How do teams collaborate with ai coding agents in real time?

Still figuring this out, we are four devs and each one of us drop a Slack msg saying what got changed at the end of the work session. The next person reads it and briefs their agent from scratch. It kinda lagging. We tried diff things: * One agent per person and we treated them like separate contributors. Fell apart when two agents made conflicting decisions about the same module at the same time. * We shared CLAUDE.md with everyone as updates but lasted about 3-4 days before it started drifting. Context files only stay accurate if everyone treat this as the most imp priority. * We even tried designating agent time slots so only one person runs an agent at a time. Collision doesn't happen but velocity decreases. The conflicting decisions problem we hit is exactly what a shared runtime is supposed to prevent. What setups teams of more than two are actually running? Pls help
