> Models know git because there's a monstrous amount of git in their training data. Models never heard of a new thing "for agents", so you have to teach them to use it via skills and docs.

Another option: when model invokes standard tool, rewrite the invocation to newfangled tool.

Bunch of ways of doing it:

(a) Invocation of standard tool returns error saying to use newfangled tool instead

(b) Invocation of standard tool returns message saying it has been dynamically rewritten to invoke newfangled tool, followed by newfangled tool output

(c) Invocation of standard tool in context is dynamically rewritten to invocation of newfangled tool, prior to execution

In case (c), the model ends up thinking it somehow knew about this new thing all along, even though it actually didn’t
