Run several sessions on one repo. Sessions see each other's work. A task that clashes with another session's running work is queued and starts from that session's merge, and both supervisors are told. Supervisors get an "other sessions in this repo" summary and a who_is_working tool.
Pick a session when you start. Bare brindle lists the repo's open sessions in any worktree and preselects the one in your checkout; brindle -c lists paused sessions, newest first.
Shared decisions. Record a decision once (record_decision) and every session's workers get it in their brief when they touch the files it covers. A conflicting decision has to replace the old one explicitly. brindle decisions lists them; brindle decisions export writes them out.
A knowledge base of your docs.brindle kb add folder <path> indexes a folder on your machine; agents search it with kb_search, and the best matches reach worker briefs as clearly marked reference material. Secrets are redacted and hidden instructions quarantined when docs are added. kb list, kb sync and kb remove manage sources.
Coordinator (Pro). Turn on "coordinator": true and a coordinator wakes when sessions clash or decisions change. It can hold, release or reorder queued work and propose decisions, never touches running work, and every action can be undone (brindle coordinator undo). brindle coordinator log shows what it did.
Fixes
brindle no longer moves your terminal. Running brindle from a background pane could switch your own tmux client to another session.
Quiet while it waits on you. Autopilot stops repeating "the goal isn't reached" while a question to you is open.
Plan and org changes arrive within minutes. New plan features and a removed org Claude route reach your machine without signing in again.
No more "locked" agents after signing in. Agents started while signed out of brindle are adopted by the account that signs in.
