Six months ago I replaced half my workflow with AI agents. Scheduling, research, drafting emails, summarizing meetings. It worked great for about a week.
Then I noticed something nobody talks about in the hype articles.
Every single morning, I had to re-explain everything.
"Here's the context. Here's what we decided last Tuesday. Here's why we're not doing it the other way." Same briefing, different day. The agent was smart. It just had no idea who I was.
The actual problem isn't intelligence. It's continuity.
I tested five different setups trying to solve this:
1. Pasting context manually — Works, but defeats the purpose. I'm spending 10 minutes every session just getting the agent up to speed. That's not automation, that's babysitting.
2. Long system prompts — Better. I built a 2,000-word "about me and my work" prompt. Helped a lot. But it still doesn't capture what happened yesterday.
3. External memory tools (Mem.ai, Notion as context) — This is where it gets interesting. I now maintain a "state file" — a plain text document I update at the end of each day. Key decisions, open questions, what I'm working on. The agent reads it at the start of every session.
It's manual. It's a bit annoying. But it works.
4. Vector databases — Tried this for a week. Too much setup for a solo operator. Maybe if you have an engineering team.
5. Persistent agent setups — The most promising. Some tools are starting to solve this natively. The agent actually remembers previous conversations. Still early, but this is the direction.
What I actually do now
Every Friday, I spend 15 minutes updating my "agent context file." What shipped, what changed, what I'm thinking about next week. Monday morning, the agent reads it and we're immediately productive.
It's not perfect. But it's the closest thing to a working memory system I've found.
The agents are getting smarter every month. The memory problem is getting solved slower than people think. Until it's fully solved, the humans who build good context systems will have a real edge.
What's your approach to agent memory? Curious what's working for others.
