If it doesn’t work as a prompt, it won’t work as an agent.
I toyed with OpenAI’s new Agent Builder, which is like a watered-down N8N or Zapier. It’s obviously locked to the OpenAI ecosystem, so you can only use their models or infrastructure.
First, to be clear, this launched on DevDay. A lot of folks frothing on social media about this are not developers, and are loudly complaining about how unintuitive it is. Yeah. It’s for developers. Things like MCP calls, local vector stores, etc. are all intended for use by developers building agents.
That said, like Google Opal, it’s a slick, simple workflow builder for building agents that requires no extra infrastructure on your part.
Now, the important part: at its core, it’s a wrapper around an LLM. That means that if you want your agent to function well, it has to have a bulletproof prompt. I say this in my workshops and keynotes: if it doesn’t work as a prompt, it won’t work as an agent.
Before you type one character into the agent interface, make sure you have tested the hell out of your prompt in the regular system. Put it through a prompt optimizer. Test it and make sure it reliably works, because if it doesn’t work in a chat, it will not work in an agent. It’ll just not work at scale and cost you a lot of compute time/cost while not working.
For example, I built a super simple agent as a test to do media monitoring. Before I pasted even one line into the agent, I made sure it worked in regular ChatGPT. (spoiler: it took about 5 iterations to get it right)
Think of prompting like software development, like the dev version. Think of the agent like the production version. Don’t rush a dev alpha into production unless you want a really bad time.
A good prompt becomes a better agent.
A bad prompt becomes a worse agent.
