I don't do much with most of the sessions.

In my experience 95% of the session transcript I don't care about.

But there are some that I want to keep and maybe come back one month later.

Usually it's not even engineering-related. Maybe doing some research on visas, relocation.

But sometime also doing project research and sometime I want to come back to the same topic 2 month later(because new things came up) and I want my new agent to go and read prior conversation.

Yeah understandable, with skillsync you can choose for it to proactively tell you about past work that's related to what you're doing or just access all your past sessions via mcp. It's like being a musician that has the record button on the whole time for when the crazy idea strikes
