Claude Code 2.1.314 Adds Write Guard

Claude Code 2.1.314 adds `permissions.blockWritesOutsideWorkingDirectories`, making Write, Edit, and NotebookEdit refuse paths outside approved working directories—even in bypass-permissions mode.

// ANALYSIS

This is a meaningful safety improvement for autonomous coding workflows, but it is a targeted file-tool boundary rather than a complete filesystem sandbox.

–Protects against accidental or prompt-injected edits to files outside the project
–Applies across permission modes, including `bypassPermissions`
–Covers Write, Edit, and NotebookEdit specifically
–Developers can extend the boundary through additional working directories
–Shell-based commands may still require separate sandboxing or permission controls
