Nothing yet, agents analyze code which is textual.
The way they analyze binaries now is by using textual interfaces of command tools, and the tools used are mostly the ones supported by Foundation Models at training time, mostly you can't teach it new tools at inference, they must be supported at training. So most providers are focused on the same tools and benchmarking against them, and binary analysis is not in the zeitgeist right now, it's about production more than understanding.
The entire MCP ecosystem disagrees with your assertion that “you can’t teach it new tools at inference.” Sorry you’re just wrong.
