Agent Sandbox

This is a wrapper around E2B's sandbox infrastructure that lets Claude spin up isolated execution environments on demand. You get templates for Node, Python, React, Next.js, and bare Linux boxes, plus commands to execute code, manage files, and monitor resources. Honestly most useful when you need Claude to actually run code instead of just writing it, like testing scripts, debugging environment issues, or prototyping API integrations without polluting your local setup. The lifecycle management is straightforward: create, execute, cleanup. Main gotcha is you need to handle timeouts and resource limits yourself, but that's expected when you're orchestrating ephemeral containers. Good for development workflows where you want Claude doing more than code generation.
