Declarative Image Builder allows agents to build custom Docker images directly through the SDK without requiring manual downloads, setup, or registry interactions. This new feature simplifies image creation by removing complexity and providing a zero-human, zero-DevOps interface for environment creation. It enables true autonomy in agent operations, enabling them to spin up tailored environments on demand without needing to install Docker or touch a registry. The Declarative Image Builder is now live in the Daytona SDK, marking an important step toward agents being able to ship code directly.
