What
A sandbox is a restricted space that limits what commands Claude runs can reach. Claude Code passes Claude instructions about the sandbox, and a note when a remote session changes. Before, these were added only when the Bash tool, which runs shell commands, was available. They are now also added when a separate check passes.
Why
This may mean Claude gets sandbox guidance in more situations.
