Under the hood
Handoff between multiple Claude Code instances sharing an inbox no longer checks a separate on/off flag
What
When several Claude Code instances share a messaging inbox (for example over tmux) and negotiate which one takes over replying, the negotiation logic no longer checks a separate feature flag before proceeding. It now only checks whether messaging itself is available.
Why
This simplifies the takeover negotiation to depend on one condition instead of two, so the behavior now hinges only on whether messaging is working rather than an additional switch.
