What
In agent teams, Claude Code can run teammates, which are extra Claude agents working alongside the main one. A setting chooses where they run: inside the main Claude Code process, or in separate tmux or iTerm2 panes, which are split sections of a terminal window.
When the permissions.blockFileToolReadsOutsideWorkingDirectories policy is active, Claude Code now always runs teammates in-process and skips tmux and iTerm2 panes. Before, it went straight to your teammate-mode setting.
Why
If this policy is on, a tmux or iTerm2 teammate mode you chose is overridden, and teammates no longer open in their own panes.
