I appreciate you keeping up the fight for correct terminology! I think at this point though there is a "standard" definition of agent - an AI that can actually utilize external real-world tools to do things on behalf of users. That fits coding agents, web-using agents, etc.

Do you think there's still confusion around it like there was a year ago?

Definitely. The one you are using there is pretty much the accepted software engineering definition now, but if you talk to non-engineers you'll still hear all sorts of variants about things like travel agents or UI automation or "autonomy" without explaining what that means.

Anthropic use the tools-in-a-loop one quite consistently now, but OpenAI still sometimes say things like "AI agents are AI systems that can do work for you independently. You give them a task and they go off and do it." - https://simonwillison.net/2025/Jan/23/introducing-operator/
