Summary
The e2b group moves the agent's file and command work into a remote Linux sandbox: file reads and writes, shell commands, and terminals all run in one remote world instead of on your machine. Three packages work together — one provides the shared sandbox, one runs file operations in it, and one runs commands and terminals in it. Existing shell, terminal, and language-server features keep working unchanged once the family is enabled, so no E2B-specific tooling is needed. The harness process, model calls, and session state never move — only the execution world is remote, and the sandbox is ephemeral. It is an experimental POC, and no shipped composition enables it by default.
