bx - macOS sandboxing for AI

bx is a macOS security tool for sandboxing AI-related applications and development tools. The description says it can wrap VSCode, Claude Code, Xcode, or any app in a macOS sandbox so the tool only has access to the specific project being worked on. This positions it as a way to limit file visibility and constrain application access on a per-project basis. Based on the provided input, bx is focused on local isolation and access control for AI-assisted workflows on macOS, helping users reduce unintended exposure of files outside the active project environment.
