Claude Code's new messaging feature lacks file protection, users advised to use worktrees

By PulseAugur Editorial · [2 sources] ·

Anthropic's Claude Code now supports cross-session messaging, allowing two instances to communicate and share information. However, this feature does not prevent simultaneous file overwrites, as messages only convey text and conclusions, not file locks. To safeguard against data loss, users are advised to utilize separate worktrees for each Claude Code session, ensuring each session has its own isolated directory and copy of tracked files. For files that both sessions need to modify, a protocol of assigning ownership and requiring handoffs before touching shared files is recommended. AI

IMPACT This feature highlights the ongoing development of AI agent coordination, but its current limitations necessitate careful manual oversight for file management.
