Isolated Sandbox Execution

E2B gives an AI application a short lived, isolated environment to run code without touching the host machine or a customer's production systems. A Beam agent opens a sandbox when a workflow calls for code to be written and executed, such as checking a calculation or parsing a file, reads the output the sandbox returns, and applies the customer's rule for what happens next, for example writing a passing result into another system. Code that errors, times out, or tries to reach outside the sandbox is stopped and the case is routed to a person to inspect.

File and Data Handling

A sandbox can be given files or data to work on, so code can read a spreadsheet, reshape it, and hand back a result without that data ever leaving the sandbox. A Beam agent uploads the files a task needs, lets the AI generated code run against them under the customer's approved settings, and reads back the produced output or file for the next step in the workflow. Where the output does not match the expected shape or a file fails to process, the task is set aside for a person to check before it is used anywhere else.

Session Reuse

A sandbox can be kept running across several steps instead of starting fresh each time, which matters when a task builds up state, like installing a package and then using it. A Beam agent reuses the same sandbox session for a multi step job, applying the customer's rule for how long a session may stay open, and closes it once the job reports done. Sessions that run long, or repeatedly fail and restart, are not left open quietly, they are flagged to a person so the sandbox can be checked or shut down by hand.
