Prompt engineering is hot again.
Not that it ever went away, but there was a hot minute there where every AI expert was saying that prompting was dead and no one would ever need to learn prompting.
Well, that was before agents. And I don’t just mean the big, heavy, super technical ones.
ChatGPT Agent Builder. Google Workspace Studio & Opal. Claude Skills. And of course the legacy agent-like services like Claude Projects, Gemini Gems, and GPTs.
Good prompts lead to good results. Bad prompts lead to bad results. But when you put a prompt inside anything agentic – especially something meant to be autonomous, like Google Workspace Studio agents – then that prompt becomes the engine of the agent.
Got a mistake in it? The agent will make that mistake every time it runs. Got an inaccuracy, instructions that are prone to hallucination? Every time that agent runs, it runs the same prompt.
Think of it like the steering on your car. Drive down the street with a front end slightly out of alignment, and you won’t really notice. Drive 100 miles and you sure will, especially if you’re someplace without roads or a way to know you’re off course.
The very nature of autonomous AI means that small mistakes are magnified thanks to repetition.
So if you haven’t got great prompting locked in now, when you do start deploying agents (and other services that rely on prompts), you’re gonna have a bad time.
As 2026 rolls in, agentification of EVERYTHING digital is on the horizon. If it’s an app today, it’s an app with an agent tomorrow. And one of the dividing factors that will separate good from great is great prompting.
