## Description

The sandbox-sdk is a development kit designed for building secure, isolated execution environments on a global edge network. It provides a framework for creating ephemeral, containerized workspaces that allow developers to run untrusted code, manage build tasks, and host automated scripts without compromising host system security. By leveraging a serverless runtime, the platform enables the deployment of these environments directly at the network edge to ensure low-latency performance.

The platform distinguishes itself by integrating language models with sandboxed execution, facilitating the development of autonomous AI agents that can perform dynamic tasks and generate code. It includes specialized features for interactive remote development, such as persistent terminal sessions and real-time stream multiplexing, which allow for active debugging and observation of processes. Security is managed through automated credential injection and network access controls, ensuring that sensitive authentication tokens remain hidden from the code running within the sandbox.

Beyond its core execution capabilities, the platform supports a broad range of workflows including web application hosting, automated build pipelines, and remote filesystem management. It provides tools for mapping internal container services to public-facing subdomains, enabling secure remote access to hosted services. The system also includes observability features to capture runtime diagnostics and caching mechanisms to accelerate development cycles by reusing build artifacts.
