.well-known/
Stop polluting the root dir.
I'm not a fan of the name "well-known", but at least it's a convention [1].
I think it'd be great if we took something like XDG [2] and made it common for repositories, build scripts, package managers, tooling configs, etc.
I guess I was one of the lucky 10000 :-)
I think all this agentic stuff could live quite happily in $REPO/.config/agents/.
