Prevent Claude Code Agent Teams from using tmux inside Claudio#664
Conversation
Write teammateMode: "in-process" to .claude/settings.local.json in each worktree before Claude Code starts. This prevents Claude Code from detecting $TMUX and activating tmux-based Agent Teams, which creates nested sessions Claudio cannot manage.

The settings.local.json approach from #664 can be overridden by user-level settings or $TMUX auto-detection. Pass the flag directly on the CLI for both start and resume commands to guarantee in-process teammate mode at the highest configuration precedence.
