Three of our agents worked the same account in the same week. None of them knew about the others.

There's a couple of us working on the sales and CS side of our business. By spring this year three of us had built our own agent. Each with different jobs, depending on what we were working on. I was running one that read call notes and email and kept a running summary per account. The CSM's flagged accounts coming up for renewal. One of the AEs had one updating Hubspot after calls. They all worked. Everything was going fine. Then an account went quiet before renewal. My agent figured out why and then a few days later the CSM's agent rebuilt the same picture from the same emails and in between all of this the AE's logged a next step in Hubspot that conflicted with what my agent caught. Every agent had memory, but only of its own run and was blind to what the others were doing. The fix was stopping the each agent from keeping its own notes. Account history is all live in one place now, DevRev's Computer which we synced with Hubspot, Gmail and Slack. The agents connect to it via MCP and read the same history first. How did you guys solve the multiple agents by different people running over the same data issue?
