Best Practices for Building Agentic AI Systems: What Actually Works in Production - UserJot

Should subagents really have zero memory?
Yes. When you add memory, you add state, and when you add state, you add bugs, so keep them stateless.

How do you handle rate limits with parallel agents?
Implement a token bucket rate limiter to launch agents up to your limit, queue the rest, and process queued tasks as tokens become available.

How do you test agent systems?
Test subagents with fixed inputs and expected outputs, orchestration with mocked subagent responses, and the full system with real but limited data.
