GitHub brings sandbox and account boundaries into Copilot's daily workflow
GitHub's October 9 weekly release brings several changes that make the operational boundary around coding agents easier to manage. Local sandboxing, already introduced during the week's individual releases, is now generally available in Copilot CLI, the Copilot desktop app and supported VS Code Agent Host sessions. Its stated purpose is to restrict the files, networks and credentials available to an agent. The Copilot app can also use one GitHub account for the Copilot license and a different account for repository access, separating subscription identity from code authorization. In Copilot CLI, the /model command can discover supported models from an already-running local Ollama installation alongside other configured choices. VS Code's Agents window adds side-by-side sessions; a worktree-cleanup command helps identify and remove inactive session worktrees. This is a weekly digest, not a claim that every feature first launched on October 9. Capability and deployment details should be checked against the linked product documentation before an enterprise-wide rollout.

Why it matters: Coding-agent productivity increasingly depends on the harness around the model: enforce least-privilege file and network access, distinguish billing identity from repository authorization, keep parallel agent work isolated and remove abandoned working copies deliberately. A practical adoption test is to run a non-sensitive issue under a restricted sandbox, verify which tool calls are denied, and compare the final code and audit trail with an unrestricted development workflow.
