Purely Declarative Infrastructure
All Keystone software is built on a purely declarative foundation. Unlike traditional procedural code that describes how to achieve a state, declarative configuration describes what the state should be.
- Version Control Integration: The entire system state can be committed to Version Control (VCS), ensuring a perfect audit trail and reproducibility.
- AI Agent Empowerment: This architecture empowers AI agents to freely propose architectural changes, debug complex issues, or implement new features autonomously.
- Automated Verification: Agent-driven changes can be rigorously reviewed and verified in CI (Continuous Integration) environments before deployment, ensuring system stability and trust.
