Same worry got me to build pond for myself: it imports all of my sessions on a cron schedule every 5 mins into one store, and my agents can access it over MCP. Whenever I need a session from a while ago now, I just know it's in pond, because all of my sessions for about the last 1.5 years are collected in there. It also happens really often that when my agents cannot find something, they just call pond search themselves. Faster that way.
