# Sandboxed test runner for generated code

Run untrusted AI code snippets safely inside isolated environments and report test results

- When you askReceive code execution request
- ThenExecute tests in isolated sandbox
- ResultReport execution logs and status

When building automated coding workflows, generated scripts require execution and validation before merging. This bot spins up disposable sandboxes, runs test suites against proposed patches, captures runtime logs, and checks for failures without exposing host infrastructure to untrusted code.

## Prompt to start with

BotBentoRecommended

```
When a code snippet or branch is submitted for verification, launch an isolated virtual sandbox via terminal commands. Execute the provided test commands and collect exit codes, stdout, and stderr. Summarize pass or fail status and share the logs in chat. Always ask for user confirmation before deleting environment snapshots or pushing changes upstream.
