Developed a Daytona-based workspace package for the mastra-ai/mastra repository, implementing the WorkspaceSandbox interface using the Daytona SDK to achieve workflow parity with the existing e2b solution. The work focused on enabling cloud sandboxes and full lifecycle management within the workspace, supporting robust command execution with features like environment variable merging, quoting, and timeout handling. Comprehensive test coverage was established through 59 unit tests and an integration suite, ensuring reliability. The project utilized TypeScript and Node.js, with updated CI workflows and documentation to support cloud testing and developer onboarding, ultimately reducing external dependencies and improving environment consistency across deployments.
