I've been messing with GPT APIs for years but man I just started building this custom autonomous agent for a small law firm in London and I'm totally geeking out. Need to have a prototype ready in two weeks but I'm hitting a wall. I thought I had the hang of it with basic RAG but agents are a totally different beast. My current build keeps getting stuck in these infinite reasoning loops even with a solid system prompt.
It made me realize I'm probably missing some core architecture logic here. Besides basic tool use and long-term memory, what are the top essential skills an agent actually needs to stay on track without me babysitting the run? Is it more about self-reflection or is there a better way to handle planning...
^ This. Also, Ive had amazing success focusing on deterministic guardrails! My legal bot journey taught me that safety is everything. I compared two methods:
Honestly, agents are way overrated right now. I had issues with loops because everyone trusts the reasoning too much. Unfortunately, even OpenAI GPT-4o API breaks if you dont force strict outputs. I tried LangChain Framework Python but it was not as good as expected for logic. Self-reflection is just another chance for it to fail tbh... Use deterministic state machines or you will be babysitting it forever.
> Is it more about self-reflection or is there a better way to handle planning... Jumping in here because I love the energy! Honestly, its all about hierarchical planning. Instead of letting one agent spin its wheels, use a manager-worker setup. I found that CrewAI Framework is amazing for this because it lets you bake in a process that forces a handoff. Tbh, self-reflection is okay but it gets expensive fast and sometimes just loops the same mistake over and over. For the actual brain, Anthropic Claude 3.5 Sonnet API has been fantastic for my legal workflows lately... its super sharp on logic and handles long contexts without getting as lost as others. If you're worried about costs, try routing the simpler validation tasks to Groq Llama 3 70B since its insanely fast and cheap. Definitely helps keep the agent from looping forever because a manager agent can just kill the task if it sees the same output twice!
