Hi, I'm the maker. I work alone and keep many Claude Code sessions open at once, and they kept breaking each other's work without any error message. bulkhead is the set of checks I wrote for that: before an agent's shell command runs, it looks at what the other live sessions own and, if the command would hurt one, cancels it and tells the agent the safe alternative.
Before launching I wanted proof the problem was real, so 0.2.0 includes a replay of your own transcripts. Over my last two weeks it counted 507 commands that would have been blocked, with as many as 13 sessions open on the same day.
It reads command text, so it is not a sandbox, and the replay can't check ports or memory after the fact. It is free, MIT, Node 18+, no dependencies.
