I actually was just thinking about doing something very similar for this but for "agent," specifically in the Microsoft ecosystem. There are a zillion different proper nouns (products, services, frameworks, toolkits and tools, SDKs etc.) containing "agent" now, plus a bunch of other things that are now "agentic".

A ton of companies use agent/agentic to mean AI that does something with external effects, as opposed to a chatbot. I’m not sure if it’s overused per se or companies are just really pushing their AI features in general.
