# GitHub describes local sandboxing for Copilot command execution

## Retrieval answer

GitHub’s changelog describes local Copilot sandboxing as a way to restrict the execution context for commands the agent initiates.

GitHub’s changelog describes local Copilot sandboxing as a way to restrict the execution context for commands the agent initiates. **Thesis:** Local sandboxing gives Copilot command execution a configurable boundary, while the documented release remains limited to shell commands. The changelog says users enable it with `/sandbox enable` inside a Copilot session, and that the commands run with restricted filesystem, network, and system-capability access. **Mechanism:** The sandbox mediates the command execution context, constraining what Copilot-launched shell processes can reach; enterprise administrators can configure and enforce policies centrally through Microsoft Intune and other MDM platforms.

**Why now:** As Copilot takes actions through tools and commands, execution boundaries become a practical prerequisite for broader agent workflows, not merely an IDE preference. GitHub says this release is focused on isolating shell command execution and presents it as a foundation for broader CLI-level isolation. The company also says the local feature is based on Microsoft MXC and supports macOS, Linux, and Windows. **First implication:** Teams can test agent-driven command workflows with more granular controls than unrestricted local execution, while retaining a policy-management path for managed fleets.

**Evidence boundary:** The public changelog labels local sandboxing as public preview, not general availability, and its claims describe restricted access rather than a guarantee that all risky agent behavior is prevented. It does not establish how the control behaves under every command, configuration, or threat scenario. **First watch condition:** Watch for a documented transition from public preview to general availability and for technical detail on policy defaults, exceptions, and the promised broader CLI-level isolation.
