What is Agent OS?
Agent OS is a spec-driven development system that gives AI agents the structured context they need to write production-quality code. It provides your AI with clear specifications, standards, and workflows—transforming inconsistent outputs into reliable, production-ready implementations.
How it works
Agent OS uses a 3-layer context system:
- Standards - How you build (your coding standards that train your AI agents)
- Product - What you're building and why (vision and roadmap and use-cases)
- Specs - What you're building next (specific features with implementation details)

Choose your mode
Agent OS works in two modes to support any AI coding tool.
- Single-agent mode - Works with Any AI coding tool (Cursor, Codex, Gemini, Windsurf etc.). Use single-agent mode when your tool does not support subagents. In this mode, you serve as the orchestrator, feeding Agent OS-generated prompts to your AI coding agent.
- Multi-agent mode - Currently only available for Claude Code. Specialized subagents work autonomously in parallel for more efficient, hands-off development.
