-driven development with AI.
