Adds help and gather_perspectives tools that create bounded hidden model threads for read-only expert analysis and cited synthesis; planner/worker provider, model, reasoning, and permission settings control cost and authority.
Add, choose, configure, route, or coordinate who runs a thread.
HandoffMoves a whole session between agents and machines in both directions: hands a bb thread's rendered transcript to another provider (optionally on another enrolled machine, carrying uncommitted work as a patch), or adopts a Claude Code, Codex, Gemini CLI or OpenCode session from your terminal as a bb thread in the same directory.

BotsAdds a Bots panel to the BB sidebar where you create named bots with their own instructions, provider, model, reasoning level and optional project, then chat with them; each bot's instructions are bound per-thread, so a persona applies only inside that bot's own chats.
