Many games do happen to be set up this way wrt their input systems if they happen to leverage Steam input. Player actions in game are defined as abstract verbs with concrete input device binding being left to the player / underlying system. Valve is trying to nudge games towards being platonic objects isolated from specific systems (so they'll be readily compatible steam deck, vr, pc etc...). Translating these verbs in an automated way with an agent is an interesting side effect.
