I would classify AnyTool as a context engineering trick. It's using GPT-4 function calls (what we would call tool calls today) to find the best tools for the current job based on a 3-level hierarchy search.
Drew calls that one "Tool Loadout" https://www.dbreunig.com/2025/06/26/how-to-fix-your-context....
So great. We have not one, but two different ways of saying "use text search to find tools".
This field, I swear...it's the PPAP [1] of engineering.
