The native language of AI.
CIS is a device-independent intent protocol. It defines what AI wants to do — purely semantic, transport-agnostic, backend-agnostic. Through a local static mapping layer, a single CIS intent losslessly translates into CLI commands, GUI interactions, TUI operations, or CSS feedback.
CIS is the soul of the CIS/CAP protocol family.
